Charlottesville/Albemarle 800 system

Hi all, first time poster here. I'm a firefighter in Albemarle County, recently frustrated with the lack of a quality feed for our County on broadcastify has led me here.



Over the course of the last week, I setup a new feed using a BCD886XT -- Albemarle County Fire and Rescue Departments. My goal for this feed was to only broadcast 4 channels from our 800 trunked system. (ACFR Disp, ACFR Resp(Priority), ACFR ATAC3, ACFR ATAC4. I was successful in this endeavor, as far as setting up the hardware and the feed goes. I get a good quality stream and sound from it most of the time. Our 800 system is here: Simulcast Site Details (Charlottesville / Albemarle)



During my research, I'm led to believe that I'm experiencing a common issue with digital/choppy audio caused by the Simulcast nature of the system. The feed scanner is located at 38.005659, -78.377426. At this moment, it's using the retractable antenna that came with the scanner, but I have the resources to mount a mast antenna on our building. If my research is correct, then the closest tower for this system is 37.98233, -78.48236 (Carter's Moutain). With several others in the area.. Peter's Mtn, Liberty Hill, Fan Mtn, Bucks.



How can I determine exactly which towers this system is simulcasting from so I can determine the best type of antenna to purchase in an effort to attenuate the offending signals?



Random note: I actually live in the town of Culpeper, and when I set the scanner up initially and programmed it, everything on the 800 system came in crystal clear all the way from albemarle. I'm assuming the signal I was receiving was a lone signal being broadcast from Peter's Mountain.



Thanks for all the great info here and I hope you guys can open my eyes to the world of radio frequencies, I'm a total noob at this stuff, but once I dig into to something, it really becomes a hobby of mine.



Looking forward to chatting here!
