[R-390] Break In Operation of R-390 & CV-591 Converter

[David C. Hallam]

Has anyone had any experience operating break in with the R-390 and & CV-591
converter.  My set is not fully muting when the break in relay is activated.
I can hear the relay(s) pull in and the audio output from the CV-591 drops
but I can still hear the station so I gather there is still RF getting
through the antenna relay.  Is it just maybe dirty contacts on the antenna
relay, or is there something else I need to do?
