Overview of Today OSH Requirements, tea, coffee & toilets You will not remember everything. Comms GPS More GPS Briefing and Exercise
Communications Will only deal with VHF today Emphasis on developing good habits There will be a lot of radio traffic and a bit of fun during the exercise.
ICOM buttons P0 - Press and hold to lock/unlock P1 – High / Low Power P2 – Change Bank P3 – Talkaround (Repeater Only) Scroll up and down through channels
VHF Handsets Two different radios, but effectively the same. Check batteries, plus spare set. Microphone and Floppy Jim aerial Turn on and adjust volume using tone Check correct channel Radio Check Set volume to “Just Enough” Turn radio down when doing sound lines
Radio Procedure Write down message time and time sent If you're not prepared to write it, don't say it. Check channel clear Press the transmit button, wait 1sec, then call “SAR Base, SAR Base, from Team 2” Release to listen Once Base (or other station) acknowledges, proceed to transmit message.
Radio Procedure Speak slowly – someone has to write it down Transmit 1 sentence at a time Long messages should be broken with “More to follow”....Does it need to be this long? Read back grid references to confirm Write down messages received Do not transmit sensitive information Remember who may be listening...
Radio Procedure In case of fatality, severe trauma or near death “I have a message for the Incident Controller” Then transmit only information requested – usually go onto cellphone, but not always. If it goes to the Coroner – your radio logs may be requested. If it isn't written down, it didn't happen.
Radio Relay Used if team can be heard trying to contact base but not getting through – or vice versa. Offer to act as relay to station calling Establish contact with second station, advise. Avoid Chinese Whispers – write it down. Call “Team 3, Team 3, relay from SAR Base” Once completed, advise both stations that relay has ended
On Arrival Back at Base Turn radio down (preferably off) If standing down, hand to TL for signing in. Advise of any faults, damage
Emergencies Urgent Message: “This is a Priority Message” Over-rides general messages Incident during SAREX / Exercise: “This is a Genuine Message” or “No Duff” Signifies event has occurred that is not part of training scenario Immediate Threat to Life: “Mayday, Mayday, Mayday. This is…. “ If you hear any of these transmitted, all other communications must cease until Base advises channels are clear for use again.
Questions and Discussion
NAVSTAR NAVigation Satellite Timing And Ranging We civilians call it “The GPS System” Started in 1978 Full Satellite network in place by 1994 Life of satellite 10 years Signal only 50watts
NEW PROCEDURE In order to avoid the “Spiders Web” A new tracklog procedure has been proposed: Tracklogs are left ON On arrival at tasking, CLEAR tracklog. At completion of tasking, SAVE tracklog. At start of new Tasking, Clear tracklog …and so on. This separates each task clearly The Tracklog page is now one of the Main pages
DON’T WORRY ! You will have GPS cheat-sheets to take with you on the Exercise! Couldn’t ask you to remember all this…
Golden Rules of GPS Never trust it with your life Carry a map and compass (except today) Recommended to have a spare set of batteries Practice, practice, practice!
Minute Mayhem ! When you hear an All Teams Broadcast of “Minute Mayhem” Change GPS to Decimal Lat / Long (eg: 34° ') Your goal is then to waypoint as many locations as you can until the stop signal
RULES OF ENGAGEMENT The last 3 digits correspond to a time E.g. 174° would be 2:45pm and so on. Either Latitude OR Longitude marks are acceptable Bonus points for both (eg 35° ' 175° at 3:34pm) GPS clock is the reference for time Marks must be named using MM1, MM2, MM3 to be valid Tips: Plan your strategy beforehand Each minute in time equates to ±2m distance on the ground
