For anyone who might need it, here is a link to my documentation for using the Vertex VXR-7000 radios with either a URI or a modified USB fob such as the StarTech. If anyone has any corrections or other helpful tips, please contact me directly and I will be happy to edit the page. http://aplaceonthe.net/blog/connecting-the-vertex-vxr-7000-to-allstar-app_rp... 73, Thor N7JCT
