This will affect many of us down the road and is something
we all need to be preparing for.
These rules, as they stand now apply to all non-public
safety LMRs under 512Mhz.
In short, any new repeaters must be narrow band
by 1/1/2011 or their license application will be denied.
So after that date, applications for new systems must
reflect the new narrow band or they will be rejected.
By 1/1/2013 all radios and repeaters sytems under 512Mhz must be at the 12.5 narrow band or they could loose the right to use them from the FCC.
With the number of radio system we use this will not be a
cheap fix. We are setting funds aside now for this and looking
into what can be done to convert our current systems to the
new bandwidth requirements.
In some areas the counties are looking into helping the
spotters cover some if not all of this cost.
This could silence many spotter groups if they are not prepared.
I am very interested in hearing what other spotter groups
are planning to do to meet this new requirement.
Deadlines
To phase in the migration deadline of January 1, 2013, the FCC has established interim deadlines.
The first important deadline is January 1, 2011, after which:
The FCC will not grant applications for new voice operations or applications to expand the authorized contour of existing stations that use 25 kHz channels. Only narrowband authorizations will be granted.
The FCC will prohibit manufacture or importation of new equipment that operates on 25 kHz channels. This will reduce the availability of new equipment for legacy radio systems and will affect how agencies maintain and upgrade older systems.
Private land mobile radio (LMR) systems—including municipal government and State and local public safety systems—use blocks of radio spectrum called channels. (See Radio Spectrum9766.) Historically, LMR systems have used 25 kHz-wide channels. In December 2004, the Federal Communications Commission mandated that all private LMR users operating below 512 MHz move to 12.5 kHz narrowband voice channels and highly efficient data channel operations by January 1, 2013.
