Electromagnetics, the W8JK Antenna, and the ‘Wow!’ Signal

QRZ Now - Sun, 12/16/2018 - 8:03am

Electromagnetics, the W8JK Antenna, and the “Wow!” Signal 
Or, “My friend, the Ohio State Professor, Dr John Kraus, W8JK” 
Bob Houf

Antenna enthusiasts will recognize the call sign W8JK as the inventor of the classic array known as the W8JK flat-top beam. The antenna has unique characteristics that make it popular today and the interested ham can search the internet to find an almost overwhelming number of references for this design.

If you’re truly an old timer, you would know it as the ‘8JK flat-top beam antenna, originally described in the March and June (1937) issues of Radio Magazine and further discussed by Kraus in his QST article in the June, 1982 issue.

After spending 6 years in the Submarine Service of the US Navy I returned to school in pursuit of my Electrical Engineering degree at The Ohio State University. I had been an amateur radio operator as a 13-year-old teenager in 1963 and now it was the mid-1970’s and I was finally achieving my goal of obtaining my BSEE.

The first years went by at Ohio State and I began taking the core EE courses which included two semesters of Electromagnetics – starting with static charges, progressing through Maxwell’s Equations and on to antenna theory.

I was privileged to have as my instructor Dr John Kraus, W8JK , a distinguished Professor of Electrical Engineering and Director of the OSU Radio Observatory known as “Big Ear”. Dr Kraus had authored several text books on Electromagnetics and Antennas and his books were translated (sometimes illegally, as was done in the Soviet Union) in languages for use all over the world….READ FULL ARTICLE

How to configure WSJT-X without LOTW Error?

QRZ Now - Sat, 12/15/2018 - 7:01am

3.1. Windows

Download and execute the package file wsjtx-2.0.0-win32.exe, following these instructions:

  • Install WSJT-X into its own directory, for example C:\WSJTX or ` C:\WSJT\WSJTX`, rather than the conventional location C:\Program Files (x86)\WSJTX.
  • All program files relating to WSJT-X will be stored in the chosen installation directory and its subdirectories.
  • Logs and other writeable files will normally be found in the directory


Your computer may be configured so that this directory is “invisible”. It’s there, however, and accessible. An alternative (shortcut) directory name is "%LocalAppData%\WSJT-X\".

  • The built-in Windows facility for time synchronization is usually not adequate. We recommend the program Meinberg NTP (see Network Time Protocol Setup for downloading and installation instructions) or Dimension 4 from Thinking Man Software. Recent versions of Windows 10 are now shipped with a more capable Internet time synchronization service that is suitable if configured appropriately.

  • From this version onward WSJT-X requires the OpenSSLlibraries to be installed. Suitable libraries may already be installed on your system, if they are not you will see this error shortly after startup. To fix this you need to install the OpenSSL libraries.
    • You can download a suitable OpenSSL package for fromWindows OpenSSL Packages, you need the latest Win32 v1.0.2 Lite version (Note it is the Win32 package even if you are using a 64-bit Windows operating system) which at the time of writing was Win32 OpenSSL Lite Package.
    • Install the package and accept the default options, including the option to copy the OpenSSL DLLs to the Windows system directory (this is important).

If you still get the same network error after installing the OpenSSL libraries then you also need to install the Microsoft VC++ 2013 Redistributable component. From the download page select vcredist_x86.exe and run it to install.

If you cannot install the OpenSSL libraries or do not have an Internet connection on the computer used to run WSJT-X 2.0, you can download the LoTW file manually. Go tohttps://lotw.arrl.org/lotw-user-activity.csv in a web browser, download the file, then move it to the WSJT-X log files directory. This directory can be opened by selectingFile | Open log directory.

  • WSJT-X expects your sound card to do its raw sampling at 48000 Hz. To ensure that this will be so when running under recent versions of Windows, open the system’s Sound control panel and select in turn the Recording and Playback tabs. Click on Properties, then Advanced, and select 16 bit, 48000 Hz (DVD Quality). Switch of all audio enhancement features for these devices.
  • You can uninstall WSJT-X by clicking its Uninstall link in the Windows Start menu, or by using Uninstall a Program on the Windows Control Panel Programs and Features option or in Settings Apps on Windows 10.

Unboxing the New MFJ-2104 MFJ-2104 – Octopus Antenna

QRZ Now - Fri, 12/14/2018 - 7:50am

MFJ sent me their MFJ-2104 Octopus Antenna, a four-band dipole with screw-in elements for 75m (the voice portion of 80m), 40m, 20m, and 10m. This is built on a project in Dec 2007 QST by N1GY. The device uses any pairs of hamsticks on any band from 75 to 2m/440cm to create the four bands. It fits on a 1-inch mast. I’ll put it up and test it in a future video.

Octopus antenna hub turns your ham-sticks into four fully balanced dipoles in minutes!

Mix and match any four HF/VHF/UHF bands.

Example: screw in 80,40,20 meter hamsticks and a dual band 2M/440 MHz whip (two on each band) on opposite sides. Now you have an automatic bandswitching 5-band dipole! Rotate it for maximum signal and minimum QRM and noise with a small rotator like Hy-gain AR-500, $129.95.

Works at any height, low for local NVIS and high for DX. At a fixed height, (say 20-30 feet) use 80-Meters for NVIS and 20-Meters for low-angle DX.

Mounts on any mast up to 1-inch in diameter. Use a fiberglass pole on a tripod and you are on the air! Check out our MFJ-1919EX a perfect mount for the new Octopus Antenna.
Perfect fro casual portable operation, limited space, HOAs, field day, camping, and ARES during disasters.
Single coas feed, built-in balun.

Interaction between bands is minimized because the ends are spaced apart at a large angle.

You don`t need an antenna tuner if you carefully tune each dipole. An easier way is to just set each dipole approximately on frequency and use an antenna tuner to operate and widen the bandwidth. 

Hamsticks break down to four feet for easy storage.

Tough Octopus Hub
Eight 3/8-24 threaded connectors for hamsticks. Super stong fiberglass filled ABS base insulator. Your Octopus Hub will give you years of trouble-free service!
Based on Geoff Haines, N1GY, award-winning December 2007 QST article.

Super Octopus Deals
MFJ-2104, $249.95. Octopus hub with your choice of four (2 each) 250W Hamsticks. Saves $20! When submitting your order choose 4 of the hamsticks listed at the bottom of this page and write them in the notes before submitting your order.

MFJ-16XXT Hamsticks handle 250 Watts PEP. About 7 feet fully extended, 4 feet collapsed.

The first FT8 Roundup over the December 1 – 2 weekend attracted some 1,300 logs from those taking advantage of the ever-more-popular digital protocol. This, despite its having been announced on fairly short notice and with other contests such as the ARRL 160-Meter Contest under way on the same weekend. More than 400 logs were from US radio amateurs in the 48 contiguous states, plus the District of Columbia. Overall, some 131,200 contacts were recorded. Participants from 91 countries submitted logs, testifying to the fact that FT8 is not just an US phenomenon. 

“The FT8 Roundup was the last shakedown for the WSJT-X 2.0-rc5 beta software,” said well-known RTTY contesting enthusiast and expert Don Hill, AA5AU, an FT8 Roundup cosponsor with Ed Muns, W0YK. “It performed with no major complications.” The general availability release of WSJT-X 2.0 is now out, and it’s not backward compatible with WSJT-X 1.9 or earlier versions. Developer Joe Taylor, K1JT, has urged users to upgrade by January 1 to what now is new world standard.

Muns, who’s NCJ “Digital Contesting” contributing editor, said FT8 Roundup participation compared favorably with that for the ARRL RTTY Roundup, which has averaged around 1,700 logs in recent years.

“Don and I expected the contest to be popular,” Muns said, “but the participation far exceeded our expectations. I think it bodes well for future FT8 contesting. Don and I are pretty bullish about continuing the FT8 Roundup on the first full weekend of December each year.” Nonetheless, Muns said he doesn’t believe FT8 will “really take off” and displace RTTY until the contact rate can be significantly increased through parallel QSO techniques. 

Hill agreed on the event’s popularity. “I have to say it was a huge success,” he said. “Ed and I never dreamed it would be this popular. It didn’t make sense to continue the Ten-Meter RTTY Contest during this part of the sunspot cycle. Replacing it with an all-FT8 HF contest was the logical choice.” Hill and Muns also co-sponsor the Ten-Meter RTTY Contest.

Hill told ARRL that final results of the inaugural FT8 Roundup should be out in a few days. “After the New Year, we hope to have downloadable online certificates available to all participants. We will definitely do it again next year,” he said.

The 2019 ARRL RTTY Roundup will permit the use of FT8.
