[FedCom] 418.75 Active Recently

[Chris Parris]

Might not have been a trunking control channel. There apparently is a
digital test signal that they can transmit for automated coverage testing
that sounds like a P-25 control channel, but does not indicate as one on a
P-25 scanner. I heard that a lot when they were setting up the VHF IWN
system in Washington and Oregon. We heard it for days at a time on some of
the voice channels.
