KD2DO bringing up a new gateway (I hope)

I am bringing up a RMS gateway for the Rochester NY area. It will eventually be put on the top of the County Public Health building downtown. I am running a prototype at my house using a Yaesu FT-2980 into a 15 ft dual band vertical sitting on a fence post. The frequency is 145.03.
I can do Packet and VARA-FM.
Can anyone tell me why I am only listed in the Packet category and not also in the VARA-FM category?
Can anyone tell me why my 6 character grid square is turned into a 10 character location that is about 7 miles off?

Could I run two instances of RMS Packet on the same computer and connect the other one to a UHF radio?
