Well, after two 7QP QSOs, the SB-201 decided to be "playful."

It is keying. Just not putting out ANY power and exhibiting infinite SWR.

The meter will register power going thru when it is in standby, but nothing when it is online.

1800 Volts is OK & abt 90 mA plate current when keyed but not active.

Any suggestions?

The locals suggest cleaning the Tx/Rx relay contacts with a sheet of paper.

Anything else I should check whilst cleaning the contacts?

Sounds like the thing to do.  Harbach Electronics sells replacement relays ($18 if I remember correctly) if cleaning doesn't work.

A bit of paper applied to the relay contacts cleared the problem right up.

Thanks everybody!
