Every Wawa in Virignia that I've monitored uses 154.6000 [ d413]. I would check this frequency, as well as other dot/star/itinerant frequencies if that's not it.
Thats what I was thinking Bruce! haha...I live within about 2 miles from a WaWa dont hear anything at all. I guess they dont have a very strong output. Probably have to be in the parking lot.
