I have used this rig in the honda for several months without a hitch. I took it out to have some adjustments done and reinstalled it nearly exactly as it was. I tested it in the drive and everything worked, the two meter side was fine, the antenna tuner, everything was right. This afternoon, I hop in for a short trip and I'm finding that when I transmit in two meter FM mode, the rig shuts down briefly and restarts itself. Now, here's the puzzle. It doesn't do that with the motor off. It doesn't do it in SSB so I'm thinking that SSB does not draw full amperage 100% of the time, so now that I'm thinking, I should have tried it in CW MODE, I'm thinking amperage draw, but, arguing with myself, I tried turning the FM power down to about nothing.... And that didn't change anything. Sooo, I think, SWR? Amperage? I'm puzzled, I've never seen this.... The 2meter antenna was in use while the yaesu was out, i had a 2meter mobile there... It worked great... What am I missing?
