G4WIM 24cm ATV Transmitter (1994)
In the early 1990s, activity in the 23 cm amateur radio band (1250-1300 MHz) soared due to the arrival on the market of wideband RF power amplifier modules that allowed easy generation of transmitter power levels in the watts range. Most of these units were Motorola and Mitsubishi made and originally designed as drop-in power amps in base stations of 800/900 MHz cellphone networks which were rolled out at a terrific pace at that time.
