NOTE: DATE HAS CHANGED to July 29th
Scenario: SCC ARES/RACES has been asked to provide and coordinate responders to assist a local agency in finding some lost radios with stuck transmitters in a city park. Radio Direction Finding (RDF) techniques will be used to locate each transmitter.
FUN Part: A 45 minute introduction to RDF will be given at the park before the search teams are deployed. Participants will self-organize into field teams of two or more people. Teams will need to maintain communications with Net Control. A map will be provided and used to report grid-based locations.
DRILL Part: This event is being conducted as a “mini-drill” and will count for SCC MAC county drill event credit. All SCC MACs/MITs are to follow county procedures for this event, including: Resource Net mobilization and demobilization, all required forms filled out, procedures, equipment, personal dress, etc. in order to receive drill credit).
STAFFING Part: The ICP will include up to four NCO event operators, two NCO resource net operators, and command staff.
RDF Equipment and Preparation: Please bring your own equipment if you have it. If you don’t have any equipment and are interested in direction finding, you are quite welcome to attend. A limited amount RDF equipment will be available for “loan” during this event. Please read up and be familiar with the Radio Direction Finding course material located under the Training and Events section of the county website. Note: anyone can build a cardboard shield tube, see below.
Plan to walk for 1.5 to 3 miles during the course of the 60 to 90 minute assignment on mostly paved park paths, some grass and/or dirt paths. No hills. Dress for the expected weather on the day of the event. Please bring sufficient water and food as for your personal needs. Bring appropriate personal sun protection. Shorts are permitted at this event. No open toe shoes!!!
Bring and wear your identification vest. This is a very public location and you need to be clearly identified as a ham radio operator participating in the drill.
If you have pedestrian 2m RDF equipment, please bring it
Bring a compass if you have one (or equivalent) to practice taking bearing measurements.
MAC Evaluations: A limited number of N3, F3, and S3 evaluation positions will be available. Please indicate your interest when you register.
Tentative Participant Schedule:
0800-0845, participants mobilize, travel, arrive and check-in at staging
0900-1000, incident Briefing, introduction to radio direction finding briefing and demonstration, personal safety and public awareness in a public park briefing, and field team break outs.
1000-1200, field team deployments
1200-1230, participants check out and demobilize
LOCATION: Cuesta Park, Mtn View. Parking lot entrance Montalto & Cuesta.
Cardboard Shield Tube: One of the simplest methods for performing direction finding is the body shield technique. This is aided by the use of a cardboard shield tube. Here is what you need to build one: first, a handheld ham radio receiver or transceiver (e.g., an HT or a scanner) on a lanyard. Go find a cardboard shipping tube that is sized with a large enough inner diameter so you radio fits inside the tube and a long length so your entire receiver + antenna can be fit entirely inside the tube, cut off any unnecessary amount of the cardboard tube. NOTE: the tube does not have to stay perfectly round and you can squeeze the tube if you need to. Go get tin foil and cover the tube and one of the openings with four layers of foil. Completely tape over the foil with duct, gaffers, or similar tape to protect the foil. What you then have is a cylinder of shielding that is open at one end. Holding vertically, you lower your radio into the tube with the lanyard until the signal of interest disappears. We’ll show how to use the tube during the introduction.
Note: Please review the prior classroom course material prior to the exercise.
Additional Information will be available as we get nearer to the event. Please make sure all your contact information is correct in the database.
