Something is wrong with the SDR firmware or the PA firmware.

works_2020-06-20-2_2020-06-23.png


With this version the transmission on 2m works, but I can no longer tune on HF. :wall:

At first, I thought the tuner had a problem and replaced it with an identical one. But still the same problem. The tuner cant read the Frequency and says "to less power" (MFJ-993b) I downloaded the old software, made firmware update, and was able to tune again.

So honestly dear EESDR team. As much as I appreciate your team and your ideaslike TCI etc, and the forum here, I've felt like a beta tester for a long time. Or is this a game and I get the e-coder after 10 bugs are found?

Please create a test report and check all functions after each software and firmware change. This is your job, not mine. :yes:



And I'm not ready to send it back because I'm sure I would miss something in the future. If it were not an SDR, it would have been with the dealer long ago.

Nominal (PEP) HF output power of the SunSDR2 DX is 100 W.
In SSB mode it might differ from 30 W up to 60 W, depending on the compressor and clipper settings.
The reason for that is peak-factor, it equals 3 for voice signals. TONE signals have constant output power 100 W.
Voice signals with peak power of 100 W have real power approximately 3 times lower. To increase the real power of voice signals use the compressor and other features in the TX processing module, adjust AGC settings.
