OpenGD77

Because of a major problem with the Tx Power level on the RD-5R, I have released a new version for all radios.

See

https://github.com/rogerclarkmelbourne/ ... /R20200503

The other major update is the inclusion of DCS support, thanks to KC7RBW, as well as some other GUI enhancements (by Daniel F1RMB), and also some bug fixes by me.

See the release change log on the Github page.


Note.

The power output on the RD-5R version is still far from correct, but it should no longer be overdriving the PA.

As things currently stand, I don't think there is any likelihood of the Tx power calibration being fixed on the RD-5R.

I simply don't have the time to take my RD-5R to pieces, and solder wires to the C6000 and AT1846S in order to reverse engineer the data being sent to these chips, in order to understand why the power output is so wrong.

And the last time I was in contact with Dzmitry EW1ADG, who ported the OpenGD77 to the RD-5R, he was in lockdown, and didn't have any access to anything like a logic analyser or a scope etc

I will contact Dzmitry again, and alert him to this major problem with the Tx power level, but I think it could be many months before he is able to investigate the problem.

Thanks Roger ( & Daniel)

thank you all

Something weird with the latest version of this day on one of my 3 GD77s:
No melody on starting.
No keypad beeps.
No sound at the start and at the end of the broadcast
In FM by opening the squelch, there is normal sound.
In DMR parrot, the server responds but no sound, by calling, no one answers.
Back to the version of April 30, everything is OK, re switch to version May 3: same problems ....
The other two GD77s work fine with the May 3 release.
Here it is

Sounds weird. Did you tried to reset the settings ?

Cheers.

Hi Daniel, a reset setting and it's ok, strange that only one GD77 is affected.

I found again the problem , and resolved it.
If the volume of the keypad beeps is set lower than +3db, no sound.
I already had the problem few month ago and the next update removed it at the time.

I also confirm that in the RD-5R after switching on there is no characteristic melody, moreover, I cannot hear the correspondent talking, although it can be seen on the screen that he is in communication. Turning the radio on and off repeatedly will sound up, but not every time.

In GD-77 I ​​have the same problem with sound, only setting the sound level + 3dB solves this anomaly.

I had the same audio problem on my 3 gd77s changed the setting to +3db and all worked then set it back down

Thanks Roger, Daniel & Team

The release works flawless with my GD-77
