for the response Luke, and Phil also.<br>

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. <br>
<br>
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. <br>
<br>
I'll try Phil's suggestion and do an upgrade of PowerSDR and a
full database reset.<br>
<br>
Merry Christmas to all on the list and thanks to all the
developers for their hard work - much appreciated!<br>

<div>The following may be stating the obvious, but sometimes

<div>Note that the pins on J6 go towards ground when
activated, so these need to be connected to the ground side
of your relays, there needs to be +12 V on the other pin of
all your relays for this function to operate. Also, the
“External Control” (button on v3.3.9) must be selected to
activate or set up the OC feature.</div>
