ARLS005 ARISSat-1 On the Air for Gagarin Anniversary
 
Just FYI. I will be dragging out my yagi and trying to track the ISS for this.

ARLS005 ARISSat-1 On the Air for Gagarin Anniversary

To celebrate the 50th anniversary of the first human spaceflight by
cosmonaut Yuri Gagarin, the ARISSat-1 satellite aboard the
International Space Station will be on the air using the station's
external antenna. Transmissions will begin on Monday, April 11, at
14:30 UTC and continue until 10:30 UTC on April 13.

To preserve the satellite's battery, transmissions will cycle on and
off. ARISSat-1 will transmit for 40 to 60 seconds, and then remain
silent for 2 minutes.

The FM transmissions on 145.950 MHz will alternate between a voice
ID, telemetry values, SSTV images and audio greetings in 15
different languages. One of the transmissions will contain audio of
a conversation between Gagarin and ground controllers that was
recorded during the historic flight.

A CW beacon will be heard on 145.919 MHz cycling between the
ARISSat-1 call sign, telemetry and call signs of individuals
involved in the ARISS program.

BPSK-1000 telemetry transmissions will also take place on 145.920
MHz SSB using the new 1kBPSK protocol developed by Phil Karn, KA9Q.

AMSAT will issue commemorative certificates to listeners who receive
the ARISSat-1 transmissions. Reports can be e-mailed to
Gagarin@arissat1.org or yuri@arrisat1.org. Include your name, call
sign, a description of what you heard and the UTC time you heard it.
Recording the battery voltage telemetry values and the UTC time you
received them will be especially helpful.

You can determine when the International Space Station will be
passing overhead by using the AMSAT-NA online pass prediction tool
at, http://www.amsat.org/amsat-new/tools/predict/.

Tried a couple of times, never heard it. Trying to figure out what happened, but the current crew on the ISS isn't as interested as some in ham radio so someone probably just forgot to turn it on. :-)
