I posted this over on the Zed. Thought I'd cross post it here to see if anyone could help diagnose it as I know a lot of you dont do the zoo. Thanks for reading
Hi. I have an Icom IC-706mkiig that has been sitting on the shelf for several years. About 8 or 9 months ago, I brought it down and hooked it up to an antenna and powered it up. It received OK for several minutes then the receive quit. I didn't try the transmit as the antenna wasn't tuned at that point. Once the receive quit, I tried looking at my coax and antenna to see if that may be the issue.
The coax works ok. Tested it with continuity tester. No shorts or anything out of the ordinary. Tried the coax on another piece of gear and it worked fine.
The antenna was a random length long wire. nothing special.
The power supply is ok. had a friend with better gear then I check it but I don't remember what his readings were. Only that he said it was working OK
While the rig was receiving, I was getting good signals, atmospheric noise etc. Then it just quit. The radio powered on but nothing. just a light hiss thats the usual for a receiver not hooked to an antenna. The screen came on and I got the everything thats supposed to be there. I repowered the radio several times and couldn't get the receive to come back on.
I put the radio back on the shelf for a few months then I brought it back down to take another look at it. Did the same thing. Hooked it up to power supply and antenna and the radio powered on OK, The receiver worked ok then after several minutes it just quit again. Once again, I put it on the shelf and after 3 months, tried it again and got the same thing.
Anyone have any idea on what might be the problem? The fact that it receives then quits and receives again after a long period of power down i think is a clue but I cant figure it out. Google is no help.
I'm planning on sending it to a repair guy but I thought I would drop a message here to see if anyone has had the same thing happen with their rig. I'd kind of like to be able to give the repair guy a few ideas so he has a place to start. Is there anything simple I could try before i spend some serious $$$ on getting it fixed?
Thanks
