The Kurz - Lang - Bodenstation 1001 eF (Short - long ground station) developed in 1938 by Telefunken Berlin had been constructed as an aircraft station for intercontinental communications for large aircraft; the station in two steel tube racks would fit perfectly into a small truck to be used as a motorised ground station.

Wireless ground station with separate transmitter and receiver,

Transmitter: Telefunken As 1017: 300 - 600 kHz und 3,75 - 12 MHz
Receiver: Telefunken Ae 3013, 300 - 620 kHz und 3 - 12 MHz

Telegraphy CW (A1), telephony (A3)

pout Shortwaves: A1 45 W / AM 13 W
Longwaves A1 70 W / AM 20 Watt

Sensitivity: A1 2-3 uV, A3 5-6 uV


Transmitter: powered by 27V = from vehicle generator 30 A or two-stroke engine powered compound generator BBC 27,5 V / 29 A,
Receiver: 26,5 V = / 2,6 A or mains 110 - 250 V.

The Kurz - Lang- Bodenstation 1001 eF (Short- Longwave ground station 1000 eF) has been developed by Telefunken Berlin GmbH in 1938 and has been built by Telefunken / Albiswerke Zürich AG, the 25 stations (Ritter has 35 stations) were constructed in 1939/40.
The equipment was primarily constructed as an aircraft station, by this fact the strange power requirement of 27V DC is explained. The compact dimensions made the station suitable to be installed in steel tube frames on board of a light truck, so it could be used as motorised aeronautical ground station.
Due to the war in Germany, Telefunken could not deliver the parts to assemble further stations at the Telefunken Zurich / Albiswerke plant. So Zellweger, Uster, got a contract to construct further station with similar dimensions based on existing Zellweger sets - the KL43 / G-Station was the result of this.

The receiver is the Telefunken Ae 3013, a superhet with one RF stage and two AF stages, in the receiver with the IF of 1312 kHz, seven valves NF4 are used. sieben Stück NF 4 Röhren bestückt. The receiver covers longwaves 300 - 620 kHz and shortwaves 3 - 12 MHz in three ranges.
This receiver was the weak point of the station, with his reedback IF stage, theselectivity of the set was considered as not sufficient for this kind of ground station
The receiver can be powered from the aircraft on-board power system with 26,5 V or from mains.

The double stage transmitter Telefunken As 1017 has variometer tuning in two longwabe ranges from 300 - 600 kHz and in four shortwave ranges from 3,75 - 12 MHz. Four operation frequencies can be mechanically preselected.
The transmitter has grid modulation, three valves NF4 are used in the low signal stages and three valves RS 287 in the driver and RF output stage. The transmitter has a VOX, a voice operated transmit - receive switch when in telephony mode.

The station is powered from 27 Volts DC from vehicle generator when operated on board a truck and from a two-stroke fuel operated generator DKW when the station is operated stand-alone, the plate voltage is generated by a vibrator.

The receiver frame has a weight of 55,4 kg and the transmitter frame a weight of 71 kg, the complete station when operated stand-alone has a weight of 704 kg and the Truck Berna CR1D with the complete station 3800 kg.

When used onboard the truck, the 12 m vehicle antenna is used, if time and space allows, a 12 m mast made from pluggable elements is used for shortwaves and for longwaves a 29 m long wire antenna between tro 12 m masts.

The long- / shortwave station "Die Kurz - Lang - Station" has been used in the Anti Aircraft Coordination Network of the Anti Aircraft Troops (which made a part of the Air Force) by the signallers of the Anti Aircraft Communications Company (Flab Uem Kp). After the reduction of the wireless communications activities of the Air Force, the station has been handed over to the Signal Companies of army divisions for command traffic after 1951, in 1961, the station has been withdrawn from service and has been liquidated.
