Radioddity GD-77S and the Sharkk RF OpenSpot 2
An Introduction To DMR by Gena, M0EBP, from a blind person’s perspective!
February 2019
Background
I hope you enjoy these recordings that I have put together after exploring DMR for a few weeks within early 2019. The GD-77S software is V1.1.10, Windows 10 and Jaws 2018..
The zipped bundle is available to download in the Related Downloads section below, and a description of the audio files and some useful DMR links follow:
Apologies for unwanted background noises during recording.
Audio Recordings included in the bundle
001_GD-77S_OS2.mp3
As an introduction Gena describes the Radioddity GD-77S and more.
002_GD-77S_OS2.mp3
Gena opens the software and creates a code plug with just one analog repeater keeping it simple to get started.
003_GD-77S_OS2.mp3
Incomplete! Gena opens GB3PP using the GD-77S.
004_GD-77S_OS2..mp3
Gena adds talk groups to the code plug. TG9 and TG 9999 for the OS2 and TG91 World Wide talk group. Not forgetting to unlink..
005_GD-77S_OS2.mp3
Gena struggles with the OS2 interface using the Chrome browser and Jaws. Hopefully it is clear that important settings should match in the modem and connectors sections of the interface. Remember to save after making changes.
006_GD-77S_OS2.mp3
Gena takes a tour of the code plug and discusses Brandmeister and Phoenix servers and how 2 different numbering systems are linked for UK users.
Additional Files included in the bundle:
demo4-v1.dat
Minimal entries: GB3PP TG 91 WW TG 9999 Echo and TG 4000 Unlink.
Demo6-v1.dat
the UK Brandmeister talk-groups listed below. Unlink is on channel 1 of mode 2. GB3PP and GB3RF are 2 & 3 of mode 2 and are untested as yet.
These are the 2 code plugs observed in this project. Having removed my ID.

Disclaimer:
I am still learning about DMR and while I am glad to share my findings I cannot and do not suggest that my understanding is completely accurate. These are my findings as of February 2019.
Enjoy!
