Don, The suggestions did not fix my issue. All solder joints were redone and I checked everything with a magnifier light. Relay K2 works fine. I checked it on 80m where the RX is fine. I checked the bottom of the main board and all is well there too.
When I switch bands to and from 160, I can see a small blip on my old analog VM from pin 16 to GND. I see a similar blip when I turn off/on the RX antenna using pins 3 and GND. Any further thoughts? 73, Mark K2QO Quoting Don Wilhelm <[EMAIL PROTECTED]>: > Mark, > > Well, if relay K1 does not switch, you will not have any output on > 160 > meters - but you also said that it does not receive on the Rx > antenna > either - so relay K2 must not be working either.
