Where im at,even near the Virginia border,on the quad SDR trunk set up,20+ foot multi antenna set up,2 preamps in line,i dont get any cc signals from the nearest vsp stars sites..though this evening i looked up the fcc licenses for VA sp and found 5 or 6 freqs not in the listed Stars cc database,so im gonna try them in the next couple days..earlier today i was on the parkway and got No CC activity on the listed rr data i had programmed in for Grayson,Carroll,Patrick,Smyth county sites..i was like jeese,this area is a radio rf dead zone..i dont have any of the listed encrypted tg's programmed in,wouldnt matter,id still get a rf signature from the continual control channel flow and the listed freqs arent showing on the spectrum..anyway,ill try the fcc licensed freqs i found this evening and see if anything shows..i also put the NAC at F7E for one system set up,but once again,there isnt a signal being shown for the listed cc freqs..then again,it may be obstructive barriers( mountains) as a cause...Anyway,a curiosity..back before VA went to trunking,it was easy to hear Div 4 Wytheville in Winston Salem on 159.00mhz( or whatever it was back then)...Any thoughts,opinions welcome
