[ICOM] RE IC 765

[Larry Winslow]

Hi Jim,

My 765 started acting exactly as you describe. 
The fix cost zero bucks but does require some 
digging into the insides of the rig.

There is a current limiting resistor in the power 
supply of the radio. It consists of a bar of 
copper about 1.5" long and about 1/8" square. The 
fix consists of resoldering it on each end. One 
thing to be careful of is to not solder beyond 
the small hole drilled in each end of the bar. If 
I remember correctly, the power supply is 
accessible from the bottom and is located on the 
left side with the front of the rig facing you. 
Also, it's buried under another circuit board.

It was a bit of a chore to gain access to the 
power supply but once there the fix was quick and easy.

PS: Icom has a trouble shooting section on their 
web site and the fix is described there.
