?I run wsjtx and a raspi to my QDX and it started having similar problems. I found wspr would tx ok using my laptop but no longer on the raspi, just a brief transmission. Anyway, I found out that must have been after an update on the raspi, the sound card level was running at 153%. As Hans usually says set tx audio to max, I did not discover for a long while that reducing the tx audio level from the raspi back down to 100% cured the problem.
