    The US 216-222 MHz band is not available either. Different parts of it were auctioned to different licensees including the railroads for PTC (Positive Train Control) and aeronautical mobile isn't even allowed there.

    ND5Y SAID>The federal and non-federal users (except for marine radio) had to narrowband so that the FCC and NTIA could reduce channel spacing and cram more users into the same amount of spectrum. If any of the spectrum was vacant they would not have had to do that.

    I hope you aren't assuming that Thales's modulation will be narrow-band FM?

    It will be along the lines of the 978 UAT FSK DATA transmissions along with other data modes similar to VDL-MODE2 which is already used in the 118-152 MHZ extended range AM COM BAND.

    Yes there is an extended range AM COM BAND WHICH covers 118-152 MHZ already so nothing is really changing, all that will change is the primary user status of 144-146 or possibly even 144-148MHZ.

    Also why are we talking about 138-144 and anything above 146 MHZ or above 148 (STILL TBD) as all they are going to get is 144-146MHZ primary usage and possibly 144-148, and it isn't going to be for AM ATC modulation either nor is it going to be FM it will be secure telemetry control data.

    Must be a regional thing or just around Governmental Facilities. Other than a little bit of traffic in the VHF Marine Band, one frequency used for School Bus communications, and stuff in the 2-meter Amateur Band there is really nothing else to be heard from 138-174 MHz in my area. And, I live within VHF range (line of sight) of MacDill AFB, Central Command, a Federal Court House in Tampa and a CSX RR. Been scanning off and on for quite a few years and have never heard anything military or police in that part of the spectrum. Wish there was, it might make for some interesting listening.

    Not saying that there isn't something on those frequencies some where. But, nary a peep here.

    I never said it was and it's not land mobile radio, which is limited to 12.5 kHz bandwith or less on most frequencies in the US.

    All police and fire, state patrol, USFS, BLM, ambulance companies are all located there around here. Used very very heavy in my area. All wild land fire fighting is done in that part of the spectrum as well. I would assume in flat areas of the US lots of that has been pushed up to UHF and gone digital.

    who cares what they come up with.. I purchased my radio's with the intent of using them from 144.000 to 147.999.. they can pass any rules or laws they want , those frequencies in question will still be used no matter what the rules become..

    For the most part, isn't 2 meters one of the most well used bands? I would like to see a opening of the 4 meter band for North America. Paul KG7IRJ

    The French have a longstanding, innate need to surrender their rights whenever possible.

    Thales is the large French company that wants it.
    Germany runs Europe, the French won't get this.
