I can now confirm that this system is in use. I heard DMPD put out a call regarding a shooting on the north side on the I-Call channels (VCALL10/UCALL40/8CALL90). LINC was also used, but the call went out on I-Call first.
Thanks for the update. I added all the VHF/UHF Tac frequencies to the Common/Shared page. From reading about the narrow banding, it sounds LE is being encouraged to program theses frequencies into their radios during the NB process.
