Ive been trying to diagnose a strange problem with my DX 959. On AM when trying to check my SWRs I key the mic, it swings up to about 5 watts on the power meter and then instantly drops to zero. Ive tried using the AM Power VR-? to lower the wattage and no matter where I try to set it, when I key up it goes to a certain point but then instantly falls back to zero. Ive been told this means that something is wrong with the AM Carrier but am unsure how to diagnose which part of the radio is causing this issue or which components to start testing for failure.
Has anyone ever encountered this problem or know how to start diagnosing what is causing it. Thanks!
