[600MRG] K3 owners

[Ken Roberson]

I'm using the Elecraft W2 watt meters alarm output to enable pin 7 of the ACC to inhibit
the TX on the K3, if the SWR gets to a per-set level , I had to install a pull-up
in the W2 .  If that ugly SWR goes up in the middle of the night this will
save the MOS-FET.    73 all Ken WG2XXM
