Title: New Narrow Band Requirement Question?
Post by: KF6OCI on December 02, 2012, 03:13:23 PM
Will amateur radios still be able to listen to the narrow bands?

Will it affect anything?

  Thanks,

Using a wide receiver to listen to narrow band transmissions will result in lower audio output and you may hear interferrence from stations on an adjacent channel.

What radio will you be using? Some radios can be programmed for narrowband analog reception.

You will be able to listen at lower volume, provided the public service or commercial entity doesn't move to a "splinter" frequency, such as 155.5675.

Some radios have a "wide / narrow" setting. This will allow you to hear the ones on non-splinter freqs at the higher volume levels.

It won't affect anything if you're listening to ham traffic.  Narrowbanding doesn't target ham radio signals, at least not yet--and not ever, if we're lucky. 

If you use your radio to monitor out of band signals, though, you just notice reduced volume--as someone already pointed out.

At some point there will be a push in the more crowded areas to go narrow to open up more repeater pairs.  A problem which could be solved in many areas if the coordinators would do their jobs and de-coordinate non-existent repeaters.

MORE repeaters with antennas on the back fence?  We don't use the ones we have.

Not to prolong the agony (I'm going to do it anyway!   ;D ) but I don't think you'll see that.  The two meter repeater frequencies have been full in many areas for many years now, and there isn't--with a few exceptions--any sort of move to change to narrowbanding.  It's simply seen as not necessary.  Add to that the amount of equipment that would have to be replaced and/or junked by ham operators, and you'll see that any sort of a move to do that on a national scale would come up against some strong opposition.  It has been done in some small areas, but I don't think you'll see it being widely done for quite some time--if ever.
