Gary,?
Have you tried checking the Terminal Application sweeps? If so how do the bands look? The RF Filter sweep will be the most telling.?
A nice matrix of cathode voltages has been posted here and I can't find it at the moment. I'm going to try and recreate it here:
? ? ? ? ? ? D1? ? ?D2? ? ?D3? ? ?D4? ? ?D5? ? ?D6
80m? ? ? L? ? ? ? H? ? ? ?H? ? ? ?L? ? ? ?H? ? ? ?H? ? ? ?
40m? ? ? H? ? ? ?L? ? ? ? H? ? ? ?H? ? ? ?L? ? ? ?H
30m? ? ? H? ? ? ?H? ? ? ?L? ? ? ? H? ? ? ?H? ? ? ?L
20m? ? ? H? ? ? ?H? ? ? ?L? ? ? ? H? ? ? ?H? ? ? ?L
L or Low is ~0V
H or High is around the voltage you built your kit for.
These are from my QDX testing and I'm almost sure they agree with what's been posted.
The measurements are made while in the terminal program in the RF Filter Sweep test.
You may need to reflow the diode connections.
Hope it helps!
