{Collins} KWM-380 does not transmit or receive

Working on a KWM-380 that at first blew fuses an found shorted tantalum
capacitors.  Now it all comes up, all controls work but nothing comes in on
receive and it doesn't transmit.  Audio amp works and I can hear filter
change effects.  I get 3 beeps when I turn on. Any suggestions as to where I
should look first?  I suspect that it's something shared for transmit and
receive paths.  Thanks.
