I explained what happened and described the symptoms to the folks at Alpha. They were the ones who told me it was likely the main controller board. The "controller" lost its serial port, lost its "memory" of frequency bands, and the timing is off. Without the serial port working, they have to reload the firmware at the factory. The serial port was NOT connected at the time. The Alpha was turned on at the time, along with some other gear, and ONLY the Alpha was damaged. The Alpha was NOT connected in any way to any of my computers. The only connections to the Alpha were the 240V 20A power cable, the RF input and output coax, station ground strap, and the TX line from the transceiver. All of my other equipment, including the FTdx5000mp which was I was operating at the time, continues to function normally, radios, computers, antennas, everything but the Alpha. The result, damage to the Alpha, is surprising to me also. For the $8339 that I paid ( just before the price drop ), you would think the Alpha/controller circuitry would be better protected.
