Looking at other on-line resources, I saw a discrepency with a frequency.
On the database here, they list 851.0125 , however I have seen 852.0125 listed elsewhere. Try changing that freq. Also no control channel is listed here for Baldwinsville. :? Are you catching it ?
Go to the NF2G Scannist Pages - Trunking Page at http://nf2g.com/scannist/smr_research.html - scroll to the bottom of the page and click on EDACS, then select the system (Onondaga County). All of the details are there.
Were you looking for frequencies licensed to the county or to the radio shop that operates the system?
If anything is missing from my listings, it is a new channel that wasn't on the air before. There must be a license for it somewhere. You might also try searching with your scanner for an EDACS control channel that isn't accounted for.
