Abstract:

The results of two field tests of radio transmitter set ANMRT-4XL-1 are set forth. The first test determined the interference which the jammer causes to a division-area grid communications system employing Radio Terminal Set ANTRC-24 the second test determined the jammer interference to a VHF circuit employing the airborne radio set ARC Type 12. It was found that the jammer must be separated from any terminal of a grid equipped with the ANTRC-24 by a distance of 1 mile to avoid disruption teletype communications. The ARC Type 12 receives significant interference within 12 mile of an ANMRT-4XL-1, but beyond that distance can operate through minor interference. Also see AD-311 203. Author
