The Radio Information Board

i'm planning on putting up a new ham repeater, I've pretty well decided on the VXR-7000 and the repeater frequency in the 443.900mHz.
so, does anyone know which one to get

VXR-7000UD 450-480MHz
VXR-7000UA 400-430MHz

If you are planning on getting it from http://www.rfwiz.com/VXR-7000_Front_InfoDat.htm
give them a call and ask. He will be able to tell you. He is a HAM operator and has been in the Vertex business for years.
