Hi Rick:

Acutally, what can happen is not loss of the front end of the
receiver.  The diodes at the AUX RX jack to prevent the front end
from being cooked can blow.  I wanted to point out that the blowing
of these diodes is exactly what is supposed to happen with the
transceiver if large amounts of RF or a static discharge comes back 
through the AUX RX antenna jack.  They are there for protection and 
this is not a deficiency in the transceiver itself.
