Default Is noaa weather wide or narrowband?

Hi,

I am programming some radios and noticed that the weather channel was really staticy. I noticed that the personality was wideband. Since I am converting the radios to narrowband I changed the noaa channel to narrowband and it got a little louder, but still hard to hear. I found a different frequency 162.450 and that is coming in pretty good, but I don't know if I should use narrow band or wide band. So which should I use? Is the squelch type CSQ? I have the weather personality setup to receive only.

Thanks,

The NOAA Weather Radio Broadcasts are all wide-band. They are not affected by the FCC narrow-band change for Part-90 frequencies since they are a different service. I do not expect that they will change from how they currently operate except to possibly define additional SAME codes if situations call for it.

I always wondered about this -- they are not subject to Part 90, but should have been subject to the 2005 federal narrowbanding effort. I assume they got a waiver due to the fact that all the weather radios out there are wideband, and that there are no plans to narrowband.

4.3.7 2.
As an exception, NOAA Weather Radio operations on channels in the frequency range 162.3625-162.5875 MHz may continue to operate with necessary bandwidths equal to 16 kHz.

You sure its the right broadcast for your area? I pick up NOAA from out of state on my pro 164

NOAA does not transmit a pl so you would set up for CSQ. They transmit (voice) with a 5 kHz deviation.

Now I really wonder,because I have vhf commercial radios that do not have WFM mode and they will receive NOAA. The same is true for several of my ham rigs.

Hmmmm.

And you wonder why there is so much confusion listening to a bunch of geeks on the scanner site.

Today's WFM is yesterday's NFM. Used to be that WFM was +- 15 Khz and NFM was +-5 Khz. Now 5 Khz is considered WFM.

Your radio will pick up NFM even if it is programed for WFM and vice-versa. About the only difference is the amount of audio gain programed in to keep the audio level about the same. They don't change the IF bandwidth unless your radio has about 4 different IF filters (10 Khz - NFM; 15 KHz - WFM; 100 Khz - Commerical FM, 12 Khz - AM).

That is the map I used to chose the the new frequency. I am switching from 162.55 at 1000 watts to 162.45 at 300 watts which is closer to the town. It is still a little staticy but is better than the original frequency.

Thank you all for the information. I am programming CP200, HT1250, cm300, and M1225 radios. I haven't seen any place for a same code in the Motorola programming software. I will leave the setting as wideband.

Thanks,
