Greetings, I am near the Loon Mountain ski area in Lincoln, NH and am hearing several control channels come across the scanner which sounds like Motorola. I have tried to search RadioReference but I find no such system listed. I have entered a trunk system into my Uniden SDS100 and tried Motorola and P25 Trunk to no avail. MotoTRBO wants an Input LCN which I do not know. How do you set up an unknown trunking system if you do not know what system they are on? Is there a way of mapping it out?

Perhaps if you check the FCC database you'll find something or share the freq here maybe someone can help.

What Frequencies ?

The VHF/UHF band today has been wide open, folks reporting from Boston hearing Nova Scotia, Maine and New Hampshire better than ever.

The systems I have heard sound like the attachments (WAV files). I have logged the following frequencies:
451.7875
452.4375
461.2000
451.2375

When scanning, they don't come up with anything on the display. Saw one ctcss. So I am not sure what I am hearing. It sounds similar to a motorola Type II control channel.

That sounds like a DMR control channel to me. Per your frequencies I found a match here:

He might be confusing "analog" versus "digital" and "conventional" versus "trunked." That seems to happen fairly often.

All the licenses are "IG" which is conventional.

can you elaborate what flavor of trunking they are using then ?
CON+, Cap+ ??
