Additional New LMR Frequencies Found

Last weekend (10/14/06) I noted that the following new frequencies were being used:
140.250 P25, base side only heard
141.3125 (NFM), possible repeater callsign monitored was "SHADOW"
149.6875 P25, brief transmissions, couldn't get specific info.

Since the 104 FW Barnes ANGB (Westfield) had its' UTA during this period, I'm assuming these frequencies are assigned to that base rather than 439 AW Westover JARB (Chicopee).
