[ICOM] 756ProII Resets on Transmit - Fixed Again

[Gary Fiber]

Frank,

Its not as uncommon as you might think. I had a GE-MVP doing 9600 baud 
packet. It generally did 35 watts out and one day I found it at about 20 
watts. All sorts of things ran through my mind. Finally I tightened the 
power supply binding posts with some pliers and it jumped right up to 35 
watts again. The binding posts were tighter than finger tight but 
apparently loose enough to cause a high resistance point and voltage drop 
to the MVP. After finding that I removed the power leads, crimped some new 
ring connectors on and soldered them. Got it good an tight when I 
reinstalled the power leads and did not have a problem again.
I think heating and cooling of the terminals is probably the culprit. The 
binding posts expand and contract a wee little bit but over time things loosen.

We all tend many times to over look the simple stuff and think some deep 
buried problem has rose up to bite us. After as many years in radio and 
over 100,000 phone calls while working at Icom, like you might have made 
for this trouble, I still do it my self.  Good Find and enjoy the rig.
