Hamilton Co. EDACS Control Channel Change
Hey there, had a BCT15 several years ago but recently jumped back in when I saw how cheap and capable the rtl-sdr dongles were. Following and listening to EDACS and P25 etc systems for $30 in great sounding quality ain't bad! Even if you have to be a half wizard to get it working.
Anyway, I know hamilton co is in the middle of moving to Indianapolis public safeties P25 system (as their own Site 3), which I've monitored a bit but there's next to zero traffic on site three so just monitoring the EDACS system for now.
The Radioreference page for this system lists the only EDACS site as Site 1, with control LCN's of 5 and 10. Shown here - Hamilton County Public Safety Trunking System, Noblesville, Indiana - Scanner Frequencies
However there's no such system to be found. The control channel is now actually LCN 8, and when you listen to that channel with a trunk information program it shows the EDACS data is clearly identifying itself as Site 2. No site 1 to be found, and no other control frequencies around. It's obviously the Hamilton Co edacs system and I'm monitoring it great, however it seems they have changed the site number delegation in the EDACS system from Site 1 to Site 2, and the control channel is now LCN 8 at 853.075mhz. I've been monitoring it for a couple weeks now, and it's been LCN 8 as control this whole time, hasn't changed.
So I guess my question is, should the radioreference DB page be updated to reflect this? This drove me crazy for a couple days when I received my SDR dongles, I tuned to both specified control frequencies listed on the DB page and got nothing but occasional voice, so I gave up thinking they were in between edacs and p25 and there was no longer a working edacs control channel. However a couple days later browsing through the spectrum I saw plain as day an EDACS control channel in the waterfall view and tuned to it and voila, Unitrunker pops up the hamilton county system, although it's identifying itself as site 2, not site 1 now. Also worth noting LCN's 1, 3, 6, 7, and 11 don't seem to be used now. At least I haven't gotten any hits on them in two weeks while tracking the system. Perhaps those frequencies are now being used for the P25 Site 3 Hamilton Co testing? (edit: after monitoring the P25 Site 3 trunk (hamilton co) these 5 frequencies are definitely being used as P25 LCN's for testing well as a sixth new frequency, 859.81250, so that would explain why they're no longer being used as LCN's on the EDACS system. Perhaps these LCN's should be removed from the edacs db page as well?)
I guess I'm just wondering if someone should update the DB page to reflect the new control channel and site number to help other poor confused souls out Even if it will only help for the last month or so before the edacs system is gone
You can see in a screenshot here the system clearly working on LCN 8 as control - http://i.imgur.com/IHsiv66.png
Thanks in advance for any help, this forum has been a savior. For anyone on the edge about purchasing these cheap SDR dongles, I highly recommend it as I'm tracking and decoding P25 voice (indy public safety) with a nice Unitrunker GUI for the price of a pizza
