During the July 2020 DARC Board Meeting, the issue of noise on the DARC 146.880 repeater was discussed. Tony NT5TM did a street level inspection July 10, 2020 and noted NO issues or apparent damage to any of the antennas. A plan was formulated for an early repeater site inspection Sunday July 12, 2020.Continue reading
The 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.
We will have several extra sets of parts at the August Lecture and Lab, so don’t panic if you forgot to pre-register. What should you bring with you to the build?
At the very least, you’ll want to bring your choice of feedline connector. For many hams this will be a panel-mount SO-239, but you might prefer a panel-mount N or BNC. You’ll also need to bring some electrical tape, and possibly some coax if you want to test your antenna. A soldering iron and some solder will help you make much stronger connections.
Our August, 2017 Lecture and Lab will focus on the same antenna we discussed at our July meeting: the homebrew Buddipole. This is a simple, lightweight antenna that performs well, and if you visit our Lecture and Lab, you can leave with a finished antenna for your station or go-kit.
The July 11, 2017 DARC club meeting will feature an antenna building presentation by Tony Medina (NT5TM). Join the DARC crew for this exciting presentation details on the meeting location are here on this link.
Tony will present about building a homemade Buddipole portable dipole.
If your’re interested in building a clone of the Alphamatch, a.k.a the “magnetic longwire balun” that was discussed at the October 4th, 2016 meeting, here are some links you might find helpful. I’ve added a link to my hand-out from Tech Net on the Hill!
The End-Fed Half-Wave tuner we built at yesterday’s lecture and lab really does work! I disconnected the tuner from my base rig and cut some wires to the “30 meter” length printed on the PCB. The half-wave wire was tied to an old railroad spike that I threw up into a pecan tree. The counterpoise is sort of lying on the back deck.
June 19, 2016, White Rock Lake Park Dallas Texas – Club President Tony – NT5TM and Vice President Bill – KF5ZBL working on the portable HexBeam from foldingantennas.com fine tuning the elements – should be all set for 6M-20M work for Field Day 2016 all bands 2.0 SWR or better. Bill talked to NPOTA activators and then DX from Italy, Belgium and more.
A group of us will meet at White Rock Lake Park in Dallas June 5, 2016 around 10:30am for antenna test/setup and radio gobox shake down. Will try the TP Hill Pavilion first but it is sold out or in use monitor the 442.425 machine for the alternate site.
