Well I just finished testing - everything ok except low power on 20 meters.
Decided to adjust bias. Also decided to adjust R111.
R111 10K Pot broke.
I need a new R111. Does anyone know of a source??
Thanks for your time.

Hi John,

Email you address to me, jim (at) HobbyPCB (dot) com and I'll send you a new pot. As for low output on 20M the first two thighs to check:

1. Reset the bias to 150mA per device.
2. Check that the amp's voltafe at the powerpole connectors is 13.8V while it's transmitting, voltage sag is a BIG problem.

If these don't help we can try advanced troubleshooting.

73,
Jim WA2EUJ
