    GQK:

    Probably vote for Labor Day, might for New Year's Day, since, at least on this side of "the pond", no special meal, especially one involving turkey, is served on those days. Definitely would not vote for Thanksgiving Day and probably not for Christmas Day!

    Well, maybe...but there's not much else out there for wide-area navigation. Omega has been gone for going on 20 years now. ;-)

    But seriously, I don't know what kind of radiolocation uses the frequencies at the upper end of 160. I know of aviation NDBs, but they all (IIRC) are below the AM broadcast band. Is it some sort of marine beacon service?

    Here is one: http://www.ominous-valve.com/hyperfix.html

    Note that "Hyperfix is rapidly being replaced by differential GPS. The once-loud chain in Los Angeles appears to have been shut down a year or two ago."

    Another one: http://www.blueoceantackle.com/longl..._equipment.htm (scroll down to the middle of the page)

    These things can still be heard in the band. Usually weak CW beacons; they run only 5 watts.

    Any idea why San Diego is specifically called out? I'm guessing this is related to the large military presence here?

    23. Current Federal use of the 1900-2000 kHz band is light, with 10 assignments that authorize
    operations in this band. A single Federal assignment authorizes land and mobile stations in the RLS to
    transmit on 1922 kHz using a necessary bandwidth of 600 hertz (Hz) within a protected radius of
    193 kilometers (km) centered on San Diego, California
    . All other Federal assignments in the
    1900-2000 kHz band are for unallocated uses, and thus, these assignments operate on an unprotected and
    non-interference basis.(55)
