I have installed my S9-175 in my pick up and am experiencing a very minor burn from my RK 56 and ST 65 mics, The antenna (102 whip) is on a very well grounded mount bolted through to the frame using two of the the factory box bolts, Box is bonded to the frame on all 4 corners as is the exhaust in 3 places. SWR is 1.2 on 1 and just moves the needle on the Vanco enough to say it moved but not enough for a reading on 40. I have upgraded the coax from pro trucker RG8XX to Tram low loss double shielded and that helped a little. Radio is wired with 4 AWG directly to POS and NEG of the battery. I'm out of ideas and need help. Anything over 3/4 power and the burn really starts to get noticeable Any ideas?
Thanks
