[Amps] one question test for hams

Also, broken wires, physically broken components including switches, broken traces on circuit boards, corrosion, and a number of other things.  This is especially true of units used for mobile operation.  Vibration, "bumps" in the road, and other situations definitely cause failures in mobile equipment that have absolutely nothing to do with heat!


Having spent many decades in the commercial two-way radio and microwave radio arena, I have seen a LOT of equipment failures that had nothing to do with heat!
