==>CALIFORNIA EMERGENCY OFFICIALS SEE ADVANTAGES OF SSTV IN DRILL
by Marvin Johnston 06 May '05

06 May '05

Congratulations to ARES for the part they played in this exercise! *************** The ARRL Letter Vol. 24, No. 18 May 6, 2005 *************** ==>CALIFORNIA EMERGENCY OFFICIALS SEE ADVANTAGES OF SSTV IN DRILL Amateur Radio Emergency Service (ARES) volunteers in California made slow-scan TV part of the communication mix when they participated in a voluntary wildfire evacuation drill April 30. The exercise involved residents of nearly 400 homes in a high fire hazard area of Santa Barbara County, and ARES' use of SSTV definitely caught the eye of emergency officials. "ARES provided us with the only continuous, real-time information on traffic flow and conditions in the incident area," said Jay McAmis of the county's Office of Emergency Services. "It was great!" Santa Barbara South County ARES Emergency Coordinator Lou Dartanner, N6ZKJ, says communicators with SSTV gear deployed at three locations along a narrow, winding road out of the canyon and in two locations along the evacuation route to a reception center some five miles away. Three additional ARES members provided voice reports on traffic flow, while four other team volunteers supported the field activity at the command post and reception center. Since the county's inaugural test of its new "reverse 911" system failed to reach everyone, many residents were alerted instead by sheriff's units using public address systems and by search-and-rescue team members going door to door. "As a result, instead of the traffic jam with fender-benders and finger-wagging, an orderly trickle of vehicles moved out of the area," Dartanner reports. "An SSTV station was set up at the reception center, and a crowd of about three dozen jostled around the monitor all morning, watching the near-continuous stream of pictures coming in from the field. A second, portable system was set up in back of a car at the Command Post, and the Incident Commander was able to see exactly what was--or was not--occurring in the incident area." More than 200 residents participated, as did personnel from 21 agencies and organizations. "Local fire officials are excited about using SSTV capability in the future," Dartanner says, "and ARES will continue to play an important role in their activities."

Two on-foot hunts coming, May 15 and 21
by Marvin Johnston 29 Apr '05

29 Apr '05

You have two opportunities to enjoy on-foot transmitter hunting (foxtailing, radio-orienteering, ARDF) in May. The fourth in a series of local hunts leading up to the USA ARDF Championships this summer will take place Sunday, May 15 in O'Neill Regional Park. This ARDF event is a "mix-in" with a regular orienteering meet of the Los Angeles Orienteering Club (LAOC). The O'Neill two-meter course will be "advanced" level, about the same length as typical national championship courses, with five transmitters. Although it is intended as training for experienced radio-orienteers, it can be completed by beginners who are capable of walking or running in hilly rural terrain for about 5 kilometers. Course-setter Marvin Johnston KE6HTS will be on hand to teach the basic techniques of on-foot direction-finding. One or two ARDF sets may be available for loan. You may start on May 15 at any time between 10 AM and noon, but we suggest that you arrive at 9:30 so you can get registered early and have time for an orienteering course in addition to ARDF. LAOC's participation fee is $5 per individual adult and $3 per individual youth who are LAOC members. Non-member individuals pay $7. Groups of two to four persons can go out on the courses together, in which case the group fee is $7 for LAOC members and $9 for non-members. LAOC's excellent orienteering maps of the park will be provided for your use. Electronic scoring will be used. If you have an "e-stick," be sure to bring it, and if not, you can rent one O'Neill Regional Park is between Trabuco Canyon and the Foothill Transportation Corridor. From Interstate 5, exit at El Toro Road and head northeast toward the hills for 7.3 miles. Turn right onto Live Oak Canyon Road (at Cook's Corner) and proceed 3.3 miles to the park entrance on the right. From north Orange County, go east on Chapman Avenue in Orange to the intersection of Jamboree Road. Go straight onto Santiago Canyon Road 12.3 miles to Cook's Corner, where you will turn left onto Live Oak Canyon road and proceed 3.3 miles to the park entrance on the right. Use the map at bottom of this page for navigation to the park. Vehicular entrance and parking costs $5 per vehicle. Starting area will be near the park entrance. Follow the LAOC signs and look for the orange and white orienteering flag. Then on Saturday, May 21, come to Tri-City Park in Placentia for a pig-out and beginner transmitter hunt. It is sponsored by the Fullerton Radio Club and is part of the club's annual "Antennas In The Park" event, held in conjunction with Western Amateur Radio Association and Anaheim Amateur Radio Association. An optional barbecue and potluck precedes the hunt. To join in, bring your own meat to cook and a side dish or dessert to share. Transmitter hunts will follow the potluck at about 12:30 PM. You may start the course at any time before 1:30 PM. The Tri-City transmitter hunt will be simple, informal and intended primarily for beginners. In addition to two meters, there will be an optional transmitter on the 80-meter band. All ages are welcome, so bring the family. Experienced ARDFers will be present to help you get started. There will not be any charge for participation in the Tri-City hunt. Huntmaster will be Joe Moell K0OV. RDF equipment will be available for loan. Tri-City Park entrance is at the corner of North Kraemer Boulevard and East Golden Avenue in Placentia. The barbecue and hunt start will be in reserved picnic shelters at the south end of the lake. Look for the orange and white Orienteering flags and signs. Entry and parking are free, but empty spaces near the picnic site may be difficult to find if the park is crowded, so consider carpooling. Call K0OV on K6QEH/R, 146.97(-) PL 136.5 for two-meter talk-in. Maps to these sites are at www.homingin.com 73, Joe Moell K0OV

Saturday at the Clubhouse
by Marvin Johnston 21 Apr '05

21 Apr '05

Hi everyone, On Saturday, April 23, come on down to the club station and we can build a DF antenna setup. You can either bring your own parts or I will have them available as kits. The parts cost for the tape measure beam is about $10.00 and the cost for the offset attenuator is about $5.00 - $15.00 depending on your junk box. If you want to build them from scratch, plans for the tape measure beam are on Joe Leggios web site at http://home.att.net/~jleggio/projects/rdf/rdf.htm. The plans for Joe Moells offset attenuator is available on his web site at: http://members.aol.com/joek0ov/offatten.html. I might add that I have permission from both Joe Leggio and Joe Moell to sell kits of their designs. Let me know if you want me to provide a kit, otherwise just show up with the parts and lets do it!!! Afterwards, Ill put on a small transmitter hunt at the Red Cross parking lot to test out the setups. Something else where we need some help is rebuilding and testing out seven antenna rotors so they can be sold (with the proceeds going to SBARC.) Basically, the electrical terminals need to be replaced, and while they are apart, we might as well go ahead and lube them. The club station opens on Saturday about 9:00 AM and closes at noon. See you there!

[ardf-socal] Griffith Park results and upcoming hunts
by Marvin Johnston 12 Apr '05

12 Apr '05

Except for some stiff breezes, it was a perfect day for radio-orienteering at Griffith Park on April 9. Marvin's course through the hills was a real challenge and great practice for the upcoming USA Championships in Albuquerque. (Register now for those championships, because the fees go up at the end of April.) Newcomers included musician Raul Mendez KG6YFS and ARRL Southwestern Division Director Dick Norton N6AA. Raul used his new pole-mounted log-periodic antenna and a borrowed attenuator to find all the beginner transmitters. Dick borrowed my Aussie Sniffer4 ARDF receiver and tape measure beam, grabbed his binoculars and set out for an afternoon of birdwatching. While doing that, he found all of the advanced-course foxes! Jay Hennigan WB6RDV tested out his new FRWD Sport Performance Recorder on the advanced course. Afterward, he downloaded to his laptop and retraced his route, finding his maximum heart rate (170), distance traveled (10 km) and calories burned (1260). ADVANCED HUNT RESULTS Name and callsign Foxes Time Bob Cooley KF6VSE 5 1:01:45 Jay Thompson W6JAY 5 1:10:20 Jay Hennigan WB6RDV 5 1:48:35 Dick Norton N6AA 5 2:33:25 Scott Moore KF6IKO 4 2:20:59 Bill Smathers KG6HXX 4 3:01:07 Scot Barth KA6UDZ 3 2:25:14 Richard Thompson WA6NOL 1 1:41:53 Danny White W6DDW & family 1 1:47:04 BEGINNER HUNT RESULTS Raul Mendez KG6YFS 5 2:30:47 Art Tanaka WA6TKO and Nick 2 1:41:53 The 80-meter transmitter was 1.6 km away by straight-line and considerably more by trail through the hills. The signal was very weak, but four hunters were able to track it down, as follows: Jay Hennigan WB6RDV 0:27:28 Scott Moore KF6IKO 0:57:40 Bill Smathers KG6HXX 1:10:11 Bob Cooley KF6VSE 1:25:20 Afterwards, a bigger-than-average group headed to the nearest Sizzler for much-needed carbs and protein. Everyone is welcome at these post-hunt sessions, so be sure to inquire at the site if you're interested. Just be prepared to wait a while until all the foxboxes are recovered. Thanks again to Marvin Johnston KE6HTS for a challenging course and to April Moell WA6OPS for bandaging up some minor wounds and providing a cold pack to a well-heated runner. Fifteen photos are at www.homingin.com Next month, we'll split up the beginner and advanced hunts. The IARU-style full-length course will be at O'Neill Regional Park in southern Orange County (last hunt there 3/20/04). This time, the ARDF event will be a mix-in with the Los Angeles Orienteering Club meet in the park on Sunday, May 15. KE6HTS will set the course. For beginners, I will put on a special hunt at the annual Antennas-in-the-Park hamfest and pig-out on Saturday, May 21. The festivities take place in Tri-City Park in Placentia, a 60-acre venue that is flat and has a big lake in the middle. It's prefect for newcomers, so if you and your kids/grandkids have never tried on-foot foxhunting before, this is the time. See you next month. 73, Joe Moell K0OV

SSTV Repeater is on the air!
by Rod Fritz 04 Apr '05

04 Apr '05

The WB9KMO SSTV Repeater is back on the air! It's located near Patterson Avenue and the freeway (on my home tower) for now. It ought to serve the Santa Barbara/Goleta area pretty well. Soon it will be put back on Gibraltar Road at 2500' elevation where coverage will be even better. Give it a try on 145.750 MHz SIMPLEX. Just send a 1750 Hz tone for 4 seconds and transmit your picture or wait for the last picture received to be retransmitted. If you haven't tried Slow-Scan TV, you ought to. It's lots of fun and one of the easiest, least expensive specialized modes of operation. You probably already have everything you need except for a free software download of MMSSTV (go to http://mmhamsoft.ham-radio.ch/mmsstv/index.htm). If you want to know more, check into the SBARC ATV Net at 7:30pm Tuesday on 146.79 MHz. I look forward to seeing you on ham radio, Rod, WB9KMO
