The problem turned out to be a missing wire to carry the RF from the load capacitor to the antenna relay. It goes from above the chasis through a hole to a lead on the relay that also has a RFchoke to ground. I can't imagine why this wire would have been removed, unless it was for some planned modification. Are there any mods that might require removing this wire?

Maybe he was in the process of installing a different t/r relay, such as a vaccuum relay for better QSK/VOX.
