Looks nice already. I also want to test the alpha version.
I need to know which hardware version your radio is, and also your DMR ID number.
Also do you have the official firmare for your radio in case you need to go back to the official firmware.

There are many versions of the official firmware.
Hardware version is V02.01
DMR ID:2060289
I have all the original firmware versions of the 9600 available

Anyone testing the MD9600 version

Please can you try this new CPS version

https://www.opengd77.com/downloads/Publ ... .02.01.exe

There is a new menu which allows selection of GD77/GD77S/DM1801/RD5R, or MD9600

This replaces the functionality which required the shift key to be held down

Thanks for the email Roger. I am now using the OpenGd firmware on the 9600. the first impression is fantastic. We will continue testing.

To all testers

Currently I think there may be a problem with DMR Tx 4FSK deviation level.
Several people reported that the BER is high when using Duplex Hotspots.

Its also possible that the factory frequency calibration is not very accurate.

At the moment the OpenGD77CPS is not compatible with the MD9600 calibration data, because it is a completely different format to the GD77.
So the only way for operators to calibrate the frequency is to reload the official firmware and uzs the official CPS to make changes


Also on DMR Rx, some radios have clicking.
Colin just sent me a possible fix for this, which I need to test.

Note.
The key mapping is definitely a problem, P1 as SK2 is currently not fully working , nor is P2 for SK1.

Personally, I would prefer to us the front pansl rotary control always for Up/Down, and the Arrow keys (Up / Down) on the front panel as Left / Right

But I know some people prefer the existing mapping.

I will probably make a new setting / option to allow the operator to select between these 2 ways of using the front panel Rotary control and Up/ Down buttons

V2 hardware DMR modulation problems at low power levels

Post by VK3KYY » Sun Jan 02, 2022 10:32 pm

FYI.

MD9600 hardware version 2.x have known DMR modulation levels on low power settings.

This seems to be most noticable by people trying to use these radios with hotspots.

Anyone experiencing these problems, should try using higher power levels to see if it fixes the hotspot BER problems.

Hi,

Just to mention, the Retevis RT90 is the same beast as the TYT MD-9600, it just uses different version numbering.


Cheers.

Fun fact, but currently not too relevant: hotspot mode works fine. :)
