I have two scanners a old Pro 100 from Radio shack and a VX-150. My question is with the narrow band coming would it be best to upgrade or keep my scanners? From the posts the effective date doesn't necessarily mean that it will change that date, however I understand that the mandate will go into effect this Wed. That said,what options do I have to play with?

What is your malfunction?
There are some radios that has the capabilities for upgrades from the standard AAR bands to narrow bands, I have a portable Motorola than could be changed to narrow band with the proper software.

I would think those radios should still be good. If they were to go digital then it would mean a new radio. If i am correct it is just a bandwith change so most analog scanners should work.
I also could be totally wrong too.:D

A post on TO told of this "Changing from wide band to narrow band means if the basic frequency remains the same the audio level will be less. Deviation in FM is the amplitude of the audio signal on voice networks. The higher the frequency of deviation means the basic frequency varies that much. However if they change the frequency then you will need to change the frequency but the audio level will still be reduced due to the decrease in deviation(audio level). "
So what i think he is saying is that it will be the same but the imput will be less, but not by much. Im seeing diffrent dates for switchovers some have been done, so with that said Im not sure ALL of the UP system will switch tonight.

Well the changeover came and went for the UP. I'm montering different UP channels via the web, so far no real change in audio is being noticed. Last night must have been after midnight I also turned on my scanner, I thought I heard train get a track warrent via Tara sub or the Jewell but fell back asleep before I could ajust and hear the end of it, so A the change didnt happen around here B the change had a minimal effect.

The BNSF has switched to narrow band in my area of SE Texas on the radio towers only. One big difference is there is no bleed over on adjacent channels as there was before from transmissions made from the radio tower.
