BigRedBee in Space
There are two BigRedBee transmitters currently in low Earth orbit.
The first, launched in 2009, is ITUPSAT1 (http://www.n2yo.com/?s=35935) . It's transmitting CW on 437.225 Mhz. Here is a ground based recording of the transmitter from 2011.
TURKSAT-3U was launch in 2013. (http://www.n2yo.com/?s=39152). It's transmitting CW on 437.325Mhz
If you happen to capture some audio from one of these 70cm beacons, I'd be honored if you shared them with me!
