During the ARRL 10 meter contest, my ICOM 746 made a loud pop and went 
to black. I suspected the PS. Al K0IJ replaced the regulator in the 
power supply. I started out in the 160 contest, everything OK. Then POP 
and the 746 went to black. oh......!
I sent the radio to Ham Radio Repair Service in TX. The radio was 
checked out OK and returned promptly. 
During the NAQP with the rate meter showing 150 Q's/hour the stuff hit 
the fan again. I reduced power and was able to get back in the contest 
about an hour later. Again running 35 Watts the radio died. I 
reinstalled my backup radio and because the power cord was too short. 
(too many Field Days) I connected to the battery on the UPS system and 
continued at about a 23/hr rate. SNORE!
During my dinner brake, I connected the 746 to the battery and 
completed the QSO party on 160 with about 50 watts. (There is a huge 
difference between the 745 and 746. The 746 has a better receiver, 
built in tuner and CAT connections. )

Now, QST pays off.
While breezing through the February QST there is a tip from K1CHW on 
page 79, concerning his ICOM 706 and a corroded Molex connector to the 
power supply. Check out George's solution. Clean the connector.

I borrowed a Proxy brush from my teeth cleaning tool kit to reach 
inside the connecter and clean the male and female connectors. The 
brush came out black. I finished up with a light application of silicon 
lube, reconnected everthing and the radio is happy again. 

The moral of the story is, if you have a radio with molex connectors,
Keep them clean. A simple cleaning would have saved me about a 100-bucks
S/H and a lot of operating time. 73 Ray
