Ames Amateur Radio Club activity during Open House
October 18, 2014
As a Federal Reserve, use of any radio wave emitting devices on Moffett Field, with exception of cell phones, are subject to advance approval and permission for use by the Ames Spectrum Management Office. This guidance is comprehensive and includes, FRS/GMRS radios, CBs, commercial radios, drones, quadcopters, other remote-control devices and vehicles, other licensed and unlicensed devices, and Amateur Radio devices not coordinated through the Ames Amateur Radio Club.
In recognition of the value added role Amateur Radio provides in expanding situational awareness at large public events, for this event, Amateur Radio Operators are anticipated to be allowed to bring their Amateur Radios on site for use with the following understandings:
NOTE: From a cellphone or phone patch, 911 will be redirected inhouse for faster reponse within Ames. Moffett Field Dispatchers can be contacted directly at 650-604-5555.

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.

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.

ISS Slow Scan TV active
All you need to do to receive the SSTV pictures from the space station on 145.800 MHz FM 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.
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.

Club members also support a wide variety of HF, VHF, and UHF communications modes for educational and recreational purposes as well as provide voluntary public service and emergency communications support to Ames, Santa Clara County, and special events occurring on the Moffett Field complex.
The AARC is coordinated with the Silicon Valley Emergency Communications System (SVECS at http://www.svecs.net), an ARES/RACES association. AARC cooperates with other ARES organizations in the Santa Clara County, http://www.scc-ares-races.org
The club station, NA6MF, is affiliated with the Amateur Radio Relay League (ARRL) http://www.arrl.com.

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.
