I built a switch unit using a Dow coax relay and it's outside contacts to swap key and amp switching. Was not totally convinced regarding isolation.
I rebuilt using a Radial transfer relay allowing the input to the out of circuit radio to be grounded. Admit this is better if the relative S meters are telling the truth but I confess to remaining a tad concerned and now switch the unused rig to it's second antenna position which reduces crosstalk further.
