+ | ====== SE-401: Motorized Wireless Station 44 ====== | ||
+ | **Motorized Wireless Station 44**, **M44** resp. **SE-401**; developed and produced [[Zellweger, | ||
+ | The [[Zellweger]] Company, based in Uster, did develop the **Funkstation Kurz Lang 43** (Short Long Station 43) based on the components of the [[SE-300|FL40]] (Mobile Light Station 40) in the years 1943/44 to replace the Telefunken Short- / Longwave Station [[SE-217|Kurz - Lang - Station / D-Station]], | ||
+ | |||
+ | Now, the call for a motorized radio station was heard at [[Zellweger]]. In fact, the [[SE-300|FL40]] was mobile, but a separate vehicle was needed to tow the trailer. So [[Zellweger]] developed the **Motorized Radio Station M44**.\\ | ||
+ | The components of a standard [[FL40]] were installed in similar steel tube frames and with similar auxiliary equipment like in the KL43 in a light truck; In contrast to the KL43, the station was equipped with a crank mast at the rear of the truck, like the one found on the [[FL40]]. | ||

+ | ===== Station Material ===== | ||
+ | The **Motorized radio station 44**, abbreviated M44, is a wireless station built into a Berna truck. It consists of the transmitter and receiver components of the FL40. Thanks to the power supply from a built-in car generator and the roof antenna, the station can be operated while driving. | ||
+ | |||
+ | The station is quite similar to the [[SE-218|Short-long station 43 / " | ||
+ | |||
+ | The **transmitter** is the reliable [[S-300|FL40 transmitter]], | ||
+ | |||
+ | The frequency ranges 190-240 / 240-400 / 400-715 kHz in the longwave range as well as 1.5-2.3 / 2.3-3.3 and 3.3-4.5 kHz in the shortwave range are covered. By means of a quartz crystal, the transmitter can be calibrated on the frequency of 4000 kHz. | ||
+ | |||
+ | The transmitter has three stages, a [[de: | ||
+ | |||
+ | 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. | ||
+ | |||
+ | **Receiver** is the proven [[E-601|Uster / E41 All wave receiver]], but only the 200 kHz - 24 MHz ranges are covered with seven coil inserts. A station clock is mounted to the right of the frequency coil. | ||
+ | |||
+ | The truck Berna CR1D is equipped with a 65 hp four-cylinder diesel engine and with the built-in wireless station, it has a weight of 5070 kg. The vehicle is equipped with a three-piece L - roof antenna to operate thestation on the move. For shortwaves, a 14 m crank mast Magirus, similar to the one found in the [[FL40]] is used, and for fixed operation for shortwave a 8 m and for longwaves 50 m long wire antenna between two 10 m masts is used. | ||
+ | |||
+ | As with the [[FL40]], the power is supplied via a gasoline or mains motor-fed converter group, which provides the 50 V / 150 Hz three-phase current. During driving, the converter is fed by the car generator. | ||

+ | ==== Einsatz ==== | ||
+ | Als Einzelstationen waren die vier Stationen M44 der Leichten Kompanie der Funkerabteilung 6 bis zur Einführung der Truppenordnung 61 zugeteilt, sie wurden 1963 durch SE-222 ersetzt und 1967 liquidiert. | ||

+ | ==== Development ==== | ||
+ | Four stations of the wireless station M44 were constrcted in 1943/44, and these were handed over to the troops "for experimental purposes" | ||
+ | |||
+ | ==== Mission ==== | ||
+ | The four stations M44 were assigned to Signal Division 6 as individual stations. When troop order 61 was introduced, they were replaced by [[SE-222]] in 1963 and were liquidated in 1967. | ||
