STARS and Pulaski Co.

I travel to Pulaski Co. two or three times a year. For reasons I do not understand STARS seems to be a dead spot. I have all of what appear to be the appropriate tower information programmed into my Pro 106. I am really only concerned about VSP and VDGIF. (local frequencies do not seem to be an issue) I am able to pick up some faint traffic on the legacy frequencies for the Salem and Wytheville divisions. It seems to reason that this should not be an issue given Interstate 81 travels through the county and it is only a slight distance away from the Division 6 (Salem) headquarters. Can someone tell me what I am doing or programming incorrectly? If anyone wants to share a Win500 file I would be grateful for that also.
