AARC May 16 Meeting - PhoneSat Presentation
PhoneSat team will be presenting an overview of the PhoneSat project as well as the results of PhoneSat's recent orbit with an emphasis on radio communication at the Ames Amateur Radio Club (AARC) May meeting.
Meeting will be held this Thursday, May 16th, starting at Noon in the AARC Club radio station (NA6MF). Presentation will begin at approximately 12:15PM, after a short AARC status and business meeting; 2013 AARC dues will be being accepted.
Engineers and interns at NASAs Ames Research Center, Moffett Field, California, successfully collected packet data following launch of Phonesat on a Antares rocket April 21, 2013. These small cubesats were designed and built under Ames Research Centers Small Spacecraft Technology Program since 2011.
Phonesats transmitted health status and image data on amateur radio frequency 437.425 MHz using packet (AX.25). Amateur radio operators that receive these packets contributed to the project by submitting them to Phonesats packets page at http://www.phonesat.org/packets.php.
Three PhoneSats were named Alexander, Graham, and Bell. Graham and Bell. Picture packets were stitched to restore complete Earth pictures, which is why they needed as many packets as possible.
NASA Successfully Launches Three Smartphone Satellites news release at
NASAs PhoneSat project demonstrates the ability to launch the lowest-cost and easiest to build satellites ever flown in space - capabilities enabled by using off-the-shelf consumer smartphones to build spacecraft. NASA engineers kept the total cost of the components to build each of the three prototype satellites in the PhoneSat project to $3,500 by using only commercial-off-the-shelf hardware and keeping the design and mission objectives to a minimum for the first flight.
For more on Phonesat, see http://www.phonesat.org,
and a youtube video.
Amateur Satellite Information
Getting Started with amateur radio satellites
ARISS Packet How To
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.
Amateur Television from AARC
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.

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.

International Space Station Amateur Radio Communications
ISS has an onboard amateur radio station though ISS crews do not have much free time for ham radio activities. Most radio traffic is APRS. You can contact or listen to ISS crews using amateur radio 2 meter frequencies, and handhelds should have good signal quality.
145.800: Worldwide downlink for voice
144.490: Region 2 and 3 voice uplink (The Americas, and the Pacific)
145.825: Worldwide packet uplink/downlink (1200 baud)
145.800: Worldwide SSTV downlink
145.200: Region 1 voice uplink (Europe, Central Asia and Africa)
437.800: Worldwide uplink for cross band voice repeater, downlink 145.800
Voice repeater (worldwide): downlink 145.800, uplink 1269.650
Voice repeater with PL (worldwide): downlink 437.800, uplink 145.990 with PL 67.0
Occasionally, the amateur radio gear onboard would be configured as a repeater. Click here for more info.

Jupiter can be heard on a shortwave around 18-22 MHz. Use a loop antenna over a ground plane reflector. Solar flares can be heard on a VLF reciever at 27 KHz. A good book to get is Radio Astronomy for the Amateur by David Heiserman and the Amatuer Radio Astronomers Handbook by John Jotter Shields.
