Decoding table for TIsat-1 early beacon messages
During the early days of TIsat-1 mission, the beacon send continuously
during the day the message "HI HI HI TISAT" followed by a Morse character
indicating the temperature of the transmitter. The beacon is turned off
during eclipse to avoid stress of the batteries. This message is repeated
each 15s and is encoded with 17 WPM. The radio used as beacon has been
developped completely in SUPSI with the help of local HAMs.
The following table allows to translate the last character of the message
into the relative temperature expressed in Celsius degrees.

We invite to keep note of the received messages and temperatures.
A Web application to upload these information will be soon available.
