Why cant I hear regular radio stations on my scanner?

Post by Gardner May » Mon, 05 Jul 1999 04:00:00

 I was wondering when I first got my scanner why can't I hear regular Radio
stations on a scanner, For example, a station named V-103 which is on 103.3
MHZ on a stereo but on the scanner the same 103.3MHZ is hardly nothing? .
I know that expensive base scanners can pick them up. they call them the
"extended frequencys"(see your radio shack catalog).  I never could figure
out whats the diffrence, so any thoughts would be appreciated.

Radio stations transmit in Wide Band FM (WFM), most scanners only get Narrow
Band FM (NFM) which is the mode that most FM transmitters and radios use.  Only
the more expensive scanners will allow you to switch to WFM.

The actual parts required to receive WFM aren't very expensive - check
out a cheap consumer FM receiver sometime.  But they are different from
what you would use for narrow FM, so a receiver than handles both needs
to duplicate some parts, and this necessarily adds some cost.

The actual cost of adding FM to a specific receiver isn't much, but
it's enough to ensure that the feature will be missing from the lowest-
cost scanners.  It becomes a feature, like AM reception and wider frequency
coverage, that's available in more expensive scanners.  But those are sold
in smaller numbers, so the cost difference between a low-end and high-end
scanner is far larger than the difference in the cost of the parts - because
of the smaller volume for the higher-end gear.

Anyone know why its so expensive to be able to get WFM in a scanner?
Seems like it would be real cheap.
