I'm consulting for a family member on some radio issues and have came to some same conclusions, but I'm not sure if they are the fix, maybe somebody can help me out, not sure if this going to be the right forum for this. They are experiencing the problem with 2 of their dump trucks, they have strobe beacons on the truck that when they flash cause the radio to pop. He says that the ground for the beacon is close to the antenna, I'm thinking it might a proximity issue, the ground being to close to the antenna and might need to be moved. He has replaced the beacon an that is not the problem, the problem lies somewhere with the radio. I've run out of ideas, if someone could help out or point me in the right direction.
Thanks
