SBARC team solves worldwide aprs problem
by Bill Talanian 06 May '12

06 May '12

SBARC Tech's Help Solve Global APRS Flaw It all began when Levi Maaia, K6LCM, was engaged with yet another of his stratosphere weather balloon experiments at the Anacapa School. An experimental sensor array data feeding a Byonics TNC to the SBARC APRS 144.39 system turned into unexpected results. Levi soon discovered a reporting flaw on the aprs.fi global reporting system. He noticed his WX data wasn't showing up on aprs.fi, but it was showing up on findu.com. The issue quickly got the attention of Shaw Takeuchi, AE6BL, of SBARC, Heikki Hannikainen (Hessu) in Finland who is the author of aprs.fi as well as Pete Loveall, AE5PL, author of javaparssrvr. Lead troubleshooter was Lynn W Deffenbaugh (Mr), KJ4ERJ, author of APRSISCE for Windows Mobile and Win32 who was assigned to the case. It was discovered that the global complex network of data servers in multiple layers had two servers which were misconfigured causing the system to drop WX data coming from APRS. Worldwide flash emails were going back and forth this week to help nail down the heretofore undiscovered flaw in the system. With Levi discovering the problem and Shaw defending the SBARC configuration it focused the the worldwide experts on solving the server problem. There is much more detail to this story which hopefully can be documented for a good Key-Klix article. You guy's did a GREAT JOB of global team work in communicating the data back to the authors in solving their undiscovered problem.

30 Apr '12

Registrations are now being accepted for USA's annual championships of on-foot transmitter hunting, which will take place during the week and weekend after Memorial Day. The site will be the forests near Mt. Laguna Village, about 45 miles east of San Diego. Activities will get under way on Wednesday and Thursday, May 30 - 31, when an optional two-day "training camp" will take place. The official championships opening will take place on Friday, June 1 with practice and equipment testing sessions. The two-meter contest will take place on Saturday, June 2, after which all will gather for a banquet in the evening. Sunday's schedule includes the 80-meter contest and an awards ceremony, timed to end in mid-afternoon to accommodate those who must hurry home. Even if you have never competed in a formal ARDF event before, you are welcome at the USA and IARU Region 2 Championships. The courses will be open to all, beginner and expert alike, with or without a ham radio license. USA's best are expected to attend and they are always helpful to newcomers. The training camp is an outstanding opportunity and highly recommended for first-timers. National ARDF Championships are for individuals only. No teaming or assistance on the course is permitted. Participants are divided into six age categories for males and five age categories for females in accordance with standard IARU rules. Medals for first, second and third places will be awarded in each category on each band. The official event Web page at www.homingin.com has the registration form. It is important for participants to register right away. The organizers need an accurate head count and assurances that there will be sufficient attendees. It's also important to make reservations now if you want to stay at the event headquarters, which is Laguna Mountain Lodge. (Nearby camping is also available.) Transportation and lodging information is on the event Web page, as well as the daily schedule, competition rules, transmitter and map information. For questions and regular updates, you can subscribe to a group mailing list for participants and others interested in these championships. If you have been attending and enjoying our local ARDF sessions, it's time now to take the next step. We look forward to seeing you at the USA Championships!

by Marvin Johnston 20 Apr '12

Southern California's next ARDF session will be Saturday, April 21 at Lake Los Carneros Park in Goleta. In addition to the beginner-to-intermediate level ARDF course, there will be a workshop for building measuring-tape antennas and attenuators.

Hunters may start out on the courses at any time until 1 PM. Courses close at 2:30 PM. The site area is slightly less than 140 acres. It is relatively flat, making it a good site for foxtailers of all skill levels. If you need some one-on-one help to get started at finding transmitters, just ask. Full-color orienteering maps will be available. Directions to Lake Los Carneros: From US 101 about 8 miles west of downtown Santa Barbara, take the Los Carneros Road exit, head north about 1/4 mile and turn right into the Stow House parking lot. There should be plenty of free parking. Look for the orange-and-white orienteering flag. The building session and hunt start will be in the picnic area, just east of the railroad depot. For your GPS navigation system: 300 North Los Carneros Road, Goleta, CA, 34.44416N 119.85446W. Ham radio talk-in is on the WB6OBB repeater, 147.000(-) PL 131.8. 73, Joe Moell K0OV

SBARC Club Meeting for April 20, 2012 by Darryl Widman, KF6DI, SBARC Program Chairman SBARC on Santa Ynez Peak and Other Places with our own Bill Talanian, W1UUQ, Chairman SBARC Telecommunications Committee Up on the ladder is Steven Nelson, KD6VEX, one of the good guys who freely gives of his time and effort in behalf of Amateur Radio and the Santa Barbara Amateur Radio Club. Bill Talanian, W1UUQ, our Chairman of Telecommunications lives and breathes repeaters, mountain-tops, co-ordinating radio communications with public service agencies and setting up radio operations for these groups. It is fine people like this who continue to give the Santa Barbara Amateur Radio Club its good name. Bill can always be found, if you know where to look for him, planning, discussing, organizing, putting up and tearing down anything having to do with telecommunications in our general area. This Friday at our club meeting, you will find Bill in the front of the room telling us about what SBARC is up to regarding radio communications in our behalf (or someone else's) and is always anxious to answer questions in as much detail as he feels we can comprehend! Along that line, Bill is always looking for good, able-bodied folks to lend a hand, roll up their sleeves, help raise/lower structures for radio communications and, generally, get involved with getting good, clean signals from here to there. Come to our April 20, 2012 club meeting and learn more about what Bill and his team of good guys are up to lately. Please bring some goodies for the refreshment table. It will be appreciated. Remember that the Santa Barbara Amateur Radio Club holds its monthly club meetings at the Goleta Union School District, 401 No. Fairview Ave. in Goleta, right across the street from the Goleta Library. It all begins at 7:30 PM but come early to meet a whole lot of good people and also, see what others brought for the Free-To-Good-Home table. Please bring yours and remember to take it back with you if no one wanted it! ____________________________________________________________ 53 Year Old Mom Looks 33 The Stunning Results of Her Wrinkle Trick Has Botox Doctors Worried http://thirdpartyoffers.juno.com/TGL3141/4f8b9faa63e505ef8f4st05duc

I came across this while learning more about Fourier analysis and thought it might a hidden gem, and less the article is less than a year old (Dec. 2011). The last section on ferrite loaded cavities, for variable resonance, especially caught my eye. If the attachment does come through, here's the source link: http://www.adams-institute.ac.uk/resources/graduate_lectures/ted_wilson/Lec… :-) neil KE6DCJ
