 The centerpart of the radio station is the [[TD90]] exciter transmitter driving a solid state **SSA 400** power amplifier or a 1000 W power amplifier **SSA 1000** in the embassy radio central; in the embassies, usually the final stage of the 1 kW Siemens transmitter continuied to be used as power amplifier. The centerpart of the radio station is the [[TD90]] exciter transmitter driving a solid state **SSA 400** power amplifier or a 1000 W power amplifier **SSA 1000** in the embassy radio central; in the embassies, usually the final stage of the 1 kW Siemens transmitter continuied to be used as power amplifier.

 The transmitter power amplifier consisting of the final amplifier of the original 1 kW FSK transmitter from Siemens [[S-502]] can be remotely operated. The power apmlifier can be tuned to the 1.5 - 30 MHz range in three ranges: 1.5 - 4/4 - 11/11 - 30 MHz.\\ ​ The transmitter power amplifier consisting of the final amplifier of the original 1 kW FSK transmitter from Siemens [[S-502]] can be remotely operated.
