Site neighbors/peers/adjacents should help identify the site if someone can put a control channel analyzer software (DSD+, UT, PRO96COM, etc) on it.
Something I discovered about site NACs on AFRRCS a while back which may be useful to people who can make use of the info - example, people with SDS scanners (which can set and use the NAC of a site)...
If you (know and) take the "AFRRCS Site ID" (not necessarily the same as the P25 site ID, for example St Albert is 05A-52, but is AFRRCS site 0212), and add 780 decimal, the result will be the NAC in decimal - convert to hex to get the hex NAC. So St Albert is 212, add 780 you get 992, convert to hex you get 3E0.
So 3CC is AFRRCS site 0192. This has worked for me for every 700 site so far. The VHF sites (VDOC and multichannel sites, not MTRs) seem to be similar, add 300 instead of 780, but do the dec to hex calculation just the same.
So site 05A-032 is confirmed as Edmonton International Airport. I will submit the 12 LCN's I've found to the database.
