I think it was Mark VandeWettering, KF6KYI, who had a similar idea a few
months ago. Last I heard I think he was toying around with the idea of
using a Gumstix (http://www.gumstix.com/)device to be the "black box." -
There was a reason he didn't pursue it, but I forget why.
This is a easily extensible system that can be hacked up to control
doppler and handle basic radio functions. One could probably have a
simple system banged out in an afternoon. As it gets more complicated
(external display to control satellite selection, etc) it gets a touch
harder to make, but still within the realm of possibility. The good part
about Gumstix is that you don't need to get the hardware first to start
working on the software, as it's all based on Linux.
I think this idea has a lot of promise, and if I had a transceiver that
could computer control, I'd probably start designing it. :)
