[Icom] Icom 706 MKIIG CW contest observations

Mon, 27 May 2002 17:49:44 -0500

I use the 706MKIIG in both phone and CW contests.  I have 500 Hz filter
only.  I agree with your findings, except I think the differences in band
noise are more due to condx than the rig.

Only complaints I have are the finger hole in the tuning knob is too
small for my fingers, and it is a pain to go into the menu to change CW
sending speed.  Of course, if you use any kind of an external keyer
(computer, stand-alone, etc.) it don't matter.  I also use a LDG AT-11MP
autotuner, really a great help when changing bands.

Only complaint I have with the rig is bad diode(s) in then SWR bridge. 
K5RWS tipped me off to the problem.  ICOM fixed it immediately under
warranty.
