While your BC245 will not receive Grand Prairie, there are a number of other possibilities for listening, in addition to Dallas PD & Fire. There's still quite a large number of conventional frequency usage in
Dallas County.
Tarrant,
Johnson, &
Ellis Counties also have a number of users that are not trunked. As for trunked radio systems, Grand Prairie, Mansfield, and a couple of small federal systems are the only ones in this area that are digital, as is Tx DPS (not on a trunked system, but digital on conventional frequencies). You could still put that 245 to use with multiple conventional frequencies, and neighboring trunked systems such as
Arlington,
Irving,
Fort Worth, and the
NE Tarrant County systems. Other systems within your scanners capability include the
Carrollton and
Mesquite trunked radio systems.
