Got the radio cheap, it was working fine then while on am mode rx dropped out. If I switched to ssb I had rx and if back to am rx would work until I key up again for more than two seconds the am rx would fall out. Its not stuck on TX just like between rx and TX. Now the am rx won't work at all but ssb rx is great and TX on both am and ssb is good. Any ideas? Its got a new relay in it btw...
