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.
