[AMSAT-BB] Portable Sat Tracker for Field Day

I'm running into a brick wall with getting the Autonomous Satellite Tracker, homebrewed from WB0OEW's design, to work with an iPhone hotspot for Field Day. Does anyone know of a portable tracker that would handle the Elk that I plan to use on FD? A homebrew project is OK, but the SatNOGS thing is out due to time limitations. Off the shelf is preferable. BTW, I'll be running SatPC32 on a laptop to control the IC9700, so it would be ideal if the portable tracker worked with the program's rotor control. I can dream, can't I?
