TRADOC Bulletin 15: Battle Report: Squelch Capture

Abstract

This report informs Army operating forces of problems created by Threat interference of communications nets and its effect on command, control, and communication capabilities. It specifically addressed Warsaw Pact VHF jamming capabilities used against the US AN/VRC-12 series radios--the radios used most frequently in US Army tactical units. Included are actions that individuals and units can take to combat VHF jamming and countermeasures now being considered by the Dept of the Army. Squelch capture is the capability of some Threat jammers to prevent friendly communications from being received on VRC-12 series radios. It is one of the most serious threats to US military tactical FM communications. While all enemy jammers pose a threat to communications, some have a more serious effect than others. In the case of VRC-l2 series radios, Threat jammers are able to transmit signals that prevent friendly transmissions from being heard without the victim operator knowing that his radio is being jammed. The effect on the VRC-l2 radio receiver from this type of jamming is called the squelch-capture effect.
