    All controls are on the front panel. The PRC1099A consists of the transceiver and battery pack. The PRC1099A is held in its case by four captive screws. A battery box that protects and houses the battery is attached to the case by two clamps. To prevent movement, the battery sits on a foam pad attached to the bottom of the case.

  • Page 11: Single Sideband And Hf Communications

    This section discusses single sideband (SSB) mode and high frequency communications to provide more effective communications. Single Sideband The PRC1099A provides voice communications in SSB mode. This mode provides more efficient operation for high frequency communications than the FM (frequency modulation) mode used for tactical communications in the 30 to 88 MHz range.
  • Page 12 This means that the SSB transmitter puts all of the power into one information carrying sideband. This makes the PRC1099A as effective as a 120W AM transmitter. Apart from the improved efficiency, the SSB signal occupies less than half the frequency space of the AM signal and permits much better utilization of the crowded HF spectrum.
  • Page 13 However, during periods of low sunspot activity, this frequency range will be completely dead. It is important to remember that at the higher frequencies there can be skip zones; and a strong signal may be received from 2000 kilometers away, while closer stations cannot be heard.
