AMR in Colorado Springs dispatches for several different areas (Colorado Springs, Pueblo, Canon City, Missoula, etc), however, AMR Denver is dispatched from Denver. It's possible that you have freqs for the Colorado Springs system in your scanner.
I tried programming the above for LTR and when entering 939.75 my 396t read ' out of range'. any suggestion. The others went in okay , cool, one tg is 0-07-001
Valid LTR Standard systems can only have channels numbered 01 through 20. 28 is not valid. If you look at the system linked to in this thread you will see the system is listed as LTR Passport which is not trackable by any current scanner.
