Look up an Amateur Radio Callsign prefix:
 
Try the whole call first, like TX0DX,
or then try just a prefix, like 9M6 or BD


Prefix not found? Perhaps the prefix has been retired. Check here: History of CTY.DAT revisions.

I write the propagation columns for the following magazines:

CQ Magazine CQ Magazine America's fastest growing magazine for the active ham radio operator. CQ is the world's leading independent magazine devoted to amateur radio. For more than a half-century, CQ has been on ham radio's leading edge -- the first to promote mobile operating (in the 1950s), semiconductors (in the 1960s) and packet radio -- the original e-mail (in the 1980s). The amateur satellite program got its start with an idea in the pages of CQ!

CQ VHF Magazine CQ VHF Magazine It is back! May 2002 saw the return of this quarterly magazines that focuses on amateur radio above 50 MHz. Articles and columns target both the beginner as well as the expert.
