We are fortunate enough to have access to some rare and complete items of radio equipment. Not all are used at the same time - we pick and choose what is most correct for the scenario we represent. For a larger set up, we will use the heavier vehicle mounted sets and for smaller displays, the backpack sets.
Tornisterfunkgerät d2 receiver
This transceiver is a backpack radio set consisting of 2 boxes - the radio itself and the battery/accessory box. The operator carried the battery box, with an assistant carrying the battery box. They were connected together by means of a 2,5 metre cable. Each box weighs around 20 kilograms. The radio has provision for a microphone, a morse code key and 2 sets of headphones. When used in the field, it requires a 2 metre antenna, which breaks down into 6 sections (these are stored in the lid of the battery box). Despite its size, the range of this set is very limited - approximately 9 miles. It requires 2 sets of batteries - a 2 volt storage battery for sending and a 130 volt HT battery for receiving. It operates in the frequency range of 33.8 to 38 MHz.
Feldfunkgerät f transceiver
This is another transceiver backpack radio set, but of a more compact design. The case is made of moulded resin and it is designed to be attached to the Y straps. The set weighs around 13 kilograms and has provision for 2 sets of headphones and a microphone. It has a small remote control device which can be removed from the set and attached to the belt (though this is connected to the set by a wire). This allows the operator to adjust the volume and tuning of the set without needing to gain access to the dials etc on the main panel. The antenna is a 1 metre fixed rod. Again this set has a very limited operational range - only around 2 miles, and the operator must have a clean unobstructed line between his set and the receiving radio. It requires a single type 2.4 battery and operates in the range of 27.2 to 33.3 MHz.
Tornister Funk 'c' transceiver
This is a back pack set which, like the Fu d2 above, has 2 boxes - the radio and the accessories. The boxes each weigh around 22kg, however unlike the Fu d2 it cannot be used on the move as the set has to be rotated through 90 degrees to be carried! Power is the same as the Fu d2 set - one 2B38 wet battery and two 90V dry cells. The set has a range of around 10-12 miles and can either be used with a 3 metre rod antenna or a 25 metre horizontal wire wit counterpoise. The receiving section is on the left and operates in the range of 3 - 6.67 MHz whilst the sender section is on the right and operates in the range of 3 - 5 MHz.
Tornister Empfänger 'b' receiver
This is a back pack receiver set which comprises 2 boxes - one for the set and one for the batteries and accessories. These boxes lock together so they can be carried. The combined weight is around 16 kilograms. The radio has provision for only 2 sets of headphones. In the field it uses a 2 metre trailing wire antenna, though the longer this is, the better reception. The range is dependant on the power of the transmitting unit, and the length of the antenna (with the right antenna, it was possible for troops stationed in France and Russia to listen to German home service broadcasts). As with the d2 set above, it has 2 sets of batteries; a 2 volt wet storage battery and a 90 volt HT battery. It operates in the frequency range of 0.10 - 7.095 MHz.
Vehicle mounted equipment
Fu 11 SE 100
This combination is made up of separate units - the 100WS and either the KwEa or the Torn Eb receiver. The 100WS/KwEa was first used in 1936, and was replaced by the 100WS/Torn Eb in 1941, however the earlier combination remained in use throughout the war (the picture above, from an original manual, shows the earlier pairing in a Kfz 61 vehicle). We are capable of using either.
100W S transmitter
This set is designed to be mounted in a vehicle as it is a bulky set which weighs around 40kg. It's maximum range was up to 250 miles in optimum conditions, which made it ideal for communicating between higher commands (such as between division and regiments). It could be paired with either the Torn Eb above (as the Fu11 SE100 configuration) or with a KwEa receiver (below). Power was provided from either a storage battery connected to a U-100 dynamotor, or directly from a C100 generator set. It was normally used with an 8 metre telescopic mast antenna. It operates in the frequency range of 0.2 to 1.2 MHz.
Kurzwellen Empfänger 'a' receiver
This is a short wave receiver. As with the 100WS, it is designed to be used in vehicles due to its size and weight (48kg). Power is provided either from two 2B38 wet batteries and two 90V dry cells or a specific dynamotor, NA6. It operates in the frequency range of 0.98 - 10.2 MHz
Wehrmacht-Rundfunkempfanger 1/P receiver
This is essentially a radio receiver unit operating on 3 low frequencies (0.150 - 0.425 MHz; 0.517 - 1.54 MHz and 5.9 - 15.5 MHz). It also had provision for telephone equipment and other radio sets to be plugged into it so as to act as a loud speaker. A microphone could also be inserted thus allowing it to be used as a crude PA system.
Lautsprechergerät (Funk) b
This is a simple speaker contained inside a metal box - these were usually issued with signal equipment which was either in a fixed emplacement or was vehicle mounted.
This is a mains power regulator unit which takes an input of between 90 and 220 volts AC (either from a generator or mains supply grid) and converts it to a regulated 12 volts DC suitable for running radios. This is used to power the Torn Eb.
Kurbelmast '9', Ausführung A
This is the telescopic mast antenna '9m', version A. It is an 9 metre tall antenna which can either be used mounted on a vehicle (as above, though not fully extended) or free standing. It extends by means of a crank at the bottom which operates a series of wires - it can be fully extended in about 20 seconds with minimal effort. Our antenna is currently undergoing restoration, but is fully operational.
The picture above shows the asset plate on the base of the mast. It's labelled 'Km 9 Ausf A' (kurbelmast 9[m], Ausführung A - telescopic mast, 9 metre, version A. The picture below shows the spirit level used for levelling the mast during free standing set up.
Finally, the mast almost fully retracted (it's still 185cm tall).
