Great work! Submit this to the database using the submission feature. This is what I have been doing as I've been picking up and discovering things.
I also noticed Troop I right in my backyard at work (The Naugy site I believe) that is all 700mhz also has TDMA enabled, I had two LCN's show up for one frequency repeatedly. Have not seen this on any site with 800mhz.

I believe you are correct on Troop K. It seems the entry on RR database does have some missing frequencies.. 3 frequencies for a site is a little low. Add them in!
As for Site 37 and Site 38, others have reported seeing those as well. There was confusion as to where they were, someone though. Site 37 being Linked to B seems to confirms it's a Stand Alone site in Troop B area possibly Sharon or Waramaug area. I don't see them on A, I, or L sites I can pick up from home.
While I was in the Old Saybrook area last night, I have those two control frequencies in a separate list I made that only had those two sites listed. I copied a frequency that someone else reported as the control frequency for Site 37 before of 859.937500MHz and did get hits on that in the area around Brandford, and again stronger near Westbrook area at -90db. However the frequency I was looking at appeared to be a voice/data channel, NOT a control channel. So this fits in line with what I was seeing. I believe you have the correct control frequency now. (Whatever was reported before was wrong, or changed). So I believe this is SOMEWHERE in the South East part of the state. Not sure where still exactly other than it can be hit from Westbrook most likely, and it's link to Troop F seems to confirm that.
Meh. Discones are a bit of an eye sore. I've been unable to mount anything outside as well, and resort to my indoor window mounted antennas.
When you use the Full Database version, you're going to get worse results. Using just the Troop L control channel on your SDS100, your scanner just scans the one frequency, listens to the control channel which tells it if any other frequencies are in use at the site and will have your scanner tune to those if they are in the talkgroups you want. To cycle through it once takes 0.25 to 0.5 seconds, then it will loop around your scan list.
When you use the Full database, it's scanning EVERY frequency for EVERY site. Not just the single control channels. For a single site, thats 4 to 7 frequencies it's checking, when your SDS100 only needs the control channel since it has "follow" features for P25 control channels (The HP II does not I found out....). It takes a while for it to scan those frequencies, determine nothing is there, and move on to the next frequency to scan. Then.. on top of that.. if you're using all sites, you're repeating that 13 times over. So effectively instead of scanning one frequency, you are scanning 67 frequencies. It will take your scanner 3-5 seconds at BEST, most likely closer to 10 seconds or more, to loop around through all 67 frequencies. That increases the chance of you missing a transmission on the one frequency you really only need to be monitoring, as the majority of transmissions sometimes are just a couple seconds long "Roger" "Car XYZ Troop Y" etc...
So for CSERN monitoring, with a SDS100 you really only need the Control Channels, and with 13+ sites try to limit the sites you scan to just the ones in range that you want. I have one Favorite List with *just* the CC's of all the sites for when I'm traveling, and ones for each site specifically with just the CC's for that site enabled, and just those TalkGroups enabled as well, along with some neighboring Talk Groups sometimes. It's VERY hard to get zones setup if you are roaming.. static positions or locatiosn are much easier to setup..
CSERN UPDATE ON MISSING SITES (Consolidated from this post)
Site 37 Control Frequency of 853.050000 is in Westbrook area maybe, somewhere in South East part of state linked to at least Troop F site.
Site 38 Control Frequency of 774.518750 is in Troop B area somewhere, possibly Warramaug or Sharon, and linked to at least Troop B site (*Not* L however so it must be pretty far North, leaning towards Sharon).
Troop K Site 30 has a few more frequencies than the RR database has.
