AMSAT: Amateur Radio Satellite ARISSat-1/KEDR is Deployed - Amateursatellit ARISSat-1/KEDR in Betrieb gesetzt

 The ARISSat-1/KEDR space craft was deployed from the ISS at 1843Z on August 3 after a hold based upon questions about the 70cm antenna. Congratulations to the ARISSat-1/KEDR team! Now bring on those reception reports. The satellite will be in High power mode (continuous transmission) when in the sun and go to Low power (40 seconds transmit/2 minutes idle) mode when in eclipse.

AMSAT Information:

145.950 MHz FM Downlink

FM transmissions will cycle between a voice ID as RS01S, select telemetry values, 24 international greeting messages in 15 languages and SSTV images. One of the messages will be a conversation between Yuri Gagarin and ground control.

If you successfully receive the SSTV transmissions, you are invited to upload your picture to
to the ARISS SSTV Gallery.

145.919 MHz CW Beacon

The CW transmissions will be callsign ID RS01S, select telemetry, and callsigns of people actively involved with the ARISS program.

145.920 MHz SSB BPSK-1000 Telemetry
The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q to be readable in low signal level conditions. The BPSK data will transmit satellite telemetry. When the CW2 beacon on 145.919 MHz is active this indicates that the BPSK-1000 format is being transmitted. If the CW1 beacon on 145.939 MHz is active this indicates the backup of BPSK-400 format is being transmitted.
