One solution to the receiving problem when using high current relays may be to have dc current (eg 100mA) pass through the contact in RX. This would be particularly easy to implement when the antennas are zero ohms at DC because the dc current source can then be placed in the shack (with a suitable choke to isolate the RF from the supply and capacitor to isolate the DC from the rig).
