Random Links

Here are a bunch of random links to interesting and useful websites:

  • 1×1 Callsign Search. It’s often difficult to know who’s using a 1×1 special-event callsign. Looking them up on QRZ.Com doesn’t work because they’re only issued for short-term use, and they are re-used over and over. To help you identify that 1×1 callsign, the W5YI VEC has set up this searchable database. Type in a call, and it tells you who’s used the call recently and who will be using it in the near future. Very cool.
  • Arcane Radio Trivia. True to its name, this blog has all sorts of radio trivia. For example, a couple of the latest posts cover a 1920s radio show called Midnight Frolic that ran on WMC in Memphis, TN and the February 1930 issue of Radio News magazine. The latter is available as a PDF for download.
  • This item is from the 9/1/10 ARRLĀ Contest Update: Why is 10.7 used to determine the solar flux index? Spaceweather published this interesting article that explains why.
  • Radio Sky Publishing: Resources for Amateur Radio Astronomers, Students, and Teachers. If you have any interest at all in radio astronomy, check out this website. It’s been very slow for me, though, so be prepared to wait. I’m waiting right now for the “Beginner Tips” page to load.

    Thanks for the links. Will definitely bookmark the 1×1 lookup. Interesting that 10.7 cm turned out so lucky. 73, Elwood, WB0OEW, Tucson, AZ.

  2. Good afternoon Dan, the 1×1 call-sign search is great. I have done as you said punched a call into QRZ and comes up blank. In contests sometimes I come up against a call that is a 1×1 I like to look it up later and see that the call was about. I have bookmarked the site thanks very much!

  3. Dan,

    I think you might find http://www.1x1callsigns.org/ an even more capable site for researching 1 x 1 callsigns.

    Thanks for the 1×1 call site. This just reinforces my belief that there is so much good information out there that many never know about. Thanks for sharing this one.
