Very nice, Bruce! What a great project.
In the video you mention something about CW--is that an ID for the bird currently being tracked, or what? I might have missed it...
Correct. The tracker announces the bird in CW as it rises and sets, and it periodically announces its azimuth and elevation, like 'HO68 WSW H[igh]'. The final product is potentially so very small that I didn't want a display screen to increase its size unreasonably.
What it *doesn't* do is provide any prediction. I figure you can print out a chart of these things, or just take pot luck as the tracker scans through the 10 or so birds for which its EEPROM provides space.
You can hear the CW announcement during the QSO at the beginning of that video, but a clearer indication is 47s through this video: http://www.youtube.com/watch?v=XgNcCGXeRyw
What the spectran view in the video shows is how the tracker stops tuning the radio while it is announcing in CW, causing doppler shift briefly to take over. I need to rewrite my CW library so that it calls the tuning function during the elements that are long enough to allow it, such as spaces between words.
