In theory...if you have a receiver that accepts a signal 25kHz wide,
and the transmitters<br>
are sending a signal that's 6.25KHz wide, you'd be listening to four
adjacent channels at once.<br>
And if only one of those channels were active it could be very quiet or
distorted.<br>
Truth is I've been listening to narrow signals with a wide receiver for
years (2 to one, not<br>
4 to one) with no noticeable difference as long as the adjacent
channels weren't busy as well.<br>

<div>This question is for the radio experts out there. I read in <em>Railway
</em>Age magazine where the FCC is requiring railroads and other
commercial communications shift to narrow-band radios (shift from 25
kHz to 12.5 kHz) by 2013, with the possibility that the FCC soon will
require a shift to "narrow-narrowband" (6.25kHz), or all-digital radios.</div>

<div>What effect will these changes have the decade-or-so old
scanners that some of us have?</div>
