The easy way to protect the RX only front end is to shunt the receive only
jack externally, with two switching diodes connected polarity reversed.
I.C.E. uses this config. successfully in their preamps.
IN914/4148 type, 75piv diodes were available a year ago from Radio Shack at
10/$1.50. I believe these shunt at 1.7 volt and they seem to have no effect
on weak signal performance, when inserted in the coax lead-in system.
