WHAT HAPPENED AT THE MAY 2, 2019 SDXA MEETING?

Sunday, June 16th, 2019

Mel N7GCO gave an introduction to the newest digital mode by Joe Taylor and friends called FT4.

In Show and Tell,

Several hams showed off their projectile air “guns” to launch a weight with a fishing line over tall trees to eventually be able pull up a dipole, inverted V, or other wire antenna. A fly fishing rod was even shown for those who know how to manipulate the skill. Among the presenters were:

1. John (K7KB) “Serial rotor control box” – but the internet connection at the library was not behaving.
2. Mike (K7STO) “NON-Tennis Ball Antenna Launcher”
3. Harold (AD7QJ) “Tennis Ball Antenna Launcher”
4. Bob (K7TM) “Antenna Launcher #3”
5. David (WA7TNT) “ICOM AH-4 Modification” – He showed his modifications to the ICOM AH4 remote tuner so one can disconnect the control cable and coax from the unit without going inside it, which is a feat due to the number of small screws and a very thin formed gasket.

2. G3TRP Trevor Preece: THE THE VHF/UHF DX BOOK, 2017 Replica Edition

The VHF/UHF DX Book was written in the early to mid-1990s by a team of experienced VHF/UHF DXers and equipment developers, in an effort to pass on our knowledge and stimulate further developments. Looking back, that plan worked very well… for a time. But as we entered the digital age, information of lasting value became trapped on the printed pages and was lost to the next generation of VHF/UHF DXers.
This digital replica of the Second Printing dated 1995 has been released by permission of the copyright owner TRPublishing and its proprietor Trevor Preece G3TRP.

HAPPY PI DAY

Saturday, March 16th, 2019


Today, March 14, is commemorated as international PI day in honor of one of the most important numbers used in our understanding of the physical universe.

Pi is an irrational number, which means it cannot be represented as a simple fraction, and those numbers cannot be represented as terminating or repeating decimals. Therefore, the digits of pi go on forever in a seemingly random sequence. It is the ratio of the circumference of a circle and the diameter of a circle.

Circumference = pi times D where D is the diameter of the circle.

The first hundred digits of PI are:

3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 …

And I see that the restaurant Shari’s is offering a free piece of PIE for a ten dollar purchase on Pi Day to existing signed-up customers. A fancy play on words there.

BOB ZAVREL W7SX & EZNEC AT THE 2/7/2019 MEETING

Friday, February 22nd, 2019

Antenna Modeling Orientation — Another great presentation by our local best selling ham author and ARRL Technical Advisor W7SX Bob Zavrel. It was an introduction to “Antenna Modeling”. He focused on EZNEC, which is by far the preferred software program tool for amateurs.

There will be a free follow-up workshop on EZNEC when the weather is better and more safe. We will let you now ahead of time. This now gives you more time to obtain your EZNEC software.

For those that want to use EZNEC, you can purchase it and install on your computer and bring to the workshop. Here is a link to the NW site that sells it:

Bob is the author of the ARRL published book entitled “An Introduction to Antenna Physics“, available from the ARRL or Amazon.com.
