DO Radio Communication Guide

Good radio comms are critical for convoy safety. Here's the DO standard guide: **Call Signs:** Use your DO handle/nickname as your call sign. Keep it short and recognizable. **Standard Calls:** - 'All stations, all stations' — announcement to entire convoy - 'Marshal, this is [name], I am stuck at [description]' — stuck vehicle - 'Copy/Roger' — message understood - 'Negative' — No / not understood - 'Stand by' — wait for further info **Radio Discipline:** - Keep transmissions brief - Always identify yourself - Don't hold the channel unnecessarily - In emergencies, repeat 'MAYDAY' three times **Channel Protocol:** Lead marshal controls Channel 1. Do not break in unless urgent. Use Channel 2 for inter-vehicle chat during stops. --- ### Clear and Disciplined Radio Communication in Desert Formations Following a disciplined **radio communication guide** is the central nervous system of any organized desert convoy. Over sand dunes, direct visual line-of-sight between the Lead Marshal, intermediate vehicles, and the Sweep Marshal is repeatedly broken by crests, valleys, and blowing sand. Without dependable voice protocol, minor delays can quickly escalate into hazardous situations. #### Essential Rules of Radio Etiquette 1. **Listen Before Transmitting:** Always pause for two seconds to verify nobody else is currently speaking on the frequency before pressing the Push-To-Talk (PTT) button. Stepping on someone else's transmission garbles both messages. 2. **Think, Key, Speak:** Formulate your message clearly in your mind before keying the microphone. Key the PTT, wait half a second for the repeater or radio tone to initiate, speak clearly across the microphone (not directly into it), and release the button immediately. 3. **Relay Protocol When Out of Range:** If a stuck driver in a deep bowl cannot reach the Lead Marshal at the front of the convoy, an intermediate vehicle stationed on an elevated dune ridge must serve as a communication relay: *"Lead, this is Vehicle 4 relaying for Vehicle 8: Vehicle 8 is cross-axled in the bowl behind crest 12; Sweep is currently assisting."* #### Handling Critical Emergencies In the event of medical distress, roll-over, or severe fuel leak, declare: *"MAYDAY, MAYDAY, MAYDAY. All stations, stop vehicles and maintain absolute radio silence."* At that command, every driver must halt immediately in a safe position and keep channels clear for the Marshals to execute emergency response procedures.
