+ | |||
+ | Still according to the doctrine of use from the twenties / thirties, the wireless station was designed on a single axis trailer to be pulled by another vehicle, it got the nickname „vegetables trailer“ from a kind of trailer used by vegetable farmers. | ||
+ | |||
+ | If mobile use on a trailer was impossible, for example if the station should be operated in a bunker, a command post or on a hill or mountain top without an access road, the station with the same components was used as [[SE-215|Tragbar Schwere Funkstation]] [[SE-215|TS40]] („Heavy portable station 1940). Nearly all accessories were included, in favour of the troop which had to carry the station, the DF antenna for the receiver and the 10 m telescopic mast was omitted. | ||

+ | * [[Frequency Range]]: 190 - 715 kHz; 1.5 - 4.5 MHz | ||
+ | * [[Sensitivity]]: | ||
+ | * [[Output power]]: [[A1]] 100 Watts, [[A3]] 25 Watts | ||
+ | |||
+ | ==== Power Supply ==== | ||
+ | * Petrol operated or electric motor (220/380 V) to drive a 50 V / 150 Hz three-phase generator. | ||
+ | |||
+ | The station was 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 and a solid state rectifier to generate the plate voltage of 120 V and heaters voltage of 6 V of the receiver and the accumulator charger. | ||
+ | |||
+ | An inverter is used to generate the plate voltage of the receiver [[E41]] from the heaters accumulator power of 6 V, when the generator of the transmitter was not in use, or for remote control of the station. | ||

+ | ===== Operation ===== | ||
+ | [[se-300-stationmaterial|Here]] find an overview of the components of the **Mobile Light Radio Station 40**. | ||
+ | |||
+ | ===== Technical Principle ===== | ||
+ | The station receiver [[E-601|E41]] is a battery valve all-wave receiver; at frequencies below 12 MHz, it acts as [[single conversion]] set and above 12 MHz as [[double conversion]] superhet; the frequency band selection is done with plug-in coil sets, similar to those found in the [[E-610|HRO]]. | ||
+ | |||
+ | The matching transmitter [[S-300]] is housed in an almost " | ||
+ | |||
+ | The transmitter covers longewaves 190-242 / 242-400 / 400-715 kHz and three shortwave ranges 1500-2300 / 2300-3300 / 3300-4500 kHz, a calibration crystal is used to calibrate the transmitter on 4000 kHz. | ||
+ | |||
+ | ==== Valve Layout ==== | ||
+ | Refer to the pages of the components. | ||
+ | |||
+ | ==== Development ==== | ||
+ | In 1938, there was an invitation of tenders to develop a " | ||

+ | 98 units of the " | ||
+ | |||
+ | ==== Field Use ==== | ||
+ | The 98 station were delivered 1939/43 and were used for command communication until 1958, the equipment was liquidated in 1971/72. | ||
