[Elecraft] Elecraft] [K2] Receiver overload protection

[Steve & Anne Ray]

I got tired of reaching behind to hook up a cable to the aux receiver
antenna input, so made up a cable with a couple of 1N4002 diodes across the
cable from center conductor to ground (cathode end of one diode to center
conductor and anode to the shield and the other diode anode end to center
conductor and cathode end to shield).  This gives a protection as the diodes
conduct at about 0.7 Volts.  I just leave this cable connected to the aux
receiver input all the time, however most of the time I just use the regular
antenna for operating with the aux receive antenna off.
