[ICOM] Icom 706 Mkll G ssb distortion on transmit

[Gary Fiber]

Hi Dave,

Bruce is a good tech listen to him. My own experience i had happen with 
the IC-706MK II previous radio to the MK II G was running mobile, had 
the engine off and was getting some complaints of distortion. I started 
the vehicle and the distortion cleared. Maybe along with what Bruce 
suggested you should check to see if your power supply connections are 
tight up to and including installing new connections and soldering them 
after crimping. Had a VHF Transceiver that was having low power issues 
and the connections though tighter that finger tight, were still the 
problem as the trouble cleared when i tightened up the bonding posts 
using tools. So I changed out the connectors, crimped them on well, 
soldered the connectors and on my power supply it take a 7/16" wrench to 
tighten the binding posts and i made sure they were reasonable tight 
being careful not to snap off the binding posts.
