Annual elections were held at the well attended club meeting on November 20th, 2015 to elect the SBARC Board of Directors for 2016. As there were no nominations from the floor, Darryl KF6DI made a motion that the club accept the proposed slate. The motion was seconded by Dave K9KBX, and carried after majority approval by the members present. The newly elected officers and directors are Brian Milburn K6BPM President and CEO, Tom Saunders N6YX Chief Financial Officer (CFO), Dorothy Oksner K6DSO Secretary, and Directors at Large Theo Howe KK6YYZ, Levi Maaia K6LCM, Frank Dambach K6FLD, and Jay Hennigan WB6RDV. The new board will continue to move SBARC forward with new faces, new ideas, and new enthusiasm. We look forward to 2016 being another year of progress for amateur radio in Santa Barbara.

Over the past few months, Bill (W1UUQ) and Levi (K6LCM) have been working on a system to receive position information from aircraft flying over Southern California and the Central Coast using the Federal Aviation Administration’s Automatic Dependent Surveillance – Broadcast (ADS–B) system. Similar to the APRS and AIS protocols which allow for the tracking of mobile amateur stations and ships at seas respectively (both also supported by SBARC sites) , ADS-B is part of the FAA’s NextGen plan to more accurately track aircraft in busy airspace and provide better cockpit situational awareness for pilots. ADS-B position reports are sent unencrypted by many commercial aircraft and by some private aircraft.  The FAA has issued a mandate for all aircraft flying in the vicinity of medium and large traffic volume airports to carry ADS-B equipment by 2020.

Using a Raspberry Pi microcomputer, a USB software defined radio (SDR) dongle and open source software designed to receive ADS-B data signals broadcast on 1090 MHz, the SBARC ADS-B receiver is receiving position data from the SBARC site at Santa Ynez peak. From the mountain, the data is sent via microwave to the club’s La Vigia repeater site on the Santa Barbara Mesa. From this prime location at about 4,300 feet above sea level, the receiver directly detects nearly 1,500 individual aircraft per day flying in airspace from Fresno to Mexico. This is such an incredible reception location it was not a surprise to learn that the official FAA ADS-B site for transmission and reception of ADS-B signals for air traffic control is also located atop Santa Ynez Peak.

SBARC is feeding ADS-B data to Flight Aware and adsbexchange.com.  Both sites make data received by many worldwide receivers available to the general public, however adsbexchange.com provides live data access, while Flight Aware delays position reports by several minutes.
