I uploaded the RF recordings from last night's pass of the XW-2 satellites
around 0040-0100 UTC to my Dropbox space. They are at:


Look for the filenames starting with HDSDR_20150925. There are two files,
as HDSDR split the recording when the initial file reached the size limit
I set (3800 MB). I ran this for about 20 minutes, since these satellites
are now spreading out, and XW-2A was audible several minutes before the
others, and XW-2E was audible a minute or two before XW-2F.

Even if you don't use an SDR receiver, you can still download HDSDR at
http://www.hdsdr.de and install it on your computer, then download the
RF recordings like those I have been posting. You can use HDSDR to play
back the recordings, and see/hear what was going on during the pass.
Using last night's pass as an example, you'll be able to see/hear the
digital and CW telemetry from XW-2A early in the first recording. Later,
as the other satellites move in range of my station, you'll hear the
telemetry from those satellites. XW-2E is heard a minute or two before
XW-2F is in range, and with these two satellites you'll hear the two
telemetry beacons as well as the transponders. If you worked either of
the transponders last night, you can see/hear if my station copied your

I have RF recordings from other passes I have recently worked, along with
photos and other files, in my Dropbox space. I reorganized many of the
files into separate subfolders. All of this is accessible at:
