[aprssig] Inexpensive APRS transmitter kit

[Scott Miller]

And an APRS balloon tracker that holds off while waiting for the channel 
to be clear will likely never get a packet out at altitude.  Unless 
you're on an alternate frequency, you just have to keep the power down, 
use a reasonable beacon rate, and limit the path.
