[ICOM] ICOM 706 MK IIG

[Jim Vaughan, K4TXJ]

Hi John,

I also have an Icom IC-706MKIIG.  I have never had any problem with it.
I would suggest that you clean the recepticle on the remote head and the one
on the radio.  Not just the plug on the ends of the seperation cable.
I hope that helps.  BTW, I am not an appliance operator.

73,
