  The AN/PRC panel can be operated by:

  - Radio Traffic Operators
  - Commanders
  - Officer Adjutants
  - Advisors
  - Platoon Sergeants
  - CLF Cell Leaders

  The handset can be used by anyone within range.

  ## Signal Range

  The following AN/PRC ranges assume [bold]TX MED[/bold] and a whip antenna.

  Transmit power and antenna type modify AN/PRC relay range.

  Faction nets, including squad, command, intelligence, JTAC, and MP, require coverage from at least one of the following:

  - A powered AN/PRC worn by a trained operator.
  - A deployed retransmission station.
  - A command-post antenna mast.
  - A powered communications array.
  - A vehicle radio set aboard a dropship or vehicle (covers little more than the hull).
  - A field antenna mast, raised from ten metal sheets by engineering-trained personnel.

  Colony and civilian channels are not relay-gated and keep stock behavior.

  </Table>

  Replacement fill cards are obtained through the normal supply system.

  ## Direction Finding

  The following traffic creates a direction-finding signature, from highest to lowest risk:

  - PT traffic.
  - Faction-net traffic sent without matching fill.
  - Secured FH traffic.

  Secured SC and CT traffic do not create a direction-finding signature.

  Repeated signature-producing transmissions from the same location increase the chance of detection. Direction-finding risk decreases after approximately one minute without another qualifying transmission.

  [bold]RADIO CHECK[/bold] reports which stations receive the active net clearly or with degradation.

  When used inside a jammer field, it also reports a bearing to the strongest jammer.
