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

Posted on by

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.

Springtime at Virlie’s

Posted on by

Springlike weather coaxed eight hams out of their shacks for the weekly breakfast and kaffeeklatsch at Virlie’s Restaurant in Pittsboro this past Saturday. If Spring was in the air, so were tales of LDE’s (Long Delayed Echoes). Nick, KA1HPM and John, KX4P were in a roundtable on 75 meters when they experienced delays of around 1 second on the signals of several of the participants. The phenomenon lasted for about thirty seconds per occurrence. One of the most popular extant theories is that signals are trapped between two ionized layers and are guided around the world several times before falling out of a hole in the bottom layer.

Roy, WA2JLW, loaded up some N1MM contest software and enjoyed playing in the ARRL DX CW contest the previous weekend.

Terry, KK4JGT, has organized our first emergency communications coverage test for Chatham County this Monday evening on the OCRA 440 repeater which the OCRA crew has generously allowed us to use during emergencies and training. Terry also described his copper pipe dual band J pole.

Bill, N8BR, had a motherboard crash, but retrieved the hard drive intact. He is working on also retrieving his old log files from that drive.

Dave, W4INN, is getting into the swing of spring by planning to do some gardening.

Pete, K4PHS, brought his newly constructed 30 meter WSPR beacon. Transmitting with 1 watt and a dipole in the attic, it has been received in Europe and Antarctica.

Herb, N4HA, hopes he’ll figure out how to program his new HT before the repeater test Monday evening.

Please join us for radio fun Saturday mornings at Virlie’s Restaurant in Pittsboro around 8:30 AM.
