Our next club meeting will be on Tuesday, August 7th; our club officers will present an AREDN update.

If you enjoyed today’s Lecture and Lab, or if you missed it, you can review the antenna dimensions on-line, or contact the club if you have any questions.

This coming Monday is going to be the 5th Monday of the month, so instead of one of our regular nets, we’ll be having trivia night on the air. Get ready to compete against the smartest hams in the area!

Tonight’s Afterglow Movie will be The Green Hornet, and if you can put up with commercials, you can watch it for free on-line.

On the contest calendar, the main stand-out is the RSGB IOTA contest, in progress now, but you’ll have to get moving: the contest ends at 7:00 am tomorrow, Dallas time.

The contest calendar has a few events this weekend. The CQ WW VHF contest is on, and challenging; the RTTY installment of the North American QSO Party is taking place as well.

The next Dallas Amateur Radio Club Lecture and Lab will be happening a week from today; come on out and build the easy 2-meter antenna discussed at the last meeting!

There hasn’t been too much in the way of ham news; it looks like Slovenian amateurs have received a new 60-meter allocation; it overlaps with two of our channels.

Moon Day is coming up in less than a week! Don’t forget to volunteer!

There’s only one big event on this weekend’s contest calendar: the IARU HF Championship. You get multipliers for working national club headquarters stations!

In ham news:

Some rule changes have been announced for the CQ WW contests. Most notably, the penalties for busted exchanges and missed log entries have been slightly reduced.

The ARRL reports that a ham technology—a low frequency radio phone—helped in the famous cave rescue that just took place in Thailand.

Links from Meeting Presentation 07-10-2018: Beyond the J-Pole

coil crop DSC_2208The response and interest in my presentation was great! Here are the links from the presentation and the details of my antenna build. Remember, we’ll be building this antenna at the July 28th, 2018, Lecture and Lab.

My modifications to the design by F3WM:

If you want to reproduce my design exactly, use CQ-118 from The Wireman.

I wanted full 2-meter band coverage; I used a 19 11/16” (498mm) upper section and a 19 3/4” (500mm) lower section instead. His size will work better in a radome, if you want to weatherproof the antenna.
