OCRA Club Meeting Monday, April 9th Presentation – The Lurid Details of a W4BOH antenna for Bouvet

When the Bouvet Island DXpedition was announced, some of W4BOH, Wilson’s DXer friends ganged up on him and urged him to put up a respectable antenna for 160m, since making a contact with Bouvet on 160 would be a real challenge. Or maybe they wanted company in the misery of not contacting Bouvet.

In any case, Wilson exercised his best management skills and recruited expert assistance from two of the DXer friends to help design and erect the antenna, which turned out to be a 57 foot top loaded vertical with four tuned radials. Always looking for a bargain, Wilson got W3AHL, Steve to adjust the EZNEC model to make the antenna potentially useful on other bands and in other configurations by changing the matching arrangement at the base.

Once the design was done, WA4PSC, Howie visited the Land of Magic and made two magnificent shots with his PBTBL (PneumoBallistic Tennis Ball Launcher) to get ropes over some of the highest trees at the OCRA/DFMA Field Day Site. At least the last two shots were magnificent. Steve then helped assemble some strong wire, of unknown parentage, into something resembling his design and helped pull it up into the ether. Of course his skill and analyzer were used to tune the radials to bring the antenna to resonance in the low end of 160m.

You’ll have to come to the OCRA Monday, April, 9th meeting to learn the lurid details of just what the beast (the antenna) looks like and what it can do on the air. Who knows, there might even be another story about getting a suitable amplifier assembled in time to contact (Or NOT) Bouvet some day.

Hams & Eggs at Virlie’s

An octet of hungry hams conclaved at Virlie’s in Pittsboro for the last breakfast gathering of the year this past Saturday morning.

John, KX4P, brought in a broken main frequency dial digital encoder for the group’s examination. It was from a Collins KWM-380 from the 1979-83 era that he recently repaired.

Dave, W4INN, determined to get on the air one way or another, is toying with the idea of just running anantenna wire out the window. Dave likes bees because he likes honey. His daughter-in-law gave him a whole jug of the stuff for Christmas.

Terry, KK4JGT, agrees. He has four hives now and a gardener neighbor who gives him produce in appreciation for his quadrupled yields since Terry became a beekeeper. With perhaps the best eyes in the group, he made several good observations regarding the shapes and orientation of the slots in the rotating disk assembly of John’s encoder.

Nick, KA1HPM, described working back-in-the-day with, and the workings of, the coordinateograph, a beautiful machine which is basically a highly precise Etch-a-Sketch. He is still puzzling out his mysterious loss of power on FT8.

Roy, WA2JLW, commented on the Bouvet Island DXpedition as well as CW and digital operations. He is now getting out of his back yard on 160 with his improved antenna which sports a pair of 30 foot radials.

John, KK4VUR, reports that Elon Musk’s SpaceX will attempt to put a car into heliocentric orbit on its next test launch. Maybe a Tesla? John confessed that he has been listening to HF on his SDR. (Ah, the HF siren beckons.)

Bill, N8BR, suggested that John try a vertical antenna for his HF SWLing. Bill is bracing for Bouvet.

Herb, N4HA, kept busy trying to remember what was being said so he could compose this. Thanks to KX4P for mnemonic assistance and the photo.

We hope you will join us in the new year for some stimulating conversation, friendship, and breakfast. We still meet around 8:30 AM.

Happy New Year to all.

and thanks to Herb, N4HA and John, KX4P for the always interesting reports and photo.


					

Herb, N4HA wins Third Prize in the ARRL 2017 Antenna Design Competition for his 20M Two-Element Wire “IV” Beam

A week ago, at the Pittsboro Virlie’s Grill ham’s breakfast, Herb Allred, N4HA, mentioned he had entered an antenna design competition and been awarded 3rd place. We all congratulated him.

Nick, KA1HPM, found Herb’s name in the latest issue of QST. What he discovered was that Herb had placed 3rd in the 2017 ARRL Antenna Design Competition for “80 through 10 Meter” antennas ! His design was for “A 20-Meter Two-Element Wire ‘IV’ Beam.”

See QST, November 2017, page 45.

This is a significant accomplishment with a cash award and possibility of publication !

Congratulation Herb!

Information web-page for hams in Raleigh

http://torborg.com/a
I created a web page to provide information for hams, originally new hams, but it kind-of got out of hand. The page is intended for hams in Raleigh, specifically, but much of the material is interesting for the surrounding region as well.  I wrote a repeater listing page which was intended to be more up-to-date than RARS’ page.  Now RARs links to my page.  Please comment if there is material missing that seems like it should be there and especially if the page is completely wrong about something.

I’d like to add a new page which lists the best repeaters for drivers in NC and in surrounding states.  145.21 and 442.15 are examples of wide coverage repeaters in this area.  What’s are some good ones useful while driving in other areas including in SC, GA, TN, WV, VA ?
Thanks for the help.
