[hpsdr] Penny V1.4 firmware issue (tracked down problem but not sure where to go next)

[Paul Fletcher]

OK so here goes.

Hardware config:

J6 Metis
J5 Excalibur
J3 Mercury
J1 Penelope/Pennylane

No external PA and Alex also installed.

Firmware Versions:

Penny or Pennylane V1.4
Mercury V2.9
Metis V1.4

Software versions:

Latest version of PowerSDR 1.19.3.4 and 1.19.3.5 plus latest Unified version 
KISS Console.

Observation:

Whichever software I use the TX audio is distorted and noisy and low in 
level too.

Step 1 of test:

Revert to an earlier version of PowerSDR that will allow me to run V1.3 of 
Penny[lane] but WITHOUT changing the Penny[lane] firmware.

Result - same distortion.

Step 2 of test:

Revert to Penny[lane] V1.3 with earlier version of PowerSDR and current 
version of KISS console.

Result - audio is clean again on both programs despite KISS console 
complaining it can't find Penny.

So there is something about my setup that causes an issue with V1.4, there 
is a bug in 1.4 or there is another variable I haven't looked at. The 
difference is in no way subtle and exceptionally audible.

The problem I now have is the latest versions of PowerSDR insist on V1.4 
firmware so I'm stuck to know what to do.

Regards,
Paul M1PAF
