Narrowband Scanner List?

[Rt169Radio]

Hi all,

I was wondering if there is any list on RadioReference that shows all the scanners that can handle the new narrowbanding changes both on VHF and UHF?

For example I have a Uniden BCT15 that can handle the VHF change,but am not sure if it can handle the UHF change? I also heard that you could put in the closest freq nearest to the freq that you want to listen and you would still be able to listen to it?

I think if you look in the wiki for the specific brand of scanner you can find witch ones can and cannot.

Per dispatcher812, look at the steps to see if they show 6.25, 7.5 (typical in Public Safety bands)

I also heard that you could put in the closest freq nearest to the freq that you want to listen and you would still be able to listen to it?

That is generally true. If the station is far away, you may not get them very well, but that in not typical.

The answer would depend on what is meant by "handle"? Do you mean having the correct steps for setting the frequency, having the correct audio compensation for the narrower deviation of the signal, or having a narrow IF filter to reduce adjacent channel interference?

Well it says that the Uniden BCT15 has the 6.25 and the 7.5 step in it.

But the thing is I don't think it will be able to handle the new way the UHF channels will be changed to.For example when I put in a regular UHF freq like 453.30000 MHz it was able to accept that.But when I put in the new way that freq will be changed to like 453.30625 MHz the scanner will put in like 453.3062 MHz . Would I have to change the step to 6.25 instead of having it on auto? Shouldn't the auto step function fix that?

On most Unidens, you have to change the "auto" step to NB.
Easier to Read BCT15-X Scanner Manual

Edit: Sorry. Read your post too quickly. Looks like your auto step has the changes for NB, UPman is correct as always.

The scanner only displays to 4 digits to the right of the decimal point. Whether it actually uses that 5th digit is moot, as a difference of 50 Hz would have absolutely no affect on receivability.

In general, most (if not all) trunked scanners are already going to handle narrowband. AFAIK, at this time the only non-trunked scanner that is set up for narrowband is the BC125AT. (There are some communications receivers that certainly can, too, but I really categorize those as a slightly different class of animal.)

Thanks for the info.

rt you say you have tryed to enter a frequency of 453.30625, a) this is not a legal working frequency for either the scanner or a user, B) the correct frequency should be 453.3625, 3650, or 3675.

No scanner will let you enter a 5 digit behind the decimble, have to use only 4

I was using the freqs as shown in the narrowbanding topic in the RR wiki.
