2-16 RECOGNITION AND IDENTIFICATION OF JAMMING.

Under real or simulated tactical conditions the receiver can be

jammed by the enemy. Enemy jamming is done by transmitting

a strong signal on the same frequency as that used by the

receiver for communication, making it difficult or impossible to

receive the desired signal. Unusual noises or strong interference

heard on the receiver may be enemy jamming, signals from a

friendly station, noise from a local source, or the receiver may be

defective. To determine if the interference is originating in the

receiver, disconnect and remove the antenna leads, or short the

ANT post to the chassis. If the interference continues, the

receiver is defective. Enemy jamming signals may be typed as

continuous wave or modulated. A jamming signal may be

intended to block a single frequency. This is called spot

jamming. The enemy may use one or several transmitters to jam

a block or band of frequencies. This method is called barrage

jamming.

a. Continuous-Wave Jamming. CW jamming is transmitted

as a steady carrier. This signal beats with another
