I have a Galaxy 919 (IRF 520 mosfet), with a mild tune. It's an exceptionally clean and well cared for radio since it was bought new by me about a year ago.
The other day, I was talking on it, and it just lost power. Checked the power supply, still at 13.8 and checked the power cable for a loose connection and it checked out fine. Checked jumpers, checked SWR, everything is fine.
The radio just blinked off like I'd blown a fuse, but I didn't. I ohmed out the fuse and even replaced it with a good one to make sure.
When the radio loses power, you can turn the on/off switch on and off and the speaker will softly "pop", so the chassis seems to be getting voltage. After you leave it off for a few minutes, it will power right back up and stay on until you key down and talk again. You can key down briefly and unkey, and it will be fine, but the second you actually modulate it will talk for maybe 3 or 4 seconds and it's lights out again.
WTF is going on? I plan on taking it to my tech in a few weeks, but in the meantime I'd like to get some ideas on what I could help him with that it *may* be. I've never had a radio do this. Suggestions?
