[ICOM] No power out on my 7600

[Phil Krichbaum]

JK,
    All my antenna grounds are 100 ft away from the shack and also on 
the various towers before the coaxes run on the ground to the WX0B  
STACK Match and SIX PACK switches out 100 ft from the shack and two 1/2 
inch hardlines bring the various antennas into the shack after some  
lightening arrestors on towers. I do not ground the rigs and amps in the 
shack.
