INVITATION TO JOIN SARC
by Larry Merwin KE6YLG
As is customary, this February issue of THE AIRWAVES is being sent to
every Ham in the Indian Wells Valley and surrounding communities. We do
this to remind everyone that Sierra Amateur Radio Club (SARC) exists
and, bluntly, in hopes of convincing more of you to part with fifteen
of your hard earned dollars to join our club. Me? I'm as big a
skinflint as they come (Just ask my kids.) but I think that the
greenbacks spent on my annual SARC membership are money well spent. I
hope that I can convince you of this as well. Here are KE6YLG's top ten
reasons to support SARC.
MEETING PROGRAM Wed 10 Feb
The program for the February meeting will be a demonstration of the Automatic Packet Reporting System (APRS) given by Jack Bitzer NL7SX. Two laptops, a TV monitor, a video display and a live APRS digipeater will be used. Live statewide APRS activity from 1900-2100 hrs will be shown on the display. The APRS network will be notified of the demonstration by APRS bulletin. Horses, motorcycles, trucks, other mobiles and some UFOs have been seen and tracked in the past. A question and answer session will follow the presentation. How to find the SARC meeting? Just look for the SARC icon on your APRS screen and "come on down."

Rider and horse logging, calling for the veterinarian, finding lost horses, getting the water wagon to its planned location etc. are a few of the things that come up. Anybody gotta bucketa oats? Call Lloyd Brubaker WA6KZV at 375-7245 to participate in this marathon.
Geo Bun Buster Horse Ride Sat 20 Mar

A note about signing up Doing these communications tasks well requires coordination and efficient use of operator experience and available radio equipment. Sign up as early as possible with the coordinators so they can plan efficient use of your capabilities and assets.
RECENT SARC ACTIVITIES
Fire Mountain Fifty Horse Ride
as related by Dave Stone KC6UUR
Nine SARC Hams provided communications, kept track of contestant locations and dispatched supplies for the Fire Mountain Fifty. This is a fifty mile endurance contest for horse enthusiasts sponsored by the Valley Riders and was conducted in the desert hills east and south of Ridgecrest on 23 January.
There were three loops comprising thirty mile and fifty mile rides, three water stops and veterinarian stops on the second and third loops and at base camp, the termination of the three loops. Sixty one contestants finished the fifty mile ride and forty did the thirty miler. A seven year old girl on a pony and a rider on a twenty year old horse successfully completed the thirty mile course. At the awards BBQ they captured the youngest and oldest awards.
Dave Stone KC6UUR, the communications organizer, reports that all went well in the day that started before six am and ended nearly twelve hours later. Dispatch of water, hay and horse trailers to the course, location of riders, veterinary requests, motorcycle race progress and myriad's of other bits of information were passed about the course by the Ham communicators. Using the Ham's contestant logs, location could be ascertained to within half a loop. This information soothed worried team members at main site.
Judy Burns KC6UTF worked one of the busier water stops, the first water stop for loop two and the second water stop for loop three. With a choking horse and the nearest veterinarian three miles away, the horse was ministered to remotely by a veterinarian via third party traffic set up by Judy at the ailing horse, and Dave with the vet at base camp. The horse was kept moving and eventually was well enough to finish the contest.
Another situation that was closely monitored by Bill Burns WA6QYR was contestants in a motorcycle race being held concurrently. The motorcycles crossed the horse trails and, in one location, even used the same trail. Doesn't this bring into mind images from old black and white horse operas of rearing horses and upsetting carriages spilling occupants after being startled by one of those infernal, noisy horseless carriages? The presence of a trail monitor with a radio, good horse sense and contestants in both events being forewarned by BLM avoided any serious incidents, however Bill Burns kept the nervous organizers at main site apprised of conditions.
Greg Roush WA7IRW and his son Ben, assisted by Hal Hazel KM6JM tended to the SARC portable repeater getting it set up and on the air before the first horse was very far into loop one. Greg and Ben then worked the nearby water stop on loop one until it was closed. They then relieved Mark Slay KE6SMA who was watching over a very busy point about a mile out from the start were loops one, two and three split on the outbound leg of the course and then merged on the inbound leg.
Todd Evans W6TOD, assisted by Pam Mathes KC6UUS, worked check point one on loop three. From this location, it was difficult to work the portable repeater. Todd and Greg soon discovered that they could communicate successfully on 70 cm. Greg then setup his mobile radio as a cross band repeater into the SARC portable repeater allowing all the water stops and base camp to communicate.
Hal Hazel covered the second water stop on loop two, also the third water stop for loop three, until Alex Higgins KD6ZUV arrived. When loop one closed and Greg moved, Hal set up cross band for Todd on loop three. Eventually Hal took over at the loop three water stop, and by a combination of high power and a high gain antenna, managed to get into the portable repeater.
In addition to the SARC portable repeater located remotely, the City of Ridgecrest's Multi-Purpose Van with it's generator trailer were set up at main site for extended communications capabilities and protection from natural elements during this twelve hour event. Jerry Brooks, the van's constructor and chief operator, coordinated with Bill Burns for use at base camp. Bill drove it out Friday and helped Dave Stone put it into operation. Bill also assisted with shut down and return to the police station.
Near the end of the day, contestants (the human ones) were asking about the threatening weather ominously spilling over the Sierra Nevada a few miles to the west and what road conditions might be for their drive home. Two Ridgecrest hams monitoring the local SARC 146.64 MHz translator were contacted and asked to check. Up-to-the minute weather and road conditions were supplied hot off the internet by Jerry Brooks KK6PA and Elvy Hopkins NØLV.
This event allowed SARC Hams to get on-the-job experience in solving communications problems. Cross band operation from a handheld to a higher powered mobile transceiver was used by five Hams as they roamed about their assigned check points. Cross band was also used for a relay to the portable repeater. The portable repeater worked flawlessly after it's recent heavy maintenance by Greg Roush. The Multi-Purpose van and generator got a needed periodic shakedown and Jerry Brooks was very proud of it's performance. The local SARC 146.64 MHz translator and the autopatch on the SARC 147.00 MHz repeater were used to contact persons in Ridgecrest. With emergency preparedness in mind, the Fire Mountain Fifty was good practice.
HAM Books to Library
SARC has provided to the Ridgecrest branch of the Kern County Library two more amateur radio books. The first is the current ARRL "General Class License Manual," third edition, with the July 1998 revised question pool covering RF safety.
The second is ARRL's "RF Safety and You." This 316 page tome treats the new RF safety issue in depth with theory, text of the regulations and bulletins, charts, tables and evaluation worksheets.
These additions to the thirty other SARC presented amateur radio books must travel the long and torturous maze of the Kern county library acquisition system before being returned to the Ridgecrest branch.
All Hams are encouraged to visit the library and scan the wide variety of amateur radio books that SARC has provided to the Indian Wells Valley community. Some book subjects are: getting started in Ham radio, license study guides, antennas, transmission lines, equipment construction, satellite communication and the ARRL's two most famous handbooks the "Handbook for Radio Amateurs" and the "Antenna Book."
911 Now Working on 147.00 Repeater
Dialing 911 on the SARC 147.00 MHz repeater's autopatch has not worked since the leading "9" before each dialed number requirement was dropped. Oops! Jim Kusznir KE6DWM, with the help of Mike Hugo KA6OIJ, via e-mails, has remedied this omission.
Jim has also allowed the transmission of touch tones through the phone lines so that local pager 800 numbers can be dialed.
