[Elecraft] Dual Receivers 2 different antennas Diversity receive

[John K9UWA]

You could use a device such as the KD9SV  FES "short for Front End Saver" The 
Device removes and grounds the receive antenna input during transmit. Yes it is 
fast enough for QSK. You can also run your PTT line to your amplifier through this 
device. If the Device fails to work that prevents the amplifier from being keyed.
