[hpsdr] Penelope J6 Open Collectors on TX

[n3evl]

Thanks for the response Luke, and Phil also.

I think everything is OK from the config in PowerSDR all the way to the 
LPF board in question - the OC outputs work just fine in RX mode - it's 
only the TX config that seems to be ignored.

I ran another test yesterday with 12V going to the LPF and the OC 
signals coming from Penelope - nothing else in the amp was in the 
picture.  In this mode, the band selection in RX was fine - I can hear 
the selected relay bank click when I change bands. As soon as I hit MOX 
or Tune in PowerSDR, I hear the relay click again as the relay for the 
selected band turns OFF.  Go back to RX and it clicks again, back to 
selected again.  So everything points to the OC pins for TX not being 
used at all despite having the same pin mapping in the matrix.

I'll try Phil's suggestion and do an upgrade of PowerSDR and a full 
database reset.

Merry Christmas to all on the list and thanks to all the developers for 
their hard work - much appreciated!

73, Pete, N3EVL
