Hi Luc,

TLMEcho is the program for LIVE decoding of AO-51 telemetry packets
during a pass.  Some telemetry channels are sent via 9600 baud packet
at a regular interval, usually 10 seconds, and TLMEcho can decode
these (using a 9600 baud modem) LIVE as they are coming down.

The new WOD decoder is different--it is used to decode satellite
telemetry data collected (more channels usually) and stored on the
satellite during a whole orbit (usually set for 24 hours).   Once the
WOD file is finished, it appears on the PBBS and can be downloaded via
WISP.  The downloaded WOD file can then be decoded by DK3WN's new
program after it has been downloaded from the satellite as a big file
(about 180k).

I hope that helps clear things up :)

Hi Mark

Is it a new program or a new update for "tlmecho"? I guess it's a new
one but just to be safe.
