[hpsdr] Distorted audio

Hmmm...  I've just turned on my HPSDR kit for the 1st time in about a month and was horrified to hear a very distorted audio output. CW signals sound like T4/5 report.

I haven't yet 'scoped the 13.8V line or the various O/Ps from LPU but everything seems to be working except Excalibur has lost phase lock with the Trimble Thunderbolt reference and no amount of tweaking the trimmer on X1 will pull it back into lock.

Any ideas?
