All,
Thanks for the tracking on RAX-2. Everything is looking great.
Could you try tracking MCubed next? We have been unable to hear so far.

Jamie,
weak signals from AubiSat and M-Cubed, strong from RAX and E1P (good
decoding).

Bob, You might want to consider a Helical antenna for your mobile
station. It would have less wind drag and easier to rotate.

Actually, I'm beginning to think we will build our own dish. I have a 5'
solid metal dish. I think we will just use it as a form and lay in some
copper strips evry 4 inches or so in one dimension, then overlay say, #12
copper wire every 1" in the other direction, and then solder each crossover
point.
The result will be a linear polarized 4' dish with very low aerodynamic
crossection. A little structure behind it and is it should handle 70 MPH
easily.
I think 1/4" wide copper strap is used for winding some big motors, and
should be easy to find. Using the flat strap for the supports gives a nice
soldering cross point.
We need the 4' dish to close the link when the balloon is 20 miles up. I
dont think we can get that with a helix. My guess is the dish will give us
about 24 dBi vertically polarized with a beamwidth of about 10 degrees?
