When jamming is first detected, try the following checks to reduce the effects: Anti-Jamming Action Position the PRC1077 to make use of nearby obstructions to act as a screen against the jamming source. Experiment with different locations as the interference signal strength may vary substantially over very short distances. -
Page 43: Voice Security
3: Operation The PRC28 operates from 30 MHz to 42 MHz, leaving the PRC1077 with an unusable frequency range from 43 MHz to 87.975 MHz when communicating with the PRC28 transmitter. These unusable frequencies can provide security and protection from jamming if an enemy is using a PRC77 or PRC28 transmitter. -
Page 45: Chapter 4: Maintenance
• Perform the Operational Checklist. The following is a recommended procedure for weekly preventative maintenance to keep the PRC1077 and accessories in good working condition. • Inspect the handset cable for fraying, cuts, kinks and broken insulation. • Inspect all cloth items for fraying and tears. - Page 46 Make the following operational checks before and after using the PRC1077.

20 or 30 miles are easily achievable. Unfortunately, locating transceivers on elevated sites is not always possible. A relay system uses two PRC1077 positioned on elevated sites to relay signals. The two transceivers are connected using the MK-456/GRC Retransmission Cable Kit. -
Page 50: Repeater Operation
(refer to the Frequency Interference Chart on page A-4). The PRC1077 transmitter is compatible with the PRC77, so both types of transmitters can be used to create a radio relay system. Dedicated Receiver A dedicated repeater is a receiver/transmitter combination specifically designed to be used in a repeater system. -

These factors help ensure the best service area coverage. PRC1077 Repeater Installation When using the PRC1077 in a repeater system, use the 1077 Retransmission Repeater Cable Kit to connect the two radio sets. The 1077RETRAN includes a 50-foot cable with connectors to connect two PRC1077 transceivers together. -
