So a couple of disclaimers:
FCC license info is not always correct. In an ideal world, it would be, but it's not uncommon for the radio shop to just license for a bunch of different emissions but only use one (or none) of them. Wouldn't be the first time, wouldn't be the last.
I have some 800MHz conventional stuff where I have the repeater licensed for analog, P25 and NXDN. I'm currently running analog only on the repeater and analog and NXDN on the mobile side.
So, here's what I can add/confirm from looking at the FCC license for these. May not be 100% accurate, and you may find something different in the field, but it's what I can offer based on a lot of years of looking at FCC licneses:
License shows both narrow and very narrow NXDN on that frequency. Shown as FB2, so a conventional repeater, likely not trunked. Repeater is located on the tank at:
592 DIAMOND ROAD
HELTONVILLE, IN
LAWRENCE County
If you are hearing data burst on this frequency, it may be a site scan beacon or GPS data from the MO's.
Like above, shows narrow and very narrow NXDN on the license. Shown as FB2, so a conventional repeater, likely not trunked. Repeater located on the tank at:
2212 HARRODSBURG RD
SPRINGVILLE, IN
LAWRENCE County
Again, if you are hearing a consistent data burst, might be site scan beacon or GPS data.
Same as above. Repeater located at:
WATER TANK BETWEEN 5TH & K STREET
BEDFORD, IN
LAWRENCE County
Looking at all three of these frequencies and their locations, it looks like they ~may~ be using a site scan function. Coverage is overlapping, but not the same. If you hear dispatch on all three frequencies at the same time, but mobiles/portables only responding on one of them at a time, that's likely the way it's set up.
The eligibility for this license is shown as:
90.20a - OPERATE COUNTYWIDE FIRE DISPATCH FOR 9 VOL.FIRE DEPTS. AND SHERIFF DEPARTMENT OPERATIONS
But, take that with a few grains of salt. This info is from me looking at an FCC license that may/may not be correct. It's probably a good place to start. The best info is going to come from you with your scanner slowly figuring this out and updating the database.
As for narrow or very narrow NXDN, they are likely only using one. While ti would be possible to run both, that would be a really odd setup. But odd doesn't mean it's wrong. Just not common.
Encryption is a real possibility and your radio won't decode that. Depending on how your scanner is set up, it might just not give you any audio at all. Your Icom will just ignore it since you don't have the keys.
Again, licensed for both narrow and very narrow NXDN.
Eligibility:
90.20a - PROVIDES FIRE PROTECTION TO THE GENERAL PUBLIC; OFFICIAL COMMS.
Location, top of the tank at:
9938 TUNNELTON ROAD
BEDFORD, IN LAWRENCE County
Number of mobile stations is the same as the three above, so may be part of the same system, just licensed separately.
License shows narrow and very narrow NXDN.
Located on the tower at:
576 KINGS RIDGE ROAD
MITCHELL, IN
LAWRENCE County
Again, the coverage of these two repeaters shows some overlap, but not the same coverage, sort of suggests a site scan might be used, or users have to select the right channel. Two sites at different ends of the county….
Mitchell FD/Water Dept. (996P2 shows NX9)
158.835 (WPUG389)
Eligibility:
90.20(A)1 - POLICE DEPARTMENT OFFICIAL COMMS.
Licensed for analog FM, as well as narrow and very narrow NXDN (not uncommon to see this)
Located on top of the tank at:
14TH AND BROOK
MITCHELL, IN
LAWRENCE County
Also located on the same tank:
155.730 on the same license. Same analog and NXDN emission types. So, likely 2 channel system, single site.
Shawswick FD (haven't heard any recent transmissions so not sure if NX4 or NX9)
158.91 (WQOG547) Not licensed for NXDN but have heard them
This call sign is for a T-mobile point to point link. I think you meant WQOG457.
Eligibility:
90.20(A) 1 - APPLICANT PROVIDES FIRE PROTECTION TO BUSINESS AND RESIDENTS WITHIN THE AREA
One repeater, licensed for analog FM and DMR. No NXDN on the license, but that doesn't mean they didn't change their mind after licensing (especially if surrounding agencies are NXDN, but could be running Kenwood NX-5000 radios that will do both NXDN and DMR.
Marion Twp. FD (996P2 shows NX9)
155.205 (WPNX555)
Eligibility:
90.20A - FIRE DEPARTMENT TACTICAL FREQ. TO PROVIDE BETTER COMMUNICATION FOR FIRE OPERATIONS AND DEPARTMENT ACTIVITIES.
Licensed for analog FM, as well as NXDN narrow and very narrow.
Location of repeater is on top of the tank at:
.2 MI SOUTYH ON HARRISON ROAD FROM BURTON CEMETERY ROAD

Bedford FD (nothing heard)
154.055 (KBY743) Note: Encrypted but I have the encryption key
Eligibility:

Licensed for Analog wide FM (not legal to use, this will get removed), analog narrow FM, as well as narrow and very narrow NXDN. Use of encryption is not shown on FCC licenses.
Single repeater located at:

LAWRENCE County
IU Bedford (nothing heard)
155.07 (KXF673) Note: Encrypted but I have the encryption key

Licensed for analog FM, as well as narrow and very narrow NXDN.
Repeater location is top of the tank at:
JCT. OF 5TH & K STREETS

LAWRENCE County
Looking at the license, they have the single repeater plus a lot of base station (FB) . Some of the base station frequencies are the UHF MED channels, and they may communicate more on those than VHF if the local ambulance companies use them more often.
Hope this helps. I appreciate all the help!
I hope that sheds a bit more light on it. The Radio Reference database is mostly done by people such as yourself. While the FCC info can be useful, the true understanding of the system will come from you and your scanner listening to this over weeks/months and figuring it out.
-Don't every put all your trust in the Radio Reference database. It's only as accurate as people have made it. Some don't always put quite the effort into it and data may not be accurate.
-FCC database is what was licensed at a snapshot in time. Shops don't always update licenses when things get changed.
