Amen, Rich!
Been there, done that, got the T shirt!
When 160 meters and WARC is added a whole new ball game evolves.
It is very easy to arc even the heavy duty RF Switch Co. units with just
a single 8877. Some designs get away with non-shorting switches by using
torroids on 80 and 160 meters. Look at the schematics of the big Ameritron
amps to see how the shorting is accomplished using coil stock for all bands.
