REMEMBER SUITSAT? Three months ago, ISS astronauts hurled an old Russian spacesuit overboard. Amazingly, it is still orbiting Earth. On April 18th, Kevin Fetter videotaped "SuitSat" passing over his home in Brockville, Ontario, Canada: 1 MB movie. (The bright star in the movie is Vega.) Eventually, SuitSat will sink into Earth’s atmosphere and disintegrate in spectacular style–a fireball–but not yet!
The film is here:

Annual meeting in Stockholm.
Lite information om QRP FM-repeater på AO-51:
This year, AO-51 will be setup in dual FM repeater mode, allowing for two usable FM repeaters from the satellite. The FM repeater utilizing the transmitter on 435.300 will be open to all users. The FM repeater utilizing the transmitter on 435.150 (normally reserved for BBS
operations) will be reserved during Field Day for QRP stations only, as has been the common practice when this mode runs on AO-51. Please note the information on the mode configurations and QRP requirements.
FM Repeater #1 for all Users:
Downlink: 435.300 mhz FM
Uplink: 145.920 mhz FM
FM Repeater #2 for QRP Users ONLY:
Downlink: 435.150 mhz FM
Uplink: 145.880 mhz FM
AO-51 ECHO LOW POWER STATION (QRP) REQUIREMENTS:
To attempt to keep this simple, a low power station will be defined as a station which can deliver no more than 10 watts to a vertical or handheld antenna. These are some examples of Low Power Stations:
* Using an HT (barefoot, no amplifier) with 10 watts or less output into any type of vertical whip antenna (rubber duck, etc) or handheld beam antenna (arrow type).
* Using a mobile station with 10 watts or less output into car mounted mobile whip antenna(s).
* Using a base station at 10 watts output into a vertical omni-directional antenna on the side of the house.
Examples that are NOT Low Power Stations:
* Any type of high gain beam antenna, KLM, M2, Cushcraft, etc.
* Any station transmitting over 10 watts into any type of antenna.

CT1DMK har lyckats med konststycket att ta emot Voyager1 på sin hemmaparabol. Avståndet är 98 AU = 98x avståndet Jorden/Solen.
Space probe VOYAGER 1 successfully received On March 31st, 2006 an AMSAT-DL /IUZ team received the american space probe VOYAGER 1 with the 20 m antenna in Bochum.
The distance was14.7 billion km. This is a new record for AMSAT-DL and IUZ Bochum. The received signal was clearly identified through means of doppler shift and position in the sky. The receive frequency was exactly measured and compared with the information provided by NASA.
This distance equals approximately 98 times the distance between Earth and Sun. VOYAGER 1 is the most distant object ever built by mankind. This again proves the superior performance of the Bochum antenna. Most probably this is the
first time Voyager 1 has been received by radio amateurs.
VOYAGER 1 was launched on 5. September 1977 by NASA. It transmitted the first close-up pictures of Jupiter and Saturn. In 2004 VOYAGER 1 passed the Termination Shock Region, where the solar wind mixes with interstellar gas.
VOYAGER 1 today is still active, measuring the interstellar magnetic field.
The following radio amateurs were involved:
Freddy de Guchteneire, ON6UG
James Miller, G3RUH
Hartmut Paesler, DL1YDD
Achim Vollhardt, DH2VA/HB9DUN
Special thanks to Thilo Elsner, DJ5YM of the IUZ Bochum, Roger Ludwig of Jet Propulsion Laboratory (JPL), Pasadena USA and the Deep Space Network Tracking Station in Madrid, Spain for their cooperation.
