FUG. XXI


A very interesting item now, a FuG.XXI receiver. Well, I say rx, a small point the seller forgot to mention was the heavy mods done to it, still, basis for a restoration project. Great help from our German Agent 'Ted DJ3YR' has revealed more details.

Left: Set as it arrived.

Now the set as it should look along with its matching transmitter.
And the full aircraft installation on the far right.

E-381H


A Real early item, the receiver as used in the Zeppelin airships, E381H. Some restoration needed but an interesting project. The later S version used on U-Boats.

LEFT: Hindenburg radio room

RIGHT: A picture of the hydrophone room of the U-995, a type VII U-boat: The hydrophone or listening room also served as the backup radio room and in this room the spare HF receiver and transmitter were located. The Telefunken E381S backup HF receiver can be seen in the front center of the picture above. The E381S is similar in shape to the earlier E381H ("Zeppelin") receiver which does not have a meter on the front center.

Ha 5k 39b


The Hagenuk 5K Marine set, receiver transmitter (power supply external) used in Naval Installations, harbour control etc. 5 Watt output.
This is a 5 Watt transceiver for the frequency band 2.0 - 5.0 MHz. Modulation is CW or AM.
A3: 1.5 Watt A1: 5 Watt, RX 3x RV12P2000, TX 2x RV12P2000, RL12P10, regulator: GR150A

LO40K39


The LO40K39 HF transmitter, real beast of a set.
lo40k39 fl152

This is a HF transmitter developed by Lorenz around 1936, and was used by Kriegsmarine and Wehrmacht. Lo40K39d consist of transmitter type S. 23725/I and power supply type RGLE. Frequency range is from 3.0 MHz to 16.667 MHz in Range 1: 16.667 MHz to 9.200 MHz, Range 2: 9.300 MHz to 5.000 MHz, Range 3: 5.200 MHz to 3.000 MHz. Oscillator valve is RL12P35 and Output has 2 parallel RL12P35 with Output power of 70 Watt, AM/CW. Weight tx: 35.4 kg, psu: 38.5 kg.
Right: Another version, recently obtained, used by Danish Forces etc after the war, with FL152 tubes instead of RL12P35. The picture is as the set was advertised by the Dutch seller in Hoogeveen but unfortunately, due to the seller thinking the fairies would carry it all the way here on a bed of feathers and so decided not to include any padding in the box, the set arrived damaged, maybe beyond repair but it will certainly take some work to get going now.

TORN eB


The Torn B Emfanger or receiver, TRF, hf coverage, WWII, field troop use, set on top, battery box below.

RIGHT: A set of German WWII Field Phones, bakerlite, very nice styling, a little different to our Type F.

HMZL OKW


A German receiver, the HMZL OKW 34 hf receiver.

okz

Super-Heterodyne (Super in general); IF-Freq. 280 kHz Valves / Tubes 9: EH2. Receiver with BFO, covers ~ 2 - 22 MHz in 6 bands,
HMZL34 OKM [Philips] (see VO34) 4x EH2, 4x EBC3, EL2, Typ1461, 4687, 13202X, IF=280kHz.
Original receiver is VO34, a Dutch aircraft receiver which Germans used under designation HMZL34. Systemized to use only 3 types of valves, but unlike the Germans they chose a heptode instead of a pentode. There are a few differences: BFO valve EH2 was changed to EBC3 (to avoid using an extra signal diode), and some changes in the heater circuit.

HELLSCHREIBER


A recent addition here, a 1940 Hellschreiber, acquired with the very good help of my friend Timo. The unit is in very nice condition and even works, after 62 years ! I hope to have it on the air with a German tx very soon. (click on pics for slightly bigger views)

Made by RFT VEB Funkwerk Köpenick in Berlin around 1975 to 1988. The set was originally designed for both military and civilian use. The notorious Stasi (secret police) has certainly used them. The SEG-15 is a CW-SSB transceiver with a range of 1.6 to 11.999 MHz, both USB and LSB is possible. The output is switchable between 3 or 15 watts.
