Selected Foreign Sets

This section documents certain non-U.S. equipment.

U.S.S.R. (KGB) BR-3U Transmitter and "Svir" Receiver

This radio equipment was part of a KGB "leave behind" program in Europe in 1966. It was buried in Switzerland, near Friburg, and 'booby-trapped' with explosives. Similar caches have been found in Italy, Belgium, and perhaps other countries.

In a 1966 article appearing in the CIA-internal journal "Studies in Intelligence", this radio set is described as follows:

"[this set] reflects the application of advanced technology to agent radios. It unquestionably represents a superior system of covert long-distance communications. It has a magnetic tape keyer for automatic transmission at a rate of either 450 or 750 words per minute [using frequency-shift keying]. With an output power of 80 watts and a frequency spread of 4.5 to 18 MC [4-20 MC for the receiver], it is eminently suitable for intercontinental traffic. Such a radio set reveals an extensive commitment of effort to clandestine operations and a high order of professionalism."

The article also mentions that the transmitter case measures about 4" X 9.5" X 13", and the total weight of the set is 33 pounds.

British Mark 119 Radio Set

This set is included here because it's overall size and specifications are very similar to the U.S. RS-1 / GRC-109 set.

German SP-20 Transmitter

This modern German transmitter operates from 2-24 MC, with an output of 15 watts. The power supply accepts various AC or DC voltages (self-regulating), and has an internal battery.

An older version is the SP-15, which operates from crystal-control only.

Info from Louis Meulstee (PA0PCR):

This was manufactured by Pfitzner Teletron in W. Germany [the main contractor for the entire set] apparently in the late 70s-early 1980s (I am still tracing this) [transmitter S-6800 and antenna tuner ASG-6800 were made by Telefunken]. The indication on the harness box says KS30 (Kurzwellen Synthesizer 30) and KE30 (Kurzwellen Empfanger 30?) as type numbers [the KE30 is the matching receiver, but it is reported to not be in production - ed.]. There is also a connection for an external device KUG. The TX may be used without the synthesizer and has a crystal holder.

Miscellaneous

This is a pair of Dutch resistance crystal radios, built into a small metal can, and a matchbox. The image is from a postcard bought at a Dutch Resistance Museum in Amsterdam. The matchbox is marked in Swedish, but Swedish matches were sold in Holland for many years. Image courtesy of Bill Howard.
