Thanks for the input everyone.

Cool, we will probably go with something more along those lines then.

We will usually always be running the D700 in low power, which I believe 
is 10W. Our shopping list does include fiberglass mast sections, and we 
already have a few different antenna options for the top of the mast.

We already have a couple of D700 units and getting more radios is like 
pulling teeth. While they may be overkill eventually the digi will be 
located in an Argo (http://argoatv.com/products/product.asp?MID=10) and 
have the ability to see the teams on their GPS. Most of the time I get 
stuck purchasing "parts" like that myself, proving that it works, then 
they *may* end up making a purchase.

I'm currently thinking about the USB micro TNC from elcom with one of 
our Bendix King HTs. My personal tracker right now consists of a BK and 
OpenTracker, which was much cheaper and IMO works better than the D7As 
the unit has. The only downside is that I don't get to see other teams 
on my GPS, which is a very nice feature.

Thanks for the input,
Josh
