I have a K3 approx 8 years old. Fully equipped with subrx, 100W PA, antenna tuner and in/out module.
When I connect the subrx, the main rx sometimes loses signal and at the same time power out goes to zero. Looking at the diagrams, I suspect there is an intermittent contact problem in relay K1 shown on the SUBIN schematic. This relay is responsible for sending antenna signals to the splitter when using the subrx and also connects the splitter output back to the main rx. The same contacts on the relay is also a path for the low level tx signal. An intermittent contact on this relay and particularly contacts 3-4 could explain the behaviour I see. Has anybody experience relay failures and if yes have they managed to change out the relay? Sending the K3 back to Elecraft is not a preferred option as shipping charges to/from Norway will be fairly expensive.
