Re: sBitx No Power Out, blown Finals?
|
Here is some feedback,
in the last 3 weeks there was a lot of email traffic with the support of hfsignals. I have made several videos on request from the behavior of the
TRX to measurement setups to show in the video how the quiescent current is and what happens during transmission.
?
Today I was told to desolder the MOSFETs by chance, you don't know exactly where the error could be and install the supplied ones myself because I contacted them 3 days after the warranty expired.
?
The error was noticed for the first time 14 days after receiving the device, 1-2 times no transmission power at approx. 50 FT 8 QSOS in 4-5 days.
A week later I started up again and everything worked normally again, 4-5 days later the same error, out of 100 transmissions 2-3 times no power - of course I first redid the software,
opened the device at the weekend to look for faulty areas, reassembled everything and retested, the device then ran for about 1 week without problems and then the error
was there more often, at that point I turned to the forum here and at the same time to HFsignals
?
and now I'm told because I got in touch 3 days too late it's not a warranty case, that's kind of frustrating so next time, as soon as even the smallest error occurs in our
experimental hobby, write to support immediately and never try to solve it yourself.
