Ham Radio Satellite

Catching satellites on ham radio | MAKE

The Thailand Amateur Radio Satellite Group are developing their first satellite JAISAT-1.

The group hope to complete the satellite, a 1U CubeSat, by the end of 2015. Plans include a 145 to 435 MHz linear transponder for SSB/CW communications, APRS, a packet bulletin board system (PBBS) and a HD camera for imaging.

The Radio Amateur Society of Thailand (RAST) carries an article about the satellite on their English language website at

The group are looking for a circuit diagram of a 145/435 MHz linear transponder. Anyone who can assist them with the transponder should contact the JAISAT-1 Project Manager Tanan Rangseeprom HS1JAN, email: hs1jantamsat.org

At the present time no arrangements have been made for a launch.

Black Knight Satellite

What is the "Black Knight" satellite? It is a mysterious satellite, of unknown origin, discovered in 1960 which shadowed Sputnik.
It is believed to have been of extraterrestrial origin, and signaled back old radio waves from the 1920s and 1930s before it disappeared.
In short wave patterns analyzed by astronomer Duncan Lunan, it revealed its origin as Epsilon Boötes (or the star system as it was 13,000 years ago).
In February 1960 the US detected an unknown object in polar orbit, a feat that neither they or the USSR had been able to accomplish

Angeles Crest to Azusa

Is anybody interested in a ride down the closed portion of the Angeles Crest from Baden-Powell to Little Jimmie Trail Camp, then up over the ridge, down into Crystal Lake, then all the way down the 39 to Azusa?
Combine mountain biking, hiking and whatever. You will need a reliable bike and about 4 gallons of water. No yahoos, please, as it would be easy to get killed on this ride. Both the 2 and the 39 are closed, so there will be no evac. Satellite phone or ham radio required. EPIRB or ELT a good idea.
The truly inspired can continue right down the San Gabriel River Trail to Sunset Beach.
