  Data-Burst Devices
  6-63. To further reduce the chance that the enemy will use radio direction finding (RDF) equipment
  against them, the BRS and teams use data-burst devices. They can use the nonsecure OA-8990/P digital
  message device group, KL-43F, or portable computer. These devices shorten transmission times--they do
  not prevent the enemy from intercepting the radio traffic.
  PROCEDURES
  6-64. These procedures apply to interference, jamming, and deception. When someone at the BRS or on
  the team hears interference and suspects jamming, he should--
  • Remain calm and continue to operate as if nothing unusual is happening.
  • Prevent the enemy from knowing whether his jamming is successful or detected.
  • Switch to a higher power on the radio.
  • Reorient the antenna to the receiving station.
  • Report the jamming using the meaconing, intrusion, jamming, and interference (MIJI) report
  format in the signal operating instructions supplemental instructions (Table 6-11). Send the
  report over a network free of jamming and interference to ensure that it reaches the intended
  recipient.
  • Until communications can be established and maintain over the desired frequency, use an
  alternate one.
