   One way to partially handle this is to set the squelch tails on the
repeaters to be very short.  Then, install a drop-out timer on the
repeater(s) which will kill the repeater(s) transmitter for a few
seconds about once a minute.
   Adjust the drop-out timer so that the repeaters off time is long
enough so that the jammers HT will time out when the repeaters shut
down.  It won't eliminate the problem entirely, but if the ham signal is
strong enough into the machines input, it'll override the jammer for the
duration of the hams transmission.
   After the QSO ends, the jammers HT will keep the machines locked up
only until the drop-out timer cycles again.   Most repeater users will
put up with the short drop-out interruptions since they will have the
machines back again, at least partially.   Hopefully, the jammer will
see that his efforts are going unrewarded and go away.
