For years I contemplated owing my RTK base but because my farm is spread out over 30 miles and I would need several and/or a repeater I decided I didn't want to deal with it.  Well the urge to tinker hasn't left and this week I ordered some Sparkfun/u-blox hardware to start playing with it.  Currently my RTK corrections are satellite delivered (Centerpoint RTX) for three systems..  I run four systems and unfortunately they are all different.....and old FMX with a 900 mhz radio, Pro 700/372 with no 900 mhz radio, Trimble TMX 2050 that has a dual GPS receiver and I think a 900 mhz radio, and a Pro 1200 currently receiving from the dealers 900 mhz network.

I'm confident I can setup this base so that I can deliver corrections using NTRIP over cellular and use a Back40Precision device and iPads but I'm also curious about using the 900 mhz radio that came with it for making a portable base for dirt work.  How would the Trimble radio connect to this device?
