The 463.575 repeater isn't even around anymore. Life Lion EMS uses their encrypted private channel on the county TRS.That's what I thought too...all VHF and UHF public safety frequencies need to be NFM. However, Cumberland County Med Channels 1 and 6 still show as FM in the database. I just added the frequency for the ground based Life Lion unit to my portable (463.575) and that is also listed as FM. I am to assume that these are outdated and any VHF or UHF frequency should be modulated as NFM?
I do note that, when I have the Life Lion modulation set to Auto, it does show as NFM on my scanner.
