The second pass was 12 minute with max 30 degree elevation. Signals where stronger then the one from 18:55 max 20db above noise. You can even see and hear some audio tones but unable to decode.

Lower in frequency then was communicated a carrier with very weak audio that sounded like AX25 1200 baud. But there are signals that seem to be transmitted from CubeBUG-1.

A job well done by the CubeBUG team, congratulations.

Later that evening I listened for CubeBUG-1 and recorded an IQ file. This file can be downloaded at the following location: download. This file is recorded with SDRSharp in 16bit PCM baseband format.

Phonesats

Downlink
437.425 MHz

Hello CubeSats and Amateur Radio Operators

The very first PhoneSat’s will be launching aboard the Antares on April 17th at 2100 GMT (launch window to April 19th possibly further). We have manifested 2x PhoneSat 1.0 and 1x PhoneSat 2.0 Beta.

Our orbit is very low (270km x 300km 51.6deg) and we’ll only be up there for 2 weeks! So we’re looking for as many people as possible to help with tracking our satellites. If any of you are interested in tracking the satellite please let myself (+the cc’d team) know – your help will be greatly appreciated!

All three satellites will be transmitting on 437.425MHz and TLE’s + more info can be found at www.phonesat.org . Feel free to tune-in and submit packets via www.phonesat.org.

The Cubesats are launched, deployed and active.
