President’s Corner

April 2021

  We are slowly making provisions to return to in-person meetings! Steve Darrah, KD5YPB, has received approval from Carrollton Fire Rescue (CFR) to use the 2nd floor meeting room at CFR headquarters (Gravely Center) for our monthly meetings once Carrollton allows in-person meetings at city facilities such as the library. For the foreseeable future the libraries close at 8:00 PM on the “late” days which is too early for MARS meetings to end, so we are incredibly grateful to CFR for the use of their room.

  I understand that some of our members have concerns about meeting in-person. Luckily, most of us have received our COVID-19 immunizations and the overall infection rate in Texas continues to remain low. We will monitor the situation and hopefully we can again have face-to-face meetings sometime this summer.

  As reported previously in many places, Dayton Hamvention 2021 in-person was cancelled. Hamvention plans to return in May 2022. There will be a QSO party held on the same weekend—May 20, 21 and 22. There will be new free Zoom sessions covering ham radio subjects. The organizers are still working on the QSO party and the sessions so keep checking There are already over 4 hours of free videos posted, part of the “Propagation Summit 2021” held earlier this year. See this link for details:

  When I worked in the Computer Graphics division of Tektronix years ago, I knew that they made great test equipment. Years later I realized how close I was to some legendary—and very expensive—gear. Spectrum analyzers were especially “cool” and expensive. Well, here’s a cool gadget that every Ham should put on their wish list: a Spectrum Analyzer with a color screen for under $100! Check out these links:

  Everyone fire up a radio, go through your rig’s menus, read your owner’s manuals, spin the dial, and monitor a band. You might just learn something!

Kit Building—A Dying Breed?
A K2 Comes to Life Part III

David Duke, KM5YQ, continues his series about his Elecraft K2 build.

  The third phase of the K2 build is to install the remaining band pass filter, low pass filter and the transmitter components. Another decent size group of resistors and a large group of capacitors were the first big steps. Somewhat tedious, but these are the steps where it is important to take your time, and several breaks. After this, the build went much quicker as I had already pre-wound the remaining toroids. [more]
