SE-300: Mobile Lightweight Radio station 40

Technical Data

Here you find an overview over the complete station equipment of the SE-300:

Frequency Range: 190 - 240 / 240-400 / 400-715 kHz as well as 1,5-2,3 / 2,3-3,3 and 3,3-4,5 MHz
Analog dial, dial accuracy 1‰
Modes: A1, A2 (900 Hz), A3
Output power: A1 100 Watt, A3 25 Watt
Power supply: The transmitter is powered by a petrol or by an electric motor coupled to a three phase generator, which provided the necessary 50 V 150 Hz voltage. A rectifier unid was used to generate the plate voltages of 1250 and 300 V for the transmitter.

Frequency range: 100 kHz - 60 MHz in ten ranges, Plugin coil sets for bandswitching, on the coil sets a printed coarse frequency dial.
Principle: Single / double conversion, IF 70 / 465 kHz
Modes: A1 with BFO, AM (A3), SSB (A3J with BFO
Sensitivity: AM (A3) / Selectivity: „wide“ ± 3.5, „medium“ ± 2 kHz, „narrow“ 100 kHz.
Power supply: 120 V plate voltage and 6 V valve heaters from the rectifier oder inverter; as an alternative the set can be powered from a separate inverter for the E41

Power supply: The rectifier is powered from the generator with a three phase voltage of 50 V, 150 Hz.
Connection to transmitter („zum Sender“): Plate voltage 1250 V for the transmitter output stage
Connection to transmitter („zum Sender“): Plate and auxiliary voltage 300 V, auxiliary voltage 50 V, 150 Hz
Connection to receiver („zum Empfänger“): Receiver plate voltage 120 V, receiver heaters voltage 6 V
Connection to inverter or accumulator 6 V („zum Wechselrichter 6 V oder Akkumulator 6V“): to power the inverter with 6 V or for charging the acccumulators.

to be used to power the receiver when the generator is not working, in stations No. 1 - 20 for traffic and for remote operation of the receiver.
Connection from the rectifier („vom Gleichrichter“): Voltages and and sidetone
Connection to the accumulator („zum Akkumulator“): 6 V, when the rectifier is working to charge the accumulators, when the rectifier is turned off to power the receiver from the accumulators.
Connection to the receiver („zum Empfänger“): Plate voltage 120 V and heaters voltage 6 V to power the receiver.

to power the receiver when it's used independently from the transmitter, if mains current is available
Connection to the rectifier („vom Gleichrichter“): Voltages and sidetone
Connection from the rectivier („v. Gleichrichter“)
Connection to the accumulator („zum Akkumulator“): 6 V, when the rectifier is working to charge the accumulators, when the rectifier is turned off to power the receiver from the accumulators.
Connection to the receiver („zum Empfänger“): Plate voltage 120 V and heaters voltage 6 V to power the receiver.

The generator provides the necessary Three phase voltage 50 V, 150 Hz to power the Mobile Light Radio Station.
The generator can be driven from a petro or electric motor, according to the available power source, the petrol or electric power is connected to the generator. The electric motor can be powered from mains 220 V, from three phase mains 3 x 220-350 V or from three phase mains 3 x 380 - 500 V.
the three phase voltage 50 V 150 Hz from the generator is fed to the rectifier via the connector „zum Gleichrichter“ and to the accumulator charging unit via the connctor „zum Ladegerät“.

The accumulator charger is powered with three phase voltage 50 V 150 Hz from the FL40 station generator.
It can be used to charge the stations 6V accumulators with different charging currents.
On two instruments, the charging voltage and the current is displayed.
There is a compartment with a bottle of destilled water and an areometer to control the concentration of the accumulator lye.
