==MSP and County Trunks==
MSP has been allocated portables (and in some cases mobile units) to communicate with the trunk system in the area they serve.
Typically these will be used unless the unit is out of range of the trunk or in a bad coverage zone, in which case they will
revert to their standard loband frequency (or sometimes Nextel). Traffic is often echoed from loband.

; Notes
* Talkgroups in {{color|blue|blue}} are used on a digital system, and require a [[:Category:Digital Scanners|digital trunktracker]] to copy
