narrowband freqs

[snorkle]

Has the fcc posted the narrowband freqs that will be going ineffect on 1/1/13,?. If so where does one find them.?

Nothing New for Frequencies.

The real just requires agencies to convert the radios on [many] the existing channels to Narrbowband radios.

ie: An agency on 154.2950 would remain on 154.2950

Folks are making this much harder than it really is. If a current user's frequency is 155.0000 using a wide FM channel, their "new" narrow band frequency will be 155.0000, but their channel width will be about half of what it was prior to being narrow banded. Simple enough.

Now once everyone associated has moved from wide band FM to narrow band FM, the FCC will start assigning new users the frequencies inbetween the old wide band channels so there could be about twice as many channels available in that frequency range.

Sorry to say, but that may be the FCC's idea about additional channels. All the coordinators that I know of got together and decided that there were not going to be any additional VHF assignments. They stated that even with the narrow banding, it's still too close and there was going to be overlap, so they aren't going to coordinate any. I guess they are waiting for the 6.25 mandate. Maybe around 2020.
BTW you won't find any documentation to that effect just yet, this was the outcome of a meeting they all had back in July. The reason I know this is I started putting applications for the 12.5 channels and they were sent back. The phone call that followed gave the response above.

I'll set aside my comments on the rest of the replies.

snorkle,

The Federal Communications Commission hasn't...but the Government Printing Office has. Visit
http://www.gpo.gov/fdsys/pkg/CFR-2009-title47-vol5/pdf/CFR-2009-title47-vol5-part90.pdf and scroll down to page 22 of 292 (or the original document's page 256, depending on what method you prefer) to find the start of what you're looking for. By the way, these frequencies are valid right now. If licensed, one needn't wait until 2013 to start using them. The only thing happening on 010113 is that after that date, the use of the wide band mode on frequencies between 150 MHz and 512 MHz will no longer be authorized - except in certain very, very limited cases. Print the PDF and read it at your leisure to get an idea of what's what.

I havn't read what your talking about, but try licensing on VHF in the NYC Metro area and you will be denied. I have no less than 20 applications returned for reason of being too close to adjacent incumbents.

i think that just depends on area and frequency congestion. around here you can get VHF freqs all day long, though for the last 5-6 years ONLY new narrowband freqs have been available in public safety bands. one local FD found out the hard way when they tried to move an (unknown to them) expired license. they could not get the old freq back and had to go to a narrow band channel a few hundred khz away from the original. during the time the license was expired IMSA had given out 12.5 channels on either side of their original freq. that was in 2003 or 2004!

then again, my entire county has fewer pops than probably 5-6 blocks of NYC!
