Curious to know what current scanners will program for the newer 12.5 ( Narrow band ) freqs. ?

Currently we have no digital radios in our 3 counties, so just need top find a 300 channel or more scanner that will do narrow band.

Thanks
Alex

Hi Alex,

You have to be careful when talking about "Narrow Band".  For years scanners have had two types of scanning for FM signals.  The lone designation "FM" often was used to denote "wide band scanning" like your local good-time FM music stations (88-108 MHz).  Public Safety and business have operated in the "narrow FM" spectrum (sometimes called NFM) since the late 1950's (150-174 MHz) or so.  

Now, to further complicate things, the FCC has mandated that present land mobile licensees operating in the narrow FM channels must relicense and change equipment to operate on what is ALSO being called "Narrow Band" channels by January 1, 2013.  Think Narrow Band I (1950's) and Narrow Band II (2013).  This version of narrow banding of the spectrum will take channels from 25 KHz spacing down to 12.5 KHz spacing, creating more useable channel assignments.

So, when looking for a scanner, make sure that you confirm that a specific model is capable of the new 12.5 kHz spacing, regardless of what the catalog or sales rep might call it.
 
The folks at 1-800-SCANNER offer to answer those model specific questions for you (I have no affiliation with them).  Also, do some research on the internet.

Good luck,

Terry, WØFM
