Radio Communications & Callsigns

Radio etiquette, concise transmissions, unit identifiers, status updates, and reporting stops, pursuits, arrests, and emergencies.

The radio is how NHP stays coordinated. Clear, short, professional transmissions keep the channel open for everyone.

Mandatory
  • ·Department members follow existing NHP callsign procedures.
  • ·Public server members are not expected to have an assigned NHP callsign.
  • ·Use plain English when a radio code is unknown.
  • ·Use only approved radio codes. Do not invent official NHP codes.

Standard radio etiquette

  • ·Think before you transmit. Know what you are going to say before you key up.
  • ·Pause before speaking to make sure the channel is clear.
  • ·Keep transmissions short. Say what you need, then stop.
  • ·Acknowledge calls and assignments promptly.
  • ·No chatter, no jokes, no out-of-character talk on the radio.

Concise transmissions

  • ·Lead with your unit, then the message.
  • ·Give location, then direction, then what you have.
  • ·Use plain language. Do not invent codes the server does not use.
  • ·If a transmission is long, break it into short pieces.
"NHP-4, traffic stop, northbound, county line, blue sedan, plate out."
"NHP-2, status check, code 4, available."

Callsigns

  • ·Department members use their assigned NHP callsign on every transmission.
  • ·Public server members are not expected to have an assigned NHP callsign. Use a plain unit description if no callsign is assigned.
  • ·Report on patrol, on scene, available, and off duty as your status changes.
  • ·Answer status checks immediately. An unanswered trooper triggers a welfare search.

When in doubt, plain English is always correct.

Reporting stops, pursuits, arrests, and emergencies

  • ·Traffic stop = unit, location, vehicle, plate status, and when it clears.
  • ·Pursuit = unit, direction, vehicle, reason, and updates at each junction.
  • ·Arrest = unit, charges, and that you are transporting.
  • ·Emergency = unit, location, what you have, what you need.
"NHP-1, traffic stop, eastbound at the county line, plate out."
"NHP-4, in pursuit westbound, silver sedan, hit-and-run suspect, requesting a supervisor."
"NHP-2, arrest complete, one in custody for reckless driving, transporting to booking."

Requesting backup

  • ·State your unit, your location, what you have, and what you need.
  • ·Be specific: one unit for traffic, a supervisor, EMS, spikes.
  • ·Release units once the scene is stable.
"NHP-3, collision with injuries on the interstate, requesting one unit and EMS."
"NHP-1, requesting a supervisor for a pursuit in progress."

Approved radio codes

  • ·Use only radio codes NSRP has documented and approved for NHP.
  • ·The shared 10-Codes & Radio reference in the sidebar lists the codes the server uses.
  • ·Do not invent codes or claim the server uses a system it has not configured.
  • ·When a code is unknown, plain English is always correct.

The 10-Codes & Radio and Law Enforcement Basics pages in the Reference section of the sidebar hold the server's approved reference material.
