Understanding SWR
This decades-old video from Bell Labs gives the best explanation of SWR (standing wave ratio) I have ever seen. I enjoyed it so much I thought I would share it here.

As I was preparing to teach my winter 2024 course, IPT515 Artificial Intelligence for Instructional Designers (at Brigham Young University), I started thinking, “surely by now someone is applying AI to amateur radio.” It didn’t take a lot of Googling…
After conversations with friends in the WVDXA, I’ve begun using JTDX for working DX on FT8. Upon launching JTDX, however, I was immediately annoyed at the fact that it knew nothing about the thousands of QSOs I had already made…
Once I earned my General license in January of 2021, I didn’t imagine I would ever go for an Extra license. I heard several people say that the Amateur Extra exam was significantly more difficult than the General exam. And…
This video is absolutely amazing. Frank Howell K4FMH uses data from the massive eHams review database and Rob Sherwood’s massive collection of performance measurements to build statistical models that answer the question, “which HF radio gives the biggest bang for…
There’s currently a DXpedition to Mozambique operating as C92RU. I’ve been having trouble making a contact with the crew there, which surprised me a bit given how easily I contacted the same group a few weeks ago when they were…
For my first several weeks making contacts on FT8, in order to keep things simple I limited myself to making contacts with other hams who confirm QSLs via Logbook of the World. Now that I’m expanding into SSB I’ve started…
I’m continuing to be active on FT8. I recently read Gary Hinson ZL2iFB’s FT8 Operating Guide: Weak signal HF DXing for technophiles and it was extremely helpful. Check it out if you’re looking to up your game on FT8. I…
I put up my first HF antenna about four weeks ago. Suffice it to say that, in terms of ice storms, snowstorms, power outages, and internet outages, it’s been crazy here since then. But that’s not what this post is…
Last Friday, with the help of Tim K8RRT and Bob W8RLG, I got my first HF antenna up. It’s the EFHW-8010-2K-Plus Multiband End Fed Half Wave Antenna from MyAntennas.com. The marketing material for the antenna says: 130 Feet (39.6m) long…
