[Mobile-Portable] Distorted transmit signal from Icom 706 MKIIG

[K7fe at aol.com]

You are experencing RF feedback.  The Icom 706 remote cable may be  tamed 
with ferrite beads (clamp on) over both ends of the extension cable.   I also 
needed to add them to my coax at the radio (about 3") and antenna  (about 12" of 
beads), plus several on my external DSP speaker wires.  My  mobil rig is 
described on the QRZ.COM call sign lookup profile.  I run  about 1100 watts out on 
HF Mobil.
