Yes.. very nice.. Is this somethin that is going to be shared as far as opensource for building it?? I recognize the atmega, just not the other components.. Must have one..:)
Dreamglider -- As for antenna tracking, it would be easy to implement code that spits out az/el data in easycomm or yaesu-compatible format for a trackbox to consume. The 12C line could control a tracking system like the AA2TX one directly, too.
But truthfully, my goal in this miniaturization is to simplify portable operation with a HT or FT-817 radio and a small antenna. Up 'til now, it was hard to have full doppler tuning in these circumstances.
Dreamglider -- Most of my work is still on breadboard, and in that case, you're best just following my pinouts described at the top of the code for the project published at the website described in my post to hgravina.
You'll find at my blog -- reached by googling 've9qrp and blogspot' -- that I've made some eagle files for a small dongle based on the arduino mini. These, too, are available in the svn repository, under the 'Hardware' directory.
The code is open-source. Unfortunately, I get an error message when I try to post a URL here, so search for 'googlecode' and 'qrptracker', and you should get right to it.
You might run out of code space with two software serial instances. You might consider using the Sanguino / atmega644p, which is the target hardware for my continued work.

does this provide antenna tracking ?
how about schematics please :)

Will you share the code ? I am tinking in use arduino with 2 simple recivers ( ft-817 ) to simulate one ft-847!
