 In contrast to the transmitter of the [[SE-300|FL 40]], the frequency bands are much higher: 300 - 380 / 380 - 600 kHz and 3000 - 5330 / 5330 - 8000 and 8000 - 12000 kHz, the frequency of 8000 kHz can be calibrated with a luminous crystal. In contrast to the transmitter of the [[SE-300|FL 40]], the frequency bands are much higher: 300 - 380 / 380 - 600 kHz and 3000 - 5330 / 5330 - 8000 and 8000 - 12000 kHz, the frequency of 8000 kHz can be calibrated with a luminous crystal.
  
-The transmitter has three stages, a [[EBL21]] in the oscillator / exciter stage, two [[EBL21]] in frequency doubler stage and two [[OS41/​1250]] in the power amplifier stage. Operation modes are A1 (CW), A2 (modulated telegraphy) and A3 (telephony);​ the modulator stage ([[EBL21]]) acts on the grids of the power amplifier stage. The output power is switchable, in position „Einpfeifen“ ("​tune"​) / „Low“ it is 5 - 7 Watt, in position „Medium“ 20 - 30 W and in position „High“ 80 - 120 W.+The transmitter has three stages, a [[de:EBL21]] in the oscillator / exciter stage, two [[de:EBL21]] in frequency doubler stage and two [[de:OS41/1250]] in the power amplifier stage.

-The plate voltage of 330 V in the exciter / modulator stages and 1200 V in in the power amplifier stage is generated from the three phase 50V / 150 Hz voltage via a transformer and four [[PV 200/600]] rectifier valves.+The plate voltage of 330 V in the exciter / modulator stages and 1200 V in in the power amplifier stage is generated from the three phase 50V / 150 Hz voltage via a transformer and four [[de:PV 200/600]] rectifier valves.
