>From time to time topband operators report hearing unidentified 'mystery'
beacons which often turn out to be harmonics of mistuned or nearby aero
non-directional beacons (ndbs) operating in the 200 - 530 kHz range. For
those so interested, there is a wonderful resource that is available in .pdf
format from: http://www.beaconworld.org.uk/info.htm
or directly from the editor (Andy Robins KB8QGF) at:
andrew.robins@wmich.edu
The list (now at 34 pages) is updated every month and lists (by frequency)
every ndb reported heard in North America, along with state, grid locator,
u/lsb ident frequencies etc. If you are interested in chasing down that
unidentified pest, Andy's list is a good place to start. If you are
interested in ndb DXing, it is even more valuable.
