While the bandwidth lasts, you can download some recordings of KP4AO here:

http://www.sonic.net/~hartzell/kp4ao/

These are made from the NASA Ames Research Center station (NA6MF, CM87).
Our setup was a 22' antenna (with a 22 dB, 0.5 db NF pre-amp). We were only
about 100W into the antenna. The after-the-fact analysis done by K1JT
reveals that we made it into Arecibo, but we didn't get a full QSO.

The WAV files can be opened in WSJT, or SpectraVue, WinRad, Audacity, etc.
Some of the files are JT65B, some CW, and some voice. All files were
recorded with WSJT 7.
