LETARC Fox Hunt for Spring 2018 is GO!

The LETARC-sponsored 2 Meter Spring 2018 Fox Hunt event is a “GO!”

The hunt will be on Saturday May 19, 2018, with official Participant Registration beginning at LeTourneau University in Longview, Texas at 8:00 AM CDT.

The Fox Hunt Rules and Fox Hunt Procedures documents are included below. Dave, KL7BX and our LETARC Fox Hunt Coordinator explains, “These Fox Hunt documents are very detailed, and should answer 95% of whatever questions you may have, concerning logistics and event performance.”

Please review both the LETARC Fox Hunt RULES and the LETARC Fox Hunt PROCEDURES thoroughly. They include important requirements and will help you know what to expect on the day of the hunt.

We’d also appreciate it if you’d RSVP using this form. This will give our planners a better idea of who is going to participate, and—just as importantly—will give us a way to contact you if there is additional information we need to send before the event.

Radio-Direction Finding presentation by KL7BX

Dave Luchak of station KL7BX was kind enough to pass along his presentation files for his recent presentation Fundamentals of Radio-Direction Finding (RDF); Otherwise known as “Fox-Hunting.”

Dave’s presentation included some excellent statistics and tables, and the word “Fundamentals” in the title rather undersells how splendidly wide-ranging the presentation is. There’s more here than just “point and look at the signal strength.”

There are three files below, each with the same content.  The PPSX is the Microsoft Powerpoint 2007 format, the PPS is the Microsoft Powerpoint 97/2003 format. For the folks who are unable to view Powerpoint files (or prefer not to download application files), there’s a PDF version as well.

Thanks, Dave!

Jerry Ritchie Presents: Smith Charts

From Jerry Ritchie of station WA5OKO:

The HP-8753C Vector Network Analyzer cost $30,000 when it was new. Its weight is about 50 pounds and takes up a lot of space on my work bench.  It was one of my first instruments that provided Smith Charts.  20 years later, they about the size of a pack of cigarettes  and cost about $400 and have a range of 1 MHz to 3 GHz.  The MiniVNA Tiny’s size makes my MFJ-259B look like a boat anchor.

I compare the VNA instrument to the original cell phone. When cell phones first came out, I couldn’t imagine why I would ever need one.  Most amateurs look at Smith Charts like they are something from outer space, but they will eventually talk about that SWR meter they used in the old days to test antennas.

I hope this article will make the transition a little easier.

Jerry, WA5OKO

From humble beginnings…

On the plus side, the photos of sandwiches and coffee are largely absent from the website now. Things are a bit Spartan at the moment. A bit of color and glitz will be along in due course.

The club events calendar is hopping, though, so it seemed best to get the current events online soonest.

New LETARC Website Build

Welcome to the home of the up-and-coming LETARC website.

The new website installation package went live a few minutes ago. For a short time, it’s loaded with the default package software, which appears to be some sort of cafe page. That’s going to change shortly.

The old website has been moved off to the side. Once all the bits and pieces of the new site are well-underway, we’ll remove  it.

Thanks very much,

Ross, the new website administrator
