They identify a tent that they think houses the jamming transmitter.

Unfortunately for them, it was that same jamming transmitter that sealed their doom.

Later electronic warfare jamming transmitters were added to the RB-66s, increasing the mission workload.

There were also times when jamming transmitters were (temporarily) off air due to breakdowns or maintenance.

The Soviets (and most of their Eastern bloc allies) used two types of jamming transmitter.

One early Soviet attempt at jamming western broadcasters used the noise from the diesel generator that was powering the jamming transmitter.

Receiver equipment and antennas are mounted in a fin-tip pod while jamming transmitters and exciter equipment are located in under-wing pods.

And Deutsche Welle, the German foreign broadcasting service, has leased and adapted old jamming transmitters from the Soviet Union to boost its signal into Asia.

The connection to Arkon was broken off almost at the same moment a jamming transmitter was put into operation, which prevented even the ships stranded at the spaceport from sending calls for help.

In general outside of the USSR itself Bulgaria was one of the most prolific operators of jamming transmitters in the Eastern bloc with East Germany the least.

With only a finite number of jamming transmitters available at any given time, it may be more efficient to block clandestine stations intended for a large audience rather than a message intended for a single person.

These aircraft were ultimately fitted with APT-16A and ALT-7 jamming transmitters, Airborne Cigar and Carpet jammers, APR-4 and APR-9 "sniffing" receivers, and chaff dispensers.

Early efforts by the U.S. Naval Research Laboratory produced the XCJ jamming transmitter installed aboard the destroyer escorts USS Herbert C. Jones and Frederick C. Davis in late September 1943, too late for Salerno.

These prisoners were chosen to be moved, rather than executed, because Albert Speer, the German armaments minister, felt that the special skills these prisoners had gained at the Phillips factory would be useful in other German factories for the manufacture of "jamming transmitters and equipment for high-performance aircraft".

This system jammed the Strassburg receiver's intermediate frequency of 3 MHz, and appears to have been quite successful, especially as the operator did not have to attempt to find which of the 18 Kehl/Strassburg command frequencies were in use and then manually tune the jamming transmitter to one of those frequencies.
