Because of heavy traffic to the website, I'm putting this general description of the SkyQuest telemetry format here before even I know all the details.

One thing that is final is the 60 second cycle ( click for color graphic). It will hold for several hours with an error of a fraction of a second, and will make it fairly easy to tell what you're hearing at any given time.

The two temperature channels will monitor the interior instrument temperature and the outside air temperature. The audio tone transmitted during temperature phases of the cycle (4 outside and 1 inside every minute) will vary in frequency in the following way. A high frequency will indicate a high temperature, and a low frequency a low temp. The endpoints are roughly 220 Hz for -60 degrees Fahrenheit (which will probably be reached, or close to it!) and 3200 Hz at +85 F.

The altitude is a little tricky in that the tone frequency doesn't directly correspond with altitude. What does tell altitude is the number of times since launch that the tone has changed between 1000 Hz and a higher value of about 3000 Hz.

The 1000 Hz tone is a reference tone that indicates drift in the instrument frequency generator and can be used to correct the other channels if necessary. If there is no drift, the 1000 Hz will stay put.

Morse code, including the ID of N1LTV, will occur at intervals of 5 minutes superimposed on the second altitude segment beginning at 20 seconds. So the frequency of the code tone will be the telemetry frequency.
