S 406 Technical Page - 2
Frequency range: 3,750-15,000 kHz, switchable in 10 steps continuously tuning. The wave bands switching was made by temperature-compensated capacitors.
The frequency-determining components are stored in a ceramic housing. For the tuning, a strong silver-plated ball variometer is used.
Valve (tube) line-up: 2 valves REN 904 (exciter), 2 valves RS 288 (splitting stage), 2 valves RS 291 (PA), 1 valve RGN 1064.
Power provisioning: Converter TFG 110/3 + TFG 412/7
Accessories: Power supply unit Spez 2157/S, frequency control unit K 150 S2/36.
A1: Telegraphy without modulation by periodic oscillation. Short CW.
A2: Telegraphy by on-off keying of one or more periodic oscillations low-frequency amplitude-modulating the emission, or by keying of the emission modulated by those oscillations. (Continuous signal of an emission amplitude-modulated by low-frequency periodic: e.g. some radio beacons). Sounding CW.
