_1600utc_436.255cw.mp3

Burst of 5 seconds, within a period of 20 second.

He estimates that the center frequency of AggieSat is around 436.255 MHz
First signals heard 436.262, last signals 436.248.

Henk also reports hearing ANDE Castor and capturing some telemetry  from ANDE Pollux.

After decoding the telemetry Ivan Galysh, one of the development team, posted:

"Current surface temperature is ranging from 6 to 9C. Interior temperature is ranging from -3 to -1C. It looks like all high school MEMS experiment payloads are functioning.
Some of the data doesn't look right but that is part of the experiment. When I get a chance, I'll send out the MEMS telemetry format and info on the MEMS devices."

At the time of writing (July 30 1900 UT) no signals from BEVO1 had been reported.
