New 2-Meter Repeater
by Bill Talanian 29 May '12

29 May '12

29 May 2012 To: SBARC List-server clients From: Bill Talanian, Director, Trustee Subject: New SBARC Repeater New 2-Meter Repeater on La Cumbre Peak A new 2-Meter Repeater has just been installed at La Cumbre Peak. It is operating on 147.705 output and 131.8 PL. SBARC-SBTAC will be testing the next generation APCO P25 technology which Public Safety is deploying nationwide. Our technology team will be playing an important part in the local Test & Evaluation (T&E) of this new standard for Public Safety. The system can handle both standard FM and P25 in wide-band mode. When the system is transmitting P25 there is no intelligibility to users listening on a standard FM comm radio. Just a squelch break and digital pulses. Users with P25 capability are requested to check with the technology team listed below for purposes of conducting tests and data collection. Users are reminded that we are under test. All matters pertaining to over the air discussion about coordination or other open announcements should be curtailed. Please contact the Trustee or any of the test coordinators listed below for technical assistance. P25 compatible user team: W6AMS KD6VEX W6KGB

IRLP demo Saturday
by Paul Ryack - W1PR 22 May '12

22 May '12

If anybody is available on Saturday May 26 at 7:30 PM local, a teacher at an American military school in Seoul, S Korea, would like to give a demonstration of IRLP to his ham radio class. His name is Rich, and his call in S Korea is HL1ZAR. He uses IRLP node 3510 and will be trying from about 7:30 to 8 pm our time. I don't expect to be near a radio at that time, so if somebody with a 440 FM radio could listen for him to call our node(or call his) I know it would be appreciated. 73 /prr -- Paul R.

Thanks to local hams for help with Anacapa School's Near Space Flight
by Levi C. Maaia 11 May '12

11 May '12

Some of you may have already received this, so if this is a duplicate message, I apologize. Below is a summary of the a high altitude balloon project with amateur radio technology that I worked on with my students at Anacapa School this year with support from SBARC members. Many thanks to Rod, WB9KMO and Cyril, AF6GW and Alex, KJ6FAF for their help getting live Amateur TV working on this probe and for outfitting the SBATV-mobile with a grid dish for a live video downlink. Also thanks to Bill, W1UUQ and Shaw, AE6BL for making sure that our local APRS system was in tip-top shape for live GPS tracking and weather reports from 111,814 feet over Santa Barbara and Kern Counties! See the story below and watch the video from the on-board HD video camera on YouTube at: http://youtu.be/Sw7wSPdR3-U Levi K6LCM Anacapa School’s Near Space Probe Soars 111,814 Feet Over California Student-built, homebrew weather balloon probe returned live video and data during three-hour flight AAHAB-2's on-baord camera systems captured images as it climbed to 111,814 feet above the Earth's surface. May 7, 2012 — Santa Barbara, Calif. Members of the Anacapa Near Space Exploration Club (ANSEC) at Anacapa School are celebrating the weekend success of their second near space probe Anacapa Amateur High-Altitude Balloon 2 (AAHAB-2). The high school team launched two payload capsules tethered to a weather balloon on Saturday, May 5 at 6:52 a.m. from a site off Highway 166, northwest of New Cuyama, Calif. The sunrise launch afforded the team some tremendous photo opportunities. This images shows the balloon's view climbing through 26,444 feet. Equipped with GPS, atmospheric sensors, high-definition video and still cameras, a television transmitter and a Geiger counter, AAHAB-2 downlinked live data, video and images to the crew during its ascent. As the balloon climbed through the thinning air, the decreasing atmospheric pressure caused it to expand nearly ten times in diameter. Upon reaching its apex above California’s Central Valley, the balloon burst, sending the payload back to the surface under the canopy of a small parachute. By reaching an altitude of 111,814 feet, AAHAB-2 shattered the record of the group’s own AAHAB-1 flight by more than 20,000 feet. AAHAB-2 was designed and built entirely by Anacapa students Grayson Baggiolini, Julio Bernal, Alex Carlson, Christian Eckert and Genevieve Hatfield under the supervision of their faculty advisor Levi Maaia. The team has been working on the project since September 2011. Carlson, an 18-year-old senior at Anacapa, and Hatfield, a 15-year-old sophomore, earned their amateur radio licenses, allowing the group to use specialized higher-power wireless equipment to transmit live video images and data from the capsule to the ground crew throughout the flight. With the support of members of the Santa Barbara Amateur Radio Club, the Anacapa crew watched the live television downlink as the balloon climbed through the freezing, harsh conditions of the upper atmosphere into the dark, eerily-silent skies of near space. AAHAB-2 was recovered from a ranch near Bakersfield four and a half hours after launch. “I am confident in saying that AAHAB-2 was a success,” said Carlson, the mission’s flight director. “There are some things we would do differently next time around, but overall we accomplished more than I ever expected.” The craft’s three-hour and 18-minute flight was about one hour longer than the team anticipated, causing some moments of anxiety as they watched position reports creep eastward toward the Sierra Nevada. “Our initial projections showed that it would touch down near Taft,” said Eckert, a 16-year-old junior. “We never expected it to climb so high and stay there for so long!” Fortunately for the crew, the descending capsules landed just short of the ridgeline, touching down in ranchland at the base of the foothills south of Bakersfield. The students expect to thoroughly document the flight and analyze the collected data over the coming weeks. More information, including additional photos and a condensed version of the in-flight video on YouTube can be found online at www.anacapaschool.org/ansec. Anacapa School is an independent, co-educational, WASC–accredited, college preparatory day school for students in grades 7-12. Founded in 1981 by Headmaster Gordon Sichi, Anacapa enjoys the best student-teacher ratio of any school, public or private, in Santa Barbara at its historic campus located in the heart of the Santa Barbara civic center.

SBARC team solves worldwide aprs problem
by Bill Talanian 05 May '12

05 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.
