Hi Dave, and the group.  The tones were there in the background.  I
monitored a short transmition about what sounded like a delivery, but I
also heard that this system and other MPT licenses are really hard to
trace any contact information, but I will be going to the FCC homepage to
try and see what I can find here.  I'm still curious about what others are
hearing from the 220-222 MHz band.  The modulation seems like a step back
in technology to me.  I had always been under the impression that this
kind of a system would be digital, and here I find it to be ACSSB.
