Around 2010utc on 3 May 2008 I commanded the AO-16 TX A back ON (437.026 MHz). The current power level is conservative, at around 700 millwatts as reported by the telemetry. (It's a bit harder to hear than when it was transmitting at 1.8 Watts!)
Current plans are to leave the satellite in the digital MBL mode for a few days so as to collect telemetry for review. You can hear the satellite "humming" in its 1200 BPSK mode.
Interested listeners of AO-16 can help by copying any telemetry captured via the Warbler sound card demodulator available at http://home.casema.nl/b.ubbels/Warbler.htm. This software is from the same folks that brought you the RASCAL software for Delfi-C3. A file called "warbler.kss" is produced when packets are decoded. These "warbler.kss" files can be sent to n8mh AT amsat DOT org for analysis. Please include your QTH (gridsquare) and the time the telemetry was captured.
Telemetry from AO-16 in the MBL mode is random and infrequent. It's possible to hear no telemetry during an entire pass.
Please do not transmit to AO-16 until further notice.
On behalf of the command team,
Mark L. Hammond [N8MH]
