Kenwood TS-930S Mods and upgrades

The Kenwood TS-930S - A great classic transceiver from the 80's I purchased from my local club, did some mods to enable the WARC bands, restored AM, fixed the factory cooling issues, fixed the memory backup batteries, replaced the burnt bulbs for the S-meter with LEDs, lubricated the mechanic antenna tuner gears, lubricated top door, and aligned the frequency readout according to the user manuals.
