Hi Dan,  Could be the antenna connection or relay, rf amp, or if amp.  Good luck.
Regards, Larry

Hi,  I haven't used my R390 for about 2 years and decided I needed to check
it out compared to other lesser radios I've been using recently.  It's been
sitting there in the best spot in my radio area and other than hooking up
the speaker it should have been ok.  It was still set on 80 meters where I
used it last but when I turned it on it was more or less dead except I could
tell the audio was working but no indication of signals or ability to peak
noise.  I finally went down to the broadcast band and was able to tune in
the three strongest local am stations between 600 and 1000 khz.  The
Megacycle change knob seemed to be the key to getting it to work and it was
very sensitive to position  and would become alive by moving the Mhz change
knob slightly.  And it sounded ok but I think the signal level is somewhat
low on the meter compared to what I remember for the one station that I
listen to the most at 960 khz.  And it  suddenly goes dead  occasionally
when I'm not touching the set but is revived by more or less moving the
megacycle change knob slightly.  I tried the higher bands but could get no
response on any band despite a lot of motion on the Mhz change knob.  Is
there one particular switch that is the likely culprit?  This radio has been
pretty reliable in the past after I worked it over quite a bit after getting
it 10 years ago but I don't recall having any problems with switches back
then.  I have the manuals but thought there might be something obvious that
others have encountered.  Thanks,  Dan
