Ok so the radio powers on but that's it. No carrier on am, nothing on ssb and no receive. I did notice that when keying the mic the tx/rx light doesn't turn red. It just goes out. Also the radio did die on me and then came back to life on its own. The channel display and meter light went out for a few seconds but came back. I'm thinking the tx/rx relay circuit isn't switching? Then I thought maybe the voltage regulator is going? Any thoughts? Thanks in advance.
