    • FCC Callsign Lookup
      We'd love to hear what you think about our new FCC Callsign Lookup tool. Like it? Don't? Want something improved or changed? We do have future plans for it, but we're hoping that you like what we've done with Phase 1.

      Please note that unlike some other lookups, ours is updated daily with the FCC daily dumps.

      A big thank you to Michael Edwards for programming this baby from scratch. I especially love the local time dial, perfect to know what time of day it is at my contact's QTH.

    • 2020 New Year's radio resolutions
      So, does anyone have any New Year's / New Decade radio resolutions? Mine are to build at least one new, full antenna this year, and to possibly build a new go box with a different HF/VHF/UHF setup than I have now. Oh yeah, and to participate in the Vienna QSO Party with my buddies @K3HLT, @W3JRD, @KW4TO, and @W4DOI. In fact, let me take this opportunity to wish you all a very happy new year!!! And remember, you don't have to buy stuff to be happy, you can also make stuff!!

    • Christmas gifts
      Every year it's the same thing, someone who knows a ham asks me if I have any ideas on what to gift. I noticed that DX Engineering even produced a video giving suggestions. It's a tough one. For instance, their first suggestion was a headset. Well, if you don't know the exact radio, and most non-hams won't, then you will possibly buy a headset with the wrong mic or adapter. A book? Tough one also. I actually believe that buying something for a ham, as a non-ham, is likely one of the hardest tasks. I'm curious if anyone has any advice. Did I mention that I am a Ham and that Christmas is coming up?? 😃

    • Contest University
      So, last year I went to Contest University with @W4DOI. That was Alan's second year, the year before he had gone with @W3JRD. I must say, I enjoyed it. This said, I did find that it was a little more skewed to general operating than I would have thought. I was expecting something far more focussed on contesting per se. Would I recommend it, even to experienced hams? Actually, I would. You meet interesting people and you do learn new things, no matter how proficient you are.

      If anyone else has been to Contest University, I invite you to chime in. And if anyone has any questions I might be able to answer, feel free also.

    • I have a couple blind ham friends who are interested in trying FT8 and possibly other modes offered by the WSJT-X software package. One of these friends recently discovered a logging program called QLog that includes support for the visually impaired.  Qlog works with WSJT-X and provides a command set and audio prompts.  It does not require a screen reader such as JAWS.  There are commands, for example, to search for an open audio frequency, call CQ, call a specific station, or call any station that is calling CQ and passes a test defined by filters such as DX, new state, never worked before, etc.  Setup is best done with the help of a sighted assistant, as several parameters need to be set in QLog, WSJT-X, the rig used for operations, and possibly within the operating system on the computer.  

      The QLog program and setup instructions can be obtained by joining the QLogusers group on the groups.io web site and navigating to the Files section.  Among the files is a detailed description of the setup steps that the sighted assistant should help perform.  

      One of my friends made his first few QSOs this past week.  I'm still working on setup with the other.  The assistive features in QLog seem to be well designed and effective, but, of course, there is a learning curve.

      As of this date (November, 2019) there seems to be one significant item not covered in the documentation.  QLog will work properly when calling CQ only if the RRR message, and not RR73 is sent.  The sighted assistant may need to set up WSJT-X in this mode via a double left click on the TX4 button.
