I purchased the radio with this symptom. ?Everything seems to work for VHF/UHF. ?This means the driver is functioning. ?When I trace the HF signal with a scope past the driver I do see a signal that varies with the power adjustment. ?This indicates to me that the ALC is functioning. ?The finals were removed and checked good with a transistor checker. ?The HF signal through the driver output seems to lose amplitude down the path through the finals and is negligable at the antenna connector. ?All this through a power meter and a dummy load. I would appreciate any suggestions or help to diagnose the problem.
