[BC] 50 Ohm Load...

Don't forget that you have non-concentric hardware
in the RF contactor. Unlike an FM switch, you no
longer have a true 50 Ohm system throughout. Just
consider all of that as part of the system when you
tune for the optimum sideband rotation at the tx
output terminals. B.E. should be able to provide you
with what the best load is there. It may NOT be
symmetrical at that point!
