AARC meets every third Thursday monthly 12 noon at AARC Shack, talk-in 146.445 simplex.
Meeting will be at 12 noon at Ames Amateur Radio Club station. Talk-in 146.445 MHz simplex.
The Santa Clara Emergency Wireless Network (SCEWN) project, driven by Craig Anderson and Andrew Brown, established Megabit speed radio data links between the emergency operations centers of NASA, San Jose City, Cupertino City, Santa Clara County, and the San Jose Water Company and most recently, the NASA Ames Amateur Radio Club.
Such wireless datalinks enable applications as diverse as the internet itself including web services, forms, instant messaging, file transfer, voice over ip, digital video, or social media, but without reliance on public internet infrastructure. For comparison of SCEWN to Amateur Radio, click link.
Craig and Andrew will describe the current state of the network and its capabilities, which NASA AARC can utilize directly from the NA6MF radio station as part of the NASA-Ames emergency communications program, and will answer any questions. They will also discuss current projects, ambitions and the many future opportunities to consider.
SCEWN was a pilot project whose future development now lies in the hands of ARES/RACES groups. At the forefront is San Jose RACES where Craig is the digital communications chief.
Craig Anderson in January 18, 2007 presented Emergency Wireless Network at AARC Meeting. The EWN project is intended to bring a high speed, scalable wireless communications network with modular capabilities to the Bay Area. It will be used by many first responder organizations including local RACES groups and Emergency Operations Centers. Craig is the Coordinator of SVWUX - Silicon Valley Wireless Users and Experimenters, http://www.svwux.org
Other amateur radio operators are working on similar systems, such as broadband mesh networks at http://www.broadband-hamnet.org

NASA Announces Fifth Round of CubeSat Space Mission Candidates
Amateur Radio Participation in LADEE Lunar Science
LADEE is a robotic mission that will orbit the moon to gather detailed information about the lunar atmosphere, conditions near the surface and environmental influences on lunar dust. Since the Earth and the Moon travel together through space, encountering streams of debris together, observations of meteors in the Earths atmosphere can allow us to make inferences as to what is happening on the lunar surface.
While meteor counts from visual and video observations will provide useful data and a way for the general public to participate in the science of the mission, counts made by radio observers listening for reflection events provide some unique advantages for the mission, as well as, some unique opportunities to experience and participate in a different, unique, mode of radio communications for research; forward scatter meteor detection.
Ames hosted Science Night featuring LADEE on September 6, photos of this event can be seen at Ames AILS site
ISS Slow Scan TV active
Transmissions began late Oct 2013. See http://amsat-uk.org/2013/10/28/iss-slow-scan-tv-active/
All you need to do to receive the SSTV pictures from the space station is to connected the audio output of a scanner or amateur rig via a simple interface to the soundcard on a Windows PC or an Apple iOS device, and tune in to 145.800 MHz FM. You can even receive pictures by holding an iPhone next to the radios loudspeaker.

145.585 MHz was used before but no longer. It is considered a special use frequency and noted as the meteor scatter frequency.
Full list of countywide frequencies can be found at http://www.scc-ares-races.org/freqs/freqs.html
Tactical channels are considered for ARES and RACES activities, Event is used for special purposes such as club meetings, NASA-TV re-transmissions. Command is AARCs repeater, and two packet frequencies are used with County and city EOC message handling.
AARC Continuing Meetings
AARC meets every third Thursday monthly at AARC Shack, talk-in 146.445 simplex.
The club is continuing a series of technical presentations on amateur radio. This is not only for people who already have a ham license, but for those who might be considering getting into amateur radio. There are many applications of ham radio that are not only interesting and useful, but which are also essential in emergencies on land and at sea. The first presentation was an overview of using high frequency (HF) radio on sailboats for voice and email communications. Future technical presentations may include presentations on bouncing signals off meteor showers (meteor scatter), digital communications, and how to get your amateur license.

Receiving K6BEN in south San Francisco bay area
K6BEN video repeater is on 427.25 MHz, same frequency as cable channel 58. To receive K6BEN, set your TV set to cable channel 58, connect a UHF antenna (vertically polarized) aimed at Loma Prieta. Recommended antenna is a UHF (70 cm) yagi antenna.
