I think I've managed to plot 21 or 22 (depending on reuse of existing sites) of the tower sites for the new 22-site system in my ongoing (and seemingly never-ending) project to map all the public safety systems in Maryland. During this process, it's interesting (but not surprising ) to find errors and missing data. It's probably due to data entry and paperwork slip ups, but I did run across an operational site in AA County that was unknown (to me at least.) Way back when, there was a tower site in Crofton that is recorded on one of the FCC licenses for the system. That site was cancelled and never built at the coordinates provided. A few weeks ago, I was browsing the FCC antenna database for intel on the new P25 system, and came across a 2018 approval for a tower site in Gambrills. I assumed this was a new site for the P25 system, but it described the tower as constructed in 2000's. It appears that the Gambrills site location replaced the location in Crofton, but the station licenses don't reflect its existence.
