 +====== SE-215: Heavy Portable Wireless Station 40 ======
 +**Tragbar Schwere Funkstation 40** (Heavy portable wireless station), **TS 40**; developed and produced by [[Zellweger AG, Uster]].
  
 +As a replacement of the [[SE-214|Tragbar Schwere Funkstation 18/25]] (Heavy portable wireless station 18/25) and the "Fahrbar Leichte Funkenstation 19/25" (Light mobile wireless station 19/25), [[Zellweger AG, Uster]] developed a new wireless station covering the longwave and shortwave band in the years 1938 - 1940.
 +
 +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, in case 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 **Tragbar Schwere Funkstation 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.

 +
 +===== Technische Daten =====
 +  * [[Principle]]: Wireless station with separate transmitter and receiver
 +    * [[Receiver]]: [[E-601|E41]]: [[Double conversion|Single /double conversion]], [[IF]] 70 / 465 kHz
 +    * [[Transmitter]] [[S-300]]
 +  * [[Modes]]: [[A1]] with BFO, [[A3|AM (A3)]], [[A3J|SSB (A3J)]] reception with BFO
 +  * [[Frequency range]]: 190 - 715 kHz, 1,5 - 4,5 MHz (Transmitter)
 +  * [[Sensitivity]]: [[A3|AM (A3)]]  / [[Selectivity]]: 
 +  * [[Output power]]: [[A1]] 100 W, [[A3]] 25 W
 +
 +==== Power Supply ====
 +  * Petrol operated or elektric 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 which was 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.
 +
 +==== Dimensions ====
 +  *  The weight of the complete station equipment is 545,5 kg.
 +
 +==== Accessories ====
 +  * Longwave antenna: Long wire antenna 50 m between two 10 m masts
 +  * Shortwave antenna: 10 m mast antenna or 8 m long wire antenna between two 10 m masts.
 +
 +===== Station components =====
 +Al components of the **Tragbar Schwere Funkstation 40** are exchangeable and electrically identically to the components of the **Fahrbar Leichte Funkstation 40** ([[SE-300|FL40]]). The complete station equipment with a total weight of 545,5 kg could be carried by 23 persons (if the cable chest, a lamps set and the electric motor were omitted, 20 men were enough) or it could be mounted on six mules to be transported in mountain regions.
 +
 +If mobile use was not necessary, e.g. for the installation in command posts or a fortress, the equipment could be transported on a truck - so transportation by men was a rare occasion, usually only in instruction service.
 +
 +===== Technical principle =====
 +The main receiver [[E-601|E41]] is a [[Double conversion|Single- / double conversion]] set with an [[IF]] of 70 / 465 kHz. 
 +
 +The transmitter [[S-300]] is virtually identical to the one used in the "Fahrbar Leichte Funkstation" [[SE-300|SE-300 (FL)]] and has three longwave- and three shortwave frequency ranges.
 +
 +==== Valve Layout ====
 +refer to the pages of the components
 +
 +==== Development ====
 +As a replacement for the [[SE-214|Tragbar Schweren Funkstation 25]], [[Zellweger]] developed a portable variant (with the components in individual chests) of the [[SE-300|Fahrbar Leichte Funkstation 40]]. It's components could be transported on a truck or could by carried to their position on the backs of men or mules.
 +
 +==== Field Use ====
 +{{ :images:se-215-ts40-im-feld.jpg?direct&400|SE-215 / TS 40 im Feldeinsatz}} Most of the stations have been attributed to mountain divisions; some stations were installed in fortresses.
 +
 +A few other station were installed on the trucks of the military police batallions for mobile use.
 +
 +In the years 1939/45, a total of 45 units of the TS 40 was acquired, they have been in use until 1969. After the introductzion of the single sideband station [[SE-222]], the equipment underwent liquidation in 1971.
