With the caveat that I know this is *not* a classic uBITX, and I didn’t see the prior thread where you probably gave more relevant details… so my comments are probably not useful ;-)
I just had a v6 Raduino with a similar issue. 5-8w on cw, ?nothing on SSB. The other telling symptom (which seems different than yours) is that I just had the same level of static, with or without an antenna in rx. ?
Turns out it *appears* to have been a bad sis5351. At least replacing that was the last thing I tried before I could get any output on ssb and RX. All appears to be well after that replacement.?
