PART G - OPERATOR'S DUTIES WHEN JAMMED
Before concluding the discussion of communications jamming, radio operators should
note three points.
Transmit a stronger signal toward a vulnerable receiver than normally would be
Continue radio operation even if jamming is successful.
Report jamming promptly, accurately, and completely to the communications
1-41. By careful engineering of communications systems, jamming can be minimized, or even
eliminated. An effective means of minimizing jamming is to transmit a stronger signal than
normal toward a vulnerable receiver. This can be done if the transmitter is capable of producing
different levels of output power. The extra power produces a high signal-to-jamming ratio at the
Thus, to effectively minimize jamming, transmit a ____________________
(stronger/weaker) signal than normal toward a ____________________ receiver.
(1-41. Answer: stronger, vulnerable)
1-42. If hostile jamming is taking place, the one basic rule that an operator should follow is to
continue radio operation regardless of the noise level and the availability of alternate means of
communications, unless otherwise ordered. A shutdown station tells the enemy jammer that his
efforts have been successful. The enemy can never be certain that his jamming is successful if
radio operation is ________________.
(1-42. Answer: shutdown)
1-43. If individual stations have shut down during jamming, the enemy shifts to another station.
By continued operation, enemy jamming equipment is effectively tied down by persisting in
jamming the station. Therefore, the best way to protect other stations from ECM attack is to
