German Historic Items

In the pre 1977 period (Before The German and other European governments gave in and allowed CB, there were CB sets made for industrial users, Transport companies, local Fire Services, large Farms, medical professionals, etc., where these needed mobile communications. Kaiser in Germany was then making customised CB sets for these users as in the example below made in Nürnberg by Kaiser GmbH / German Weston. On the right side is the PSU part and includes a tone-call discriminator for radio telephone use. The users needed no special skills but an expensive licence was needed from the German Post Office.

SEM 35 (German Army Man-pack for backpack and/or Vehicular Mobile use)
26,00-69,95MHz in 880 channels with 50 kHz spacing

Here the SEM-35 is shown fitted onto the Vehicle mounting plate, right a spare battery box for Manpack use is shown. On the Left the AGAT (Automatic ATU) can be seen. To the front there is a ribbon (Blade) antenna, and a typical German (US) Army handset. I incorrectly show the use of both the base plate aerial connection (Cable no. 23 bootstrap) and a Rod Antenna on it’s bendy spring going off the top of the picture. When the blade or rod antennae are used it disconnects the BNC connector on the front panel that goes normally to the Vehicle mount and then to the AGAT.

On the right the AGAT (Automatic ATU) side on and also looking top on opened to see the C and L adjustment wheel that is driven round by motors to select the correct match.

My Former Radios / Meine Vorherigen Geräte

Radios I once had and have since lost (over time) through Sale, Divorce or otherwise...

British Army WW2 Reception Set R107 Mk 1.

I had one of these R107s in the 1960s, (in fact two, one to restore, and one that had been shot through with a machine gun and served as parts for the other one) The R107 was a self contained Rx with a built-in 12V DC and 110/230 V AC Power Supply. A panel on the front allowed a quick test of many different supply rail voltages and test points without needing to open the set. Reception Set R107 Mk 1 was a general purpose HF receiver. With a Frequency coverage from 1.2 MHz to 17.5 MHz. AM R/T and CW and with the BFO and narrow bandwidth filters also good for SSB signals.

Based on a No- 8 set a portable man pack for short range communication, comprising of separate transmitter/receiver in a common case with battery compartment in the bottom. It was developed in 1940, and used in forward areas between Battalion HQ and Company HQ.

The frequency range was 6 to 9 MHz. MO control. Despite having a RF output of only 0.25 Watts in R/T or CW mode, it was capable of ranges up to 10 miles. In 1942 the WS No. 18 was “re-developed” by the USA as the No. 48 set.

Later (in 1943) the No. 68 Set (which is similar but with different frequency range of 3.0 to 5.2 MHz and 1.75 to 2.9 MHz as WS 68”P” model) came out. It also had a Xtal control option.

I also had several other WW2 sets in the 1960s including a 19 Set, a 22 Set, a 62 Set and an RAF 1115 Lancaster Bomber receiver.
