Chuck -
Clean the relay contacts in the T-4X. Wet a piece of good paper with
DeoxIT, (or alcohol,) slip it between the contacts and close them with
your finger and draw the paper out. If that doesn't clear it, let us know!

OK, here's one...
This has happened intermittently before, but now seems to be happening
more consistently.
T4X / R4A - turn them both on, R4A working fine, good signal strength.
Key the transmitter (key or mic), after which signals disappear in the
R4A. You can just about hear them down in the mud, but essentially gone.
Doesn't make a difference whether transceive set to RX or TX or Separate.
Nor doesn't make a difference whether set to external mute or not.
One time it happened, I keyed the mic for a second, and the RX was OK
again.
Now doing that isn't helping.
For a few times I thought the band was disappearing on me, but now I
know that's not it.
Guess I'll dig out the T4X schematic and check that switching.
