A Description of Yaesu FT-M100DR/DE for the blind – Not Technical but Tactile

Let’s start with the front Panel Button Layout

Top Left On / Off / Lock

Below Volume control

Below are a row of buttons easily identified because of the casing either side of them. From left to right they are;
1 Band A / B, 2 TX Power, 3 VFO / Memory, 4 Mode, 5 Group Monitor, 6 Squelch / Digital Voice, 7 Back, 8 Settings DSP.

Top Right, 1 Megahertz step.

Below a ratchet selection knob.

At first unpacking the transceiver I thought it to be quite odd. The top has a raised area that contains the speaker. The front panel feels like a bolt on being considerably taller than the height of its body. Further more the body is metal wile the front panel is a plastic box. I haven’t seen a radio before also that has a power cord fixed to the radio. Although, this is a short wire with a connector at the end. In the box was a long power lead to connect to this pigtail. Considering the back panel. I have never seen a radio with a fan housing sticking out of the back. This design has the advantage of providing a recess so that antenna, headphones and data plugs and leads cannot be crushed against anything behind the radio.

Included in the box was an extension lead for the front panel. By pressing a hard to find button on the left front side of the radio the front panel can be removed. In fact, this is necessary to do in order to attach the microphone. Critics have argued that Yaesu should have also included an extension lead for the mic as if the extended front panel lead is used the mic is likely to require an extension too. There are three other metal parts in the box. One bracket that saddles the radio body and a 3 sided bracket that is for the front panel. There is the traditional mic clip too. In addition there are other little odds and ends such as an adapter to be used if using a mono extension speaker.

The FT-M100 dimensions are 165mm from front to back, 135mm across the front and 40mm tall.

So How Accessible Is The FT-M100?
Sadly, the first time the radio is turned on or a factory reset has been performed. The radio demands the entry of a callsign. This process is not intuitive nor does it speak. I did complete it with support from an AIRA agent via an internet video link. However it was painfully slow owing to the brightness of the LED panel. The default is max brightness. I have turned the brightness down to about half way (Settings Menu 1) and agents don’t have difficulty reading the screen via an iPhone camera. The app seeing AI provides some useful feedback but not enough to change settings in the menus independently.

The manual suggests that if the FVS-2 voice board is fitted the frequency will be read on demand. This may be true if menu 12 voice guide is set to manual however, the other buttons don’t speak. The default is auto. Which means that the two buttons VFO A / B and VFO/ Memory read the new state. Using the mic to input a frequency or a memory number are spoken too. Because of the variety of tones used many of the buttons provide useful orientation. e.g. the TX Power button provides three tones the high power tone is higher in pitch than the other two tones.

Yaesu provide software to clone the radio settings and write them back to the radio free of charge. The software appears to be quite accessible. My Windows 7 machine assigns a com port and I can set it within the software. The lead is provided and my Windows machine did not require a driver. I understand that when I use a Windows 10 PC I will need to use a dedicated driver as it uses a Prolific driver, which Windows 10 replaces with a universal driver I can read from the radio and fill a data sheet with current settings. By loading the software and after checking the com port settings are correct I select read from radio. A dialog appears stating the steps that need to be taken. Select menu 13 then 7 for clone. The radio asks for direction i.e. from radio to other. Then the insecure nag are you sure with the default on cancel. One click anti-clockwise of the selector knob moves focus to OK. There isn’t much time after pressing enter on the PC’s keyboard and then quickly finding the Settings / DSP button on the radio I can start the read from radio process. After the write to PC the screen returns to the main screen having exited the menu system. NVDA reported an error although there was no dialog on the screen. By pressing the right arrow it moved focus from VFO A to VFO B and a simple press of the tab key enabled me to curser through those frequencies I had programmed into the radio. I am going to spend some time amending my data and try to write it back to the radio.

Regarding the supplied six pin mini din USB data lead, SCU-20. Thee socket is on the back panel left-hand side of the fan and underneath the power cord which is not the easiest of locations. By exploring the six pin plug I can feel a flat on the shroud and opposite that flat is a groove. This flat is at twelve o’clock and the groove at six o’clock orientation to go into the socket.

I believe the SD card slot is behind the front panel as well as a selector switch for firmware updates. There is also a reset button and another firmware switch under a rubber bung on the top left-hand side near the front of the radio’s outer casing. Also behind the front panel is where the mic socket is located mentioned earlier. Menu item 13 is where the current versions of firmware are stated.

In summary:
This differently shaped transceiver is the most accessible Yaesu I have looked at. Sadly there is a lot of room for improvement to match the competition, in terms of accessibility. The radio is quiet usable on a day to day basis. But when a blind user needs to set up a new or reset radio. Or even a simple adjustment to a menu setting sighted support is a must. Having said which, I have always been a Yaesu fan and I love this radio I think it is great value for money and is a keeper.

My sincere thanks to John KD8PC who created an audio demonstration of the FT-M100 which can be found on the blind hams archive. I would suggest anyone seriously considering this transceiver to listen to John’s demo. Thanks John for your support and for taking the time to create your audio demonstration because I would not have known about this little beauty.

Kenwood TH-D74 Accessibility Review

Accessibility Review of the Kenwood TH-D74

Close up photo of the th-d74 Rig

By Kelvin Marsh M0AID

December 2016

Background

I was contacted by Jim MI0JPC in September 2016, asking if I had any accessibility information on the new Kenwood TH-D74 handheld. The model had been discussed on the Active Elements email group a few weeks earlier, but despite the radio’s obvious potential, no one had any firm details.

The TH-D74 had the prospect of being the first handheld with full speech output and accessibility to D-Star. I have very limited experience of using handheld portable radios, and the low cost handheld I reviewed a few years ago only ’spoke’ the key that had just been pressed. It could not be interrogated further to learn the current frequency, and it left me feeling that only part of the accessibility job had been done.

The Kenwood TH-D74 had the potential to be fully usable by a blind amateur, and the spec was impressive. It is a 2m and 70cm Dual Band handheld with full voice Guidance and D-Star. It has GPS, APRS, wide band coverage, including SSB on 2m and 70cms, and FM broadcast coverage. It would offer a plethora of programming possibilities, without a blind operator having to remember a set number of beeps or clicks.

Basically, the radio sounded like an ideal unit to review for accessibility. I asked Mark M0DXR of Kenwood UK if he would loan me a unit, and I have to say a big thank you to Mark for sending me the review radio for a couple of weeks. To make sure I could get onto the D-Star system I was also loaned a Digital Voice Access Point DVAP by Jeremy G4JZL.

Preparation

Before receiving the radio, it seemed a good idea to prepare myself by grabbing the PDF manual from the Kenwood site. While 99.9% of the manual was easily read by using PC screen reading software, some buttons, such as the arrow keys, are shown graphically as pictures of arrows. When read with a screen reader, a picture is ignored. So, for example, when I read the PDF manual, I learnt that you turn on the power by pressing [ ]. OK, you can work this one out, but if the command involves presses of several buttons that include the arrow keys, and these are being ignored, you cannot learn how to operate the radio.

I can fully appreciate the PDF manual will refer to a button as Menu, because Menu is written on the actual button. Likewise, if an arrow is printed on the real button, it makes perfect sense to show a picture of the arrow symbol in the manual. Sighted readers naturally expect this kind of consistency.

When you consider the tremendous effort Kenwood have gone to in making this radio accessible for blind operators, it is such a shame the manual is so hard to use. It would be incredibly helpful if Kenwood would produce a separate text only manual. The graphics being ignored are a very small number, but nevertheless, crucial!

To get over the immediate hurdle, I extracted the text from the PDF manual into a document, and Steve M6HFH went through it, replacing the blanks with text labels, such as ‘Right Arrow’ and ‘Power On/Off’. Jim MI0JPC has subsequently divided it into separate TXT files for easier navigation.

Discussing this with blind amateurs on the Active Elements email group, folk indeed like using text manuals, particularly for the ability to rapidly navigate and search them. There is general agreement that both PDF and HTML documents work extremely well, if properly structured.

D-Star Operation

I was able to rapidly establish that as a standard analogue multi-mode handheld the D74 has excellent accessibility, but the handheld also offered unparalleled access to D-Star. As primarily an HF operator, I only had a notional idea about D-Star, and I had found it easy to overlook. Having now used it, I’ve come to the conclusion that it is just another way of communicating, but with some great benefits. For one thing, you can talk and exchange greetings and ideas anywhere in the world, do so in audio comfort, and without the need for a large antenna system. This could be a great way of continuing with the hobby if you have severe antenna restrictions or even if you go into a residential home.

Getting D-Star working is a great deal easier if you already know someone using it. Rob G0WSC has been using D-Star for a while, and was able to answer many of my questions. There is a fair amount of new terminology to learn and initially the plethora of connection methods is daunting. This is not just initially daunting for the blind amateur, but seemingly for many operators. Like many things in amateur radio though, the picture becomes much clearer and simpler the more you use it.

As I’m a long way from a D-Star repeater, and very unlikely to be able to access one with a handheld, G0WSC suggested I use a Digital Voice Access Point or DVAP, and connect directly into the D-Star backbone. This means I could bypass the Repeater system. This inevitably means my review of using the D74 might well be different from your experience!

A quick note about the DVAP. I was loaned a 2M DVAP by G4JZL for the period of the evaluation. The DVAP connects via USB to a computer, in my case a Windows PC, and the appropriate software is installed. The Th-D74 then transmits and receives on a simplex frequency, in DV mode, using the DVAP.

The DVAP Windows software is not without accessibility issues. I found the setup screen did not give any feedback , using any of my screen readers. There is a second screen and you can switch to this with Alt+Tab. This screen can be read by screen readers and will show the setup screen, but you must switch back to the first screen to change the input parameters and switch back to the second screen to read any changes!

The salvation of the DVAP software is that once setup is complete, no further changes are needed. I just ran the software, tabbed twice on the unreadable screen, and pressed Enter. The connection was opened. I could then switch to the second screen and get feedback if required.

Audio Demonstration

In previous accessibility evaluations I’ve written a lot, and recorded a little. This time it seemed sensible to record as much of the Voice Guidance of the TH-D74 as possible, and this actually became a collection of short recordings that now total about 80 minutes. I have placed the separate MP3 tracks into a zipped file, available from the following link:

TH-D74 MP3 Audio Demonstration

The separate MP3 tracks are:

1 General Description 5:57
2 Introduction to Menus 3:12
3 Frequency Input 2:32
4 Squelch 1:21
5 Power Adjustment 0:40
6 Dual Band Operation 6:47
7 Memories 7:01
8 Programmable Function Keys 4:14
9 FM Repeater setup 3:39
10 DVAP 9:22
11 D-Star through DVAP 28:0
12 D-Star through Repeaters 8:10

The only key combination I will mention here is how to turn on the Voice Guidance. Simply hold the Hash key when you power on the radio.

Conclusion

If you haven’t listened to the audio tracks, you’ll still want to know if the radio is accessible. With some minor accessibility exceptions, the radio is brilliant. Not only does it give unparalleled feedback to the usual analogue operation, it includes full access to D-Star. I was unable to try APRS and the MCP programming software in the limited time I had the radio. I switched on the GPS function so I could use the Nearby Repeaters list, but I did not pursue further investigation of GPS features, beyond this.

The review radio had version 1.0 of the firmware, and at the time of writing, version 1.04 is available. Future firmware updates hopefully also give the possibility of further accessibility improvements.
Once again, Kenwood have approached accessibility very seriously for the blind operator, and done an impressive job.

Kenwood TS-990 Accessibility Review

Accessibility Review of the Kenwood TS-990

By Kelvin Marsh M0AID

July 2013

It’s not often that one of the main amateur radio manufacturers launches a new flagship model. When Kenwood announced the TS-990S it naturally caused great interest, and I was intrigued to learn the radio would include an integral voice unit. Other recent Kenwood models can be fitted with the optional Voice Guidance and Storage unit, the VGS-1, and the built-in voice guidance might mean there was an improvement to accessibility, or might mean a reversion to former more basic functions. As you read on, you’ll see I was extremely impressed by the work done by Kenwood, and the TS-990S has made huge accessibility leaps forward!

The Radio

The TS-990S is a large 200 watt base station, allowing transmissions on HF and 6m. It has an integral ATU, and is mains powered. It has connections for 4 TX antennas and an RX antenna. I measured the size of the casing to be approximately 460mm wide, 160mm high, and 400mm deep, excluding front panel controls. The feet add about 40mm, making the actual height more like 200mm. This is an imposing radio!

It is sadly inevitable that much that the TS-990S has to offer will be unused or unappreciated by a blind operator. The radio has large vibrant displays, and these caused quite a stir from several of my sighted friends. The TS-990S has many data decoding options and display graphics, and I spotted in the manual it can even be used for logging, using a USB keyboard.

There are varied alternatives for getting audio into and out of the radio, and as well as Ethernet, USB and serial connectivity to a PC, both optical input and output is available, along with USB drive storage.

Undoubtedly, one of the prime attractions of the TS-990S is the ability to have two independent cross band receivers. Anyone who seriously works DX, will immediately understand the advantages of listening simultaneously to the TX and RX frequencies of the DX station.

I think that if you want to know more about the radio’s capabilities, you would be wise to read the full technical review by Peter Hart in the June 2013 RadCom. This is available in MP3 format in the Related Downloads section below.

This evaluation is looking solely at accessibility, and how the TS-990S can be used by a blind operator. I am very grateful to Kenwood Electronics UK for the loan of the review radio.

First Impressions

My first impression of the TS-990S was somewhat daunting! There are lots of controls, but it soon became apparent that Kenwood had brought all of the commonly daily used controls onto the front panel. Whilst initially overwhelming, it didn’t take long to realise I recognised every control, and they all made sense. This radio is geared up for quick and seamless operating, and while there is undoubtedly a learning curve, you won’t be digging into the menus just to increase the power.

As previously mentioned, there are two displays. The largest is positioned on the left at the top of the front panel, the smaller is approximately in the centre top with the main tuning VFO below, and the right third of the front panel is given over to button and rotary controls.

All of the buttons are a hard flat plastic, meaning there is no unpleasant dragging on the finger tips as you feel for a control, and the buttons are flat and without lumps and bumps. There are many different shapes and sizes of button, and it will take some time to become fully accustomed to their layout. In fact, I think the manual will almost certainly become your best friend, for a while at least!

Layout

In slightly more detail, there are buttons in a vertical column at the far left of the facia, and to the left of the large display. These include The power on, Timer, Programmable Function A, Send, and Auto ATU. There are 7 function keys running along the bottom edge of the main display, and a series of rotary knobs below the function keys. These are typical concentric inner and outer rotary knobs, and control Mic and VOX Gain, Processor levels, TX power levels, Key speed and Delay, and CW pitch and Monitor level. Just above and in-between these knobs are 4 further buttons related to the function of the knobs themselves.

A vertical column of 7 buttons is positioned between the displays, and they include control of Antenna selection, Pre- amp, TX power limits, the display Meter, and TX filter. Below this column are the vertically arranged Mode buttons announced with CW, and to their right, the main tuning knob.

To the right of the smaller display and Main tuning dial, at the top, is the numeric keypad, with markings on the 5. This has 3 buttons above including RX antenna selection, and transverter, and the Menu button is in the row below the keypad. Below this is the main block of buttons. These include Main and Sub band selection, with Up and Down buttons in a group. A group of 9 buttons operate the Memory system, RX record and play back, and Quick Memory.

There are 6 buttons in 2 groups of three, positioned above and either side of the main tuning knob, controlling the use of the two receivers and the Split function. There is a column of buttons to the right of the main VFO for Fine tuning adjustment, Main Voice, and main Lock. Continuing to the right along the bottom of the front panel is the smaller Sub tuning dial, and the Fine, Voice, and Lock are mirrored for the Sub receiver.

Moving to the top of the facia and to the right of the keypad is the RIT adjustment knob, with related buttons below. Below this is the Multi-Ch control, with 2 columns of 3 buttons below, for Diversity reception, PF B, AGC, and RX and TX Equaliser. It is nice to find the equaliser controls have found a place on the front panel. Below these buttons is the previously described Sub tuning VFO.

Back at the top and to the right of the RIT, are inner and outer rotary controls for Noise Blanker 1 and 2, and then Noise Reduction 1 and 2 in the top right corner. These are turned on with buttons below each knob.

Below these, and to the right of the Multi-Ch control are inner and outer rotary controls for Main Notch and Squelch, and Sub Notch and Squelch. Below these controls are buttons to control the Notch behaviour on each receiver.

Below the Main Notch knob is the band pass control. a rotary concentric inner and outer knob allow the band width to be changed.

To the right of the band pass control are 8 further buttons to control the AGC, Noise Blanker 1 and 2, Noise Reduction 1 and 2, and APH, for the sub receiver.

Finally, the bottom right corner has separate concentric inner and outer controls for main and sub AF and RF gain.

For a comprehensive front panel layout, see below in the Related Downloads section.

A note on the layout. Make no mistake, this is a complex radio! There is a large block of buttons extending below the keypad, and my sighted friends initially expressed some concerns that none of the button groups lined up with their neighbours. In reality I’ve not found this a problem, but the button area is busy. I think that having a varied tactile layout can aid navigation, and as I’ve become accustomed to how everything fits together, I’ve found the different shapes and positions actually helps me find the needed control. The manual is currently available in PDF format, and I found it quite easy to use with the Window-Eyes screen reader, and it is essential reading to understand the TS-990S operation. As a blind user, you will certainly also need a full front panel description in the learning stages.

One small criticism about the numeric keypad, I personally don’t feel there is enough space around it for rapid tactile use. There is a row of 3 keys directly above and below the keypad, and only the slightest increased separation between them. I can’t help feeling that over the course of the radio’s life, a blind user will potentially use the keypad thousands of times and very swift operation is only possible once the first button press has been verified as correct. Saying that, the keypad is fully voiced, which is a tremendous asset.

Preparations

The TS-990 has the integral automatic announcement voice guidance switched off by default. As a blind user, you will want to turn it on. This can be done through the menu system, but the easiest method is to hold the PF A button when the radio is switched on.

Kenwood have been able to loan me the radio for just over a week, and I will be the first to admit the rich feature set of the TS-990 will need much longer to investigate fully. I discover something new in terms of accessibility every time I switch on the radio, and you will understand why as you read on.

Traditionally, amateur radios have been made accessible by announcing button presses, and announcing the result of any changes. The TS-990S does not slavishly follow this convention, but has taken huge strides in accessibility by giving spoken announcements to the changes being made on the displays through the Function keys. This means that even the very advanced options, such as recording audio messages, can be easily managed by interacting directly with the display a sighted operator uses!

I normally write about the great Kenwood accessibility to the menu and memory systems, and all of this is spoken as we have come to expect from Kenwood, but we are not used to having such accessibility to the more advanced functions of high end radios. The TS-990S, in my opinion, has moved the game forward in leaps and bounds.

It seems to me that the traditional menu system is now more reserved for adjusting little used settings, the kind of options you set and forget. All of the more commonly used features have either been given their own control on the front panel, or are adjusted on the main display using the Function buttons running along the bottom of the display. I believe it is this accessibility to using the Function Keys that really sets the TS-990S apart.

Once I had started the automatic announcement of the Voice Guidance, by switching on with the PF A key held, I decided to install the Kenwood ARCP software on my PC. This is free from the Kenwood site, and it immediately gave me access to the menu system via the PC, using my screen reader. The Menu is accessible using just the radio, but only the menu numbers are spoken, and you will need an external list of the menu structure to browse through it successfully.

The big advantage of using the ARCP software is that it is accessible, and each menu option is described. I’ve not actually spent much time investigating the software, but the pulldown menus seem to work well, and it seems to me this is certainly an easy way to make Menu changes. Any changes made using the ARCP are immediately seen on the radio, and similarly, any changes made to the menu on the radio were immediately seen on the PC.

Using the software, the Menu is shown as a Tree-View, and each group is then opened to show the options. When you want to make a parameter change, just tab through the Checkboxes.

If you use the rig to make menu changes, just press the Menu button, move through the options with the Multi-Ch control, and press F4 to select. The use of the F4 function key, as the selection button, was my introduction to using the function keys.

As is my preference, I was able to set the Multi-Ch control to 1kHz steps for each rotary click, and the frequency is moved to the round figure. This means I can tune for a signal, and providing it is on a round frequency such as 7.106.00, I can make the final tweak with the Multi-CH control.

I also like the VFO to move by 5kHz for every complete revolution of the main VFO, and this was easy to set. When the Fine frequency button was engaged, each revolution then moved by 500 Hertz, meaning I would move from 7.100.00 to 7.100.50. I was also very pleased to see the frequency was announced to the Hertz level with the Fine adjustment engaged. The frequency is announced as 7.100.500.

Operating

Over the course of the evaluation I found that visits to the Menu were very infrequent. As I’ve previously mentioned, all of the common functions of the radio are controlled from the front panel. I found that when I needed an announcement I got one, and when the voice would have been obtrusive, I got useful beeps.
I guess the Antenna change button and the Attenuator buttons sum up this approach. These buttons are in the column between the displays. Press the top button for aerial selection, and you hear ‘Antenna 2’. Subsequent presses give ‘Antenna 3’ and so on.

Move down to the Attenuator button and you hear one high pitched beep for 6dB, two beeps for 12dB, three beeps for 18dB, and a single lower tone for off. Holding the button takes you in the reverse direction.

The third button in the column is the Preselect. This button Beeps for on and off with a momentary press, and when held it announces the setting, and can be adjusted with the Multi-Ch control or the function keys. F1 held, will reset back to default.

The fifth button in the column, the TX Power Limit button, allows you to set power limits on each band, and between data, non data, and Tune.

MP3 Demo of Power Limit Setup

The TS-990S has many options for assigning programmable function buttons. There are two dedicated buttons on the front panel, labelled PF A and PF B. By default, the PF A key announces incoming signal strength, or outgoing power when sending RF. PF B works in conjunction with the Meter button, and can announce Power and SWR when transmitting.

The Up and Down buttons on the microphone can also be assigned as PF keys, and an external unit can be constructed for eight additional PF keys. The optional MC-47 fist microphone has 4 extra buttons available for programming, and I calculate this would give the dizzying possibility of 18 programmable keys. As so many functions can be assigned to a PF key, this gives lots of options to move commonly used keys to somewhere more easily accessed.

Traditionally, the frequency announcement itself has been assigned to one of the available PF keys, but the TS-990S has two dedicated Voice buttons for both the Main and Sub receivers, so the PF keys are not needed for frequency announcement.

Continuing with our look at the vertical column of buttons between the displays, the sixth button, the Meter selection, is a pleasure to use. Among the options, the SWR, ALC, and Power are announced by transmitting RF and simultaneously pressing the PF B button. On the Meter screen, Processor is only announced if the Processor is enabled.

I found the lower left row of rotary controls very easy to use, as although there is no voice announcement on the majority of them, the notch in the control can be felt. If we look at the first knob, the inner is the Mic Gain, and the outer the VOX Gain. Using the adjacent button gives access to the VOX Delay and Anti Vox setup on the display. Changes are made with the function keys.

MP3 Demo of VOX Setup

Split operation is very slick, with a dual watch function allowing the Main and Sub RX to be separated into left and right ear pieces. I needed to enter the menu to set the 50/50 balance for the headphones. All of the Main and Sub functions work very well, and Split operation is clearly announced.
A momentary press of the Split key announces ‘Split On’.

Holding the Split key announces ‘Split Enter’. If you then press a 5 on the keypad, the Sub receiver is instantly set 5kHz higher. If the Main is set to 7.100, you hear ‘Split TX 7.105’.

MP3 Demo of Split Operation

As we have come to expect with Kenwood radios, the memory system is accessible. As well as storing Simplex frequencies, using the F6 key when storing, Will allow the Sub band to be included. When subsequently scrolling through the memory channels, the duplex channels are announced with a ‘D’, and simplex channels with ‘S’.

The TS-990S has 6 channels to record voice messages. The messages are controlled using the function keys, running along the bottom of the main screen. Again, these buttons give enough spoken feedback for operation without sight.

To record a voice message press F2, you will hear ‘Voice Message’.

Press and hold F2 through F7, which corresponds to message channel 1 through 6. If you press and hold F2 for message channel 1, you will hear ‘Record Mic’. At this point you can change the input source, but the default is mic.

Press and hold F4 and make your recording. If you press F2, your message is played back.

MP3 Demo of Audio Messages

Setting the CTCSS tone is a good example of the TS-990S accessibility for lesser used features. Firstly, change the mode to FM, and press and hold F4. You will hear ‘Main Tone 88.5’.

Next press F6 to select the Main or Sub band. You will hear ‘Main’. F6 now toggles between Main and Sub.

Use F2 and F3 to switch between Tone and CTCSS, and use F4 and F5 or the Multi-Ch knob to move between the frequencies.

Press Escape when you’re done, and remember that holding F1 resets back to the default.

MP3 Demo of CTCSS Setup

Recording communication audio. You can record a maximum of 30 seconds of audio data per file to internal memory or a maximum of 9 hours of audio to a USB thumb drive. I found the Record, Stop, and Play buttons allowed me to capture received audio, and replay it instantly. Pressing F1 announced ‘Audio file’, and I was able to move through each of the previously recorded clips and play them.

AGC. The AGC buttons are available for both the Main and Sub receivers. There are full announcements for Fast, Medium, and Slow, along with their values. Holding the AGC button enters the AGC setup, and the values are easily adjusted and saved.

MP3 Demo of AGC Operation

I’ve mentioned the memory channel system is fully accessible, and the quick memories work well too. Interestingly, pressing Enter, and then rotating the Multi-Ch control, takes you through the history of frequencies entered through the keypad. A very nice touch, and again all announced.

Briefly, I found the Timer functions were announced, and while I did not complete the setup, programming the clock and setting a sleep timer all looked to be accessible. There is a Lock key for each receiver, and similarly two Mute buttons. Very usefully, I found the radio would announce its status at switch on, if it had been left in setup mode, or in Split mode, when it was switched off.

Conclusions

In summary, I am incredibly impressed with the accessibility built into the TS-990S. It seems the voice announcements allow the operator to make almost any change, as a sighted user would. I installed the ARCP software and this meant I could browse the menu system with descriptions, but whilst useful, it is not strictly necessary, as the menu plays a more minor role in this radio. Having the radio for just a week meant there is much more to discover, and no doubt much better ways of doing things, but I’m sure the audio demonstrations will give you a good idea of the tremendous work that has gone into making this radio fully accessible. Congratulations to Kenwood, for a flagship radio with truly superb accessibility!

Kenwood TM-V71E Accessibility Review

Accessibility Evaluation of the Kenwood TM-V71E

By Kelvin Marsh M0AID

June 2013

The Kenwood TM-V71E is a mobile VHF and UHF transceiver for FM communication. There is not a terrific choice available for a blind amateur in this market with accessibility, and if you want a multi-mode radio, your best bet is probably one of the so called ‘shack in a box’ transceivers that also covers HF.

The TM-V71E has been around for several years, and is considered to be near or at the top of the shopping list for blind amateurs wanting a 2m and 70cm FM radio. Although generally accepted as one of the most accessible radios in this market, I thought it would be worth evaluating the TM-V71E, and I thought it was useful to jot down some of my findings.

I don’t intend to write a full review, and I am delighted that there are so many accessible resources available to get you started. Under the Related Documents section on this page are an MP3 review and demo by David 2M0TSR, the full manual recorded in MP3, and the full manual in HTML format. Each describes the layout and operation, and I would encourage any owner to check them out.

I have evaluated the TM-V71E, and this is the European version. I believe the other versions are very similar in operation, but with frequency allocations more appropriate to their region.

As I am almost entirely an HF operator, I was initially surprised by the small size of the TM-V71E! I’ve approximately measured the width to be 140mm, the depth 190mm plus front controls, and the height about 40mm.

The radio has one N type antenna socket, computer and TNC sockets, and will support two external speakers, one for each VFO. It transmits on 2m and 70cm, and has three power levels. Low is 5 watts, Medium is 10 watts, and High is 50 watts. There is no numeric keypad on the front panel, but the chunky microphone has a keypad, and 4 additional programmable buttons. The radio can also be used to receive frequencies outside of the amateur bands in FM and AM modes.

The front panel controls are very well defined, and the buttons are a hard plastic giving no finger drag as you move from control to control. There is a small tuning knob at the bottom left of the facia, And this clicks as you tune through the frequency steps. This knob is also used for selecting memory channels and moving through the Menu. The bottom right has two Volume and Squelch knobs, for independent VFO a and VFO B control. These knobs and the Tuning knob can also be pressed for additional functions.

The test radio was fitted with the optional VGS-1 voice guide. This gives spoken access to the majority of button presses, but I must stress that there is still a need to read and understand the operating guide, as the radio is surprisingly complex in use, and there are several potential pitfalls just waiting to trap the casual blind operator .

The Memories are spoken, giving accessibility to the storage of repeater programming, and the Menu system can be navigated with speech output. In line with other Kenwood radios I have tested, the Menu channels are not fully described as you move from item to item, and it is necessary to have an external reference list at hand.

Menu access is achieved by pressing the Function key followed by the Tuning knob. You are given the spoken prompt ‘Menu 001’, and further turns of the Tuning knob click through to ‘Menu 002’ and so on. As you move through the menu, the selected parameters are not automatically spoken for each menu. I found I had to press the Tuning knob to be placed into a talking list of the parameters. A further press of the Tuning knob saved the setting, and returned me to the menu list.

Using the microphone keypad, it is very straightforward to enter a direct frequency, but first, one of the Programmable Function (PF) buttons must be designated as Enter. I found that it was ideal to use one of the four PF buttons on the mic for this purpose, and menus 509 to 512 can be used to set these buttons. I found the PF keys seem to be programmed in the reverse order to my expectation. For example, 512 is the top PF button on the mike, and 509 is the bottom button.

The tone key cycles through Tone, CTCSS, or DCS, and Off. These functions are not initially spoken, and each setting has the same higher pitched beep, with the Off position having a lower beep. I also found that when on the CTCss and DCS positions, the radio usefully became silent, as only signals with the appropriate coding are allowed through. I guess this might cause some head scratching if the tone button is pressed accidentally.

If I needed to set the CTCSS, I pressed the Tone button until I heard the lower pitched beep of the Off position, pressed a further two times, and pressed function. Now, a further press of the Tone button would speak ‘CTCSS frequency 88.5’. The tuning knob is then used to make the selection, and a further press of the Tone button saved the setting.
In its simplest operation, I found the Rev key worked by switching the input and output frequencies when listening to a repeater. I briefly investigated the more advanced Rev functions, and I could change the plus or minus offset frequency. Pressing Function followed by Rev toggled the settings between Off, minus, and plus. The Off position, where there is no offset, gave a low pitched tone, and plus and minus gave a higher pitched tone. At each stage I pressed VFO A volume control to read the frequency, in conjunction with the Rev key, to find out what I had changed. There is plenty of scope for confusion using this function, and I suspect there will seldom be a need to use it beyond initial setup, and possibly never.

Here in the UK, the 2m repeater outputs are in the frequency range 145.600 to 145.800. I found that entering a frequency in the repeater block automatically set the correct offset for the transmit. It is then just a matter of selecting the right CTCSS tone and saving to memory.

As we have come to expect from Kenwood, the memory channels are fully accessible. The channel numbers are spoken and their status is announced. If you have lots of repeaters in your area, it would be useful to maintain a list of frequencies and the memory channels used. There is a facility to label memory channels, and while the actual labelling process was inaccessible, I did add one label, with sighted help, to see what happened. Unfortunately, only the channel and frequency were spoken, the tag was ignored.

Since I started to evaluate the radio, I was intrigued by the voice announcing ‘PM2’ at the power on. Investigating further, the radio has 5 Programmable Memory states. This allows a single user to setup the radio for several types of operating or for use in different localities. It also means that several different users can tailor the functions to their particular preference, and store the individual setup.

This system is again accessible, but I think could cause a degree of confusion if the wrong buttons are pressed. Imagine setting up the PF keys on the microphone in PM1, and then accidentally moving to PM2. All the settings still reside in PM1, but appear to be lost.

With this scenario in mind, the way of changing the PM status is as follows. Simply press the PM button until ‘PM’ is heard, and then press one of the keys running along the bottom of the front panel. The Call key turns PM mode off, the Function key moves you to PM1, the tone key to PM2, and so on.

The memo and conversation functions of the VGS-1 work as described in the manual, and can be easily used.

Unfortunately, I could find no way of having the VGS-1 tell me the incoming signal strength.

Overall the Kenwood TM-V71E is highly accessible, but there are still some areas where the blind operator has to infer the information, rather than being told it explicitly. I am personally surprised at the complexity and rich feature set of this small VHF and UHF radio, and it is certainly a unit where the manual needs to be read thoroughly. Once again, Kenwood have worked extremely hard to make the TM-V71E very accessible through the VGS-1 voice guidance system.

Elecraft KX3 Accessibility Review

Accessibility Evaluation of the Elecraft KX3

By Kelvin Marsh M0AID

May 2013

The KX3 Is the first Elecraft radio I have tried. Several of my amateur friends have been using Elecrafts for several years, and the brand certainly seems to engender a loyal following!

I have had the opportunity to borrow a KX3, serial number 1907, while my friend G4JZL has gone on holiday. Reading comments from others on the Active Elements email group, I count myself very privileged to have been entrusted with such a prized possession!

The KX3 in this evaluation used firmware version 1.1.2, a very early firmware version. The very latest Beta firmware in early May 2013 is 1.4.7, and Rob K6DQ has tried out some of my findings with version 1.4.4. Rob describes the firmware progress as being akin to having a new radio every few weeks, and it is interesting to note the improvements already made to the CW readout in recent upgrades.

I have only spent a few hours with the accessibility documentation, and I feel I only understand the basic operation. Due to the rapid development of the KX3 firmware It is very likely that the findings in this review will have changed again, or I have overlooked something obvious!

The KX3 is an HF radio covering from 160m to 6m. The power output is up to 10 watts from an external power source, and it has an internal battery and an internal auto ATU capable of matching a 20 to 1 SWR. There are many optional extras such as the 100 watt amplifier and the narrower roofing filters, and the microphone is itself an additional option.

While primarily a portable radio, the KX3 has base station receiver performance in several areas. The April 2013 RadCom review by Peter Hart was very favourable, and on paper some of the figures were comparable with the very best.

It is perhaps too easy to categorise the KX3 as a CW only portable radio, but I can confirm it sounds excellent on SSB transmit, and I found during my testing that the noise reduction on SSB reception is superb. Listening with the KX3 to a weak DX station on a noisy frequency, the Noise Reduction excelled at reducing the fatigue of listening to a weak signal through the crackles and hiss of HF.

My initial impressions of the KX3 was that it was a shape and size unlike anything else I have used before. It is about 200mm wide, 100mm deep, and 90mm high including controls. I can best describe it as being in the shape of a house brick, with the controls on the top surface.

The KX3 has a BNC aerial socket on the right side, and power input and sockets for microphone, Morse key, headphones and PC connection on the left side. There are future plans for an additional 2m antenna connection, and you are given the impression the KX3 is very much at the start of the development cycle. As the KX3 is offered as a kit, I speculate that some of the hardware improvements, such as the 2m VHF capabilities, might be offered as a module for existing radios.

I will describe the top panel as though you are looking down on it from above, in a plan view.

There are 6 buttons on the far left, running from top to bottom. These include the up and down band buttons, the direct frequency initiation, and the auto ATU. The bottom button is the zero in the numeric keypad.

6 more buttons run along the bottom of the panel, starting in the bottom left corner next to the zero button, and ending about two thirds of the way along the facia. These buttons control receiver functions such as Pre-Amp, Attenuation, Noise Reduction etc. These buttons toggle settings on and off with a momentary tap, and toggle other settings with a longer press. An abbreviated CW announcement is given for every press. The pitch of the CW changes as commands are switched on and off. These buttons also act as 1 through 6 in the numeric keypad.

Above these buttons are 3 rotary knobs. As well as turning, these knobs can also be momentarily pressed or held. Often a function is entered by pressing a knob, and the adjustment is made by turning the same knob. Again, you are given adequate CW feedback at each stage. These knobs also act as 7 through 9 when used for frequency input.

To change the transmit power, the third knob is held for about half a second. A beep is heard, and adjustment is made by turning the knob. There is CW feedback when you pause turning the knob, and typically you will hear:

4 R 6

Meaning the output power is set at 4.6 watts.

When in SSB mode, the second knob can be used to control band pass filtering. Tapping the knob switches between High and Low cut, and rotating the knob changes the filter width. A longer press puts the filtering back to normal. You are given CW feedback for High, Low and Normal positions.

Above these 3 knobs and virtually in the top centre of the facia is the LCD display.

The main VFO tuning knob is to the right of the third knob described previously, about three quarters of the distance from the left edge, and finally to the right is the Sub Band tuning knob. This smaller tuning knob is also used for RIT and XIT tuning, and for scrolling through the menu.

There are 6 buttons in two columns of three at the top right of the panel. These buttons change the Mode, and control the swapping of frequencies between the Main and Sub VFOs and the Split functions. The bottom two buttons of this block are programmable, and can be assigned to menu options.

Finally, there are a further two buttons at the bottom right for changing tuning step size and for announcing frequency in CW. The bottom right button also accesses the configuration menu when held, And when not used for CW frequency readout is used for switching the VFO B area of the LCD display to show various parameters, such as power supply voltage, battery voltage, current draw temperatures and other non accessible info. It is worth mentioning here that the HamPod reads all of this information, and this is discussed later.

In terms of usability by a blind op, it is very interesting to discover how Elecraft have put considerable thought into accessibility. The radio can be setup to produce CW feedback for almost all of the controls. This means the KX3 is highly accessible if you read CW. The CW announcements are turned on in the menu system, and it would be nice if this was an option assigned to one of the programmable buttons as a default. It would mean a blind customer could purchase the KX3, turn on the announcements independently, and start using it without sighted assistance.

Although the menu system gives no aural feedback at this stage, the accessibility documentation indicates that Elecraft plan to give CW access to the menu system in future firmware upgrades.

I think that one of the most exciting aspects of this KX3 review is the discovery of the accessibility documentation prepared by Elecraft. The document is specifically written for blind operators, and describes the radio controls. You are encouraged to read the full manual for more in depth information, but the accessibility documentation covers the basic operation of each control. One improvement that could be made to the accessibility documentation is to give each control a structured number. For example, I added A-1, A-2, etc to each of the 6 buttons on the left side. The 6 buttons along the bottom edge became B-1, B-2, etc. Without this additional indexing, it is unnecessarily difficult to search the file, to find the purpose of one control. Similarly, by assigning each control an individual reference number, I can search for ‘Split’, and instantly see it is button C2.

There is a copy of the accessibility document at the foot of this page, and I would imagine it will be updated as new features become available. I would therefore encourage you to find the latest copy yourself as it is unlikely I will be able to keep it up-to-date.

Unless you have a HamPod, having just CW feedback available will no doubt limit the radio’s appeal to non CW operators. The CW feedback speed can be slowed to accommodate a beginner, but it can become laborious as the CW speed decreases.

With the early firmware version on the test radio I could not find a method of interrupting the CW readout once it had started. For example, if I used the band up button to move from 40m to 15m, if I pressed the button quickly, I rapidly moved through 30m, 20m, 17m and onto 15m. The 15m frequency was then announced in CW. If I pressed the band up button slowly, I had to listen to the complete 30m frequency in CW, before further button presses worked. I found all announcements were not automatically interrupted by subsequent button presses, and I had to wait for the readout to finish before I could proceed. I was therefore very pleased to learn the lack of readout interruption on frequency changes has been addressed in later firmware releases, and this demonstrates the advantages of the rapid development cycle, and Elecraft’s continued attention to the accessibility issues.

The readout duration may not be a problem if the CW announcement is set to a rapid 35 words per minute, but for slower speeds, the need to wait for the CW readout to complete was occasionally frustrating.

When pressing the band up and down buttons, you will hear in CW something like:

C 1 4 0 1 1

The ‘C’ at the beginning of the announcement shows the Mode is CW.

Note, the Megahertz and Kilohertz are read back, but the Hertz are not. During my evaluation I could not find a way of having the Hertz announced. The button in the bottom right corner reads back the current frequency. You will hear something like:

C 0 1 1

Note, only the Kilohertz are read back.

Direct frequency input is possible, but with the limitation of only the Megahertz and Kilohertz being accepted. As there is no traditional keypad on the KX3, the buttons running along the bottom and the 3 knobs are used for inputting the numbers. This method works, but I found I could not quickly tap in a frequency without waiting for the CW announcement of each previous key press to finish. I understand there is some improvement to the interruption of playing CW readout, but to be totally certain of accurate input it is still prudent to wait until the completion of each number before pressing the next.

In my experience, it is extremely useful for a blind operator to be able to enter an exact frequency. If the person you are in QSO with says they are moving up 750 Hertz, to get away from QRM, it is often easier and quicker to tap in the direct frequency, than to tune with the VFO, and then need to check you have made the correct adjustment by listening to the readout.

I feel the limitation of not being able to read or enter the frequency more precisely than one Kilohertz, is a serious obstacle for a blind operator.

I was pleased to find there was a Dual Watch feature, and both the Main and Sub receiver can be heard in separate ears. The Dual Watch operation is turned on and off from within the menu, and I believe this can be assigned to a Programmable button. There is a 15kHz tuning limit for the sub receiver, in Dual Watch mode, but it is unusual to have a wider spread for DX.

Rob K6DQ has been working on HamPod compatibility, using a KX3 loaned by Elecraft. Rob tells me ‘support for the KX3 is now equal to the K3.’. Rob had to add code for 26 additional menu screens, and the HamPod knows if it is connected to a K3 or a KX3, so it can process queries and commands accordingly. Rob also tells me existing HamPods can be upgraded with new firmware to include the KX3 support!

I would encourage any blind operator to check Rob’s pages at http://www.hampod.com for the latest information.

In summary, the KX3 is very accessible if you read CW, and will no doubt be improved. Congratulations to Elecraft for going the extra mile, and putting considerable effort into accessibility!

From Chris G5VZ, May 2013:

I think it might be useful to readers to also mention the use of the radio with HDSDR.
I started checking this out last weekend and needed to source a couple of leads to
connect the radio up (The interface connectors are a mix of 3.5mm and 2.5mm jacks
with three poles – standard stereo, that is – and four poles.) Having spent an entertaining
time finding suppliers of these odd combinations of plugs and wires I then discovered
that Elecraft part KX3-PCKT is a KX3 connector cable kit with everything you need
to interface the radio to an amplifier, PC, foot-switch PTT and all that sort of
stuff. With these connectors properly sorted, though, I think other software is
opened up – not just the SDR functions using the KX3’s I/Q input and output but also
HRD and the likes. I imagine that’s an accessibility benefit in the grand scheme
of things. And it also demonstrates that Elecraft’s support of the radio is genuinely
100% of everything you need to get it on the air plus their customer service seems
to be faultless.

Comment 2

From Buddy Brannan, KB5ELV – Erie, PA – May 2013

I fully expect things to get even better in regard to the KX3 accessibility. I just love mine! One thing I’ve done, just yesterday in fact, was to set up the programmable function keys to switch between hand key and paddles, and to switch various antenna tuner on/off, AGC on/off, and dual watch on/off in a five-way toggle. If you or any other KX3 users want the macros, let me know and I’m happy to share.

Comment 3

From Chris G5VZ, June 2013:

The menu control of the Morse user interface is essentially through the menu option headed SW Tone. This can be set to none – shown on the display as OFF – when no beeps are generated on any key presses or to ON, in which case button presses are indicated by beep or bee beep and
so on. The other menu settings are CODE and a speed digit-pair; so it’s CODE 10, CODE 15, CODE 20 and so on for feedback at 10 words per minute,
fifteen or twenty. A bit fiddly though. All covered in the original owner’s manual.

If the radio is powered up with the CWT button (Bottom row, button five counting from the left) pressed then the Morse user interface is activated at 20wpm. That is press and hold CWT then press the two power buttons (BAND and ATU TUNE simultaneously) then when the radio powers up release the power buttons first and finally release the CWT button.

This was implemented in firmware MCU 1.26 / DSP 0.99, 10-24-2012 and anything programmed before October last year doesn’t do this. In the current firmware there is a bug and powering up with CWT pressed and Morse UI already enabled can cause the radio to go into MCU Load status. It doesn’t happen every time and, in fact, only happens very
infrequently. This has happened to me once. The way to switch off Morse UI is through the SW Tone menu option.

As far as I know you cannot select or deselect Morse UI using the KX3 Utility Program with the radio connected to a computer.

The current firmware functionality is named “Morse User Interface (Phase 1)” and the documentation suggests that the later phase or phases will include Morse announcements on menu options as well as the button and rotary control operations already implemented.
Elecraft are very receptive to ‘wish list’ emails so anyone with actual experience should
probably get in touch with Wayne at Elecraft if there are specific (And achievable!) ideas for future firmware.

Hope this is useful.
