The most important information this morning is from the PI, Zac Manchester: "We've now been able to decode some telemetry data from KickSat-2 and can confirm that the CubeSat is alive and working well aside from a communication issue. It seems likely that the antenna did not deploy properly. We would appreciate IQ recordings from anyone with a large high-gain antenna as we continue trying to establish communication with the satellite (even if the signal is weak and not decodable using standard methods). I'm working on some fancy signal processing tricks to try to pull some useable data out of these very noisy packets." The KickSat-2 cubesat is transmitting telemetry data on 437.505 MHz. The telemetry packets are standard AX.25, 1200 baud FSK (not AFSK). But the signal from Kicksat-2 is very weak. Here is a snippet from Mike Rupprecht DK3WN : KickSat-2 beacons – very weak and his twitter account.

When deployed, the Sprites are on/will be on 437.240 with a weird MSK modulation at 10 mw when the Sprite is in sunlight (no batteries). At the British Interplanetary Society we are trying to set up for the Sprites using receivers as specified here: zacmanchester/kicksat

I'm sure everyoine involved in Kicksat would welcome AMSAT'ers listening out for the cubesat and the Sprites, and joining in the project at the googlegroup. 73 de andy g0sfj
