Release 3rd May
Posted: Sun May 03, 2020 10:21 am
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.
