There is nothing odd about that license. 10 frequencies. If it truly is an LTR system using frequencies on those licenses, then it'll have 1 to 10 active frequencies with LCNs assigned to them between 1 and 20.
The simplest thing to do is program all 10 frequencies into a bank conventionally. scan it. See if you hear activity that sounds like US Steel activity. At that point you'll know the system is active.
There is a document in the wiki that descriptions widely used procedures for determining LCN order. Basically what you seem to be asking is for somebody else to do the legwork. My guess is that somebody else would have already done the legwork if they weere so inclined. that leaves you with doing the legwork (determining proper LCN order so that you can scan the system in trunked mode and make use of the talkgroups, locking them out, enabling them, whatever).
You should read this link for starters:
Mapping an LTR System - The RadioReference Wiki
If it were me, and if I were using a Uniden like you are, I'd do this:
1. Program all 10 frequencies into a bank conventionally
2. Make note of every frequency that appears to be an active frequency in use by US Steel
3. Create a new LTR system
- program the most active frequency that you discovered from scanning conventionally into ALL 20 channels of the LTR system
- scan the system as an LTR system
When you hear a transmission while scanning that trunked system, you'll see on the display something like this:
0-HH-GG or 1-HH-GGG ( 0-01-30 or 1-15-190)
- where HH is the home repeater
- where GGG is the talkgroup
Typically, but not always, the home repeater (HH) will be the LCN associated with the frequency it stopped on.
So, if while scanning, it stopped on 464.35 and displayed 0-05-100, then:
HH = 05 (which likely, but not always means that the LCN is 05)
So then you know 464.35 is LCN5.
Go back into that trunked system and replace LCNs 1-4 and 6-10 with the second most active frequency that you had noted in your conventional search. Scan the system in trunked fashion.
When a transmission is occurring on that second most-active frequency that you entered in, make note of the HH again. If that HH shows 09, then LCN9 is associated with that second most-active frequency.
Edit the trunked system and change 1 through 4, 6 through 8, and 10 to the third most-active frequency.
Repeat add nauseum.
It's actually pretty fun. I have seen people [perhaps you, perhaps someone else] wanting the information regarding this trunkeed system in the past. Instead of waiting for somebody to post it, it is better for you to figure it out yourself. If it's a busy system, you can figure out a lot about it very quickly.
A few things to keep in mind:
1. If the system isn't very active, it coudl take significantly longer to figure out
2. Just because 10 frequencies are assigned to the license, don't be surprised if not all of 10 of them are in use. Even if all 10 are actively a part of the trunked system, some of them may only be used when the home repeater for a certain talkgroup is in use, in which.
3. HH referenced above is most often indicative of the LCN associated with that frequency, but not always.
