In this video, I review the QRPGuys.com End-Fed Half-Wave Mini Tuner. This is a $25 kit that will tame the high impedance of an End-Fed antenna. With this, you can deploy a half-wavelength of wire without feeding it in the middle (like you would for a traditional dipole).
Easy to build. Works great. A nice little kit for your building pleasure!
In this video, I explain how band-pass filters can reduce or eliminate QRM (interference).
Using a spectrum analyzer, I demonstrate a band-pass filter that I built based upon an article I found in the September 1988 edition of QST magazine. The article can be read here:
I went to Bonaire for two weeks, scuba diving and snorkeling. I wanted to take some radio gear.
And so I did… about 50 pounds worth!
In this video, I share with you the gear I chose to take and I reveal some important lessons I learned…
I got the last Mountain Topper QRP radio of 2015 from LNR Precision (according to Ryan).
I’ve been having a ball with this gem for the past 10 days. In this video, I tell you about the radio and then show you how to use nearly every feature. It’s a long video that I made for those who may be interested in this jewel-like little rig… which should be EVERYONE!
I went on a road trip with my friends Tim Kreth (AD4CJ) and Doug Miller (W4DML) last weekend to work portable from a beautiful scenic overlook. We drove about 70 miles, full of anticipation, only to find that the scenic overlook had been closed due to a hunting event!
We needed to make lemonade out of lemons.
Running out of time, we decided to head toward home and stop along the interstate at the first exit that looked promising. We found a field that was on an elevated exit of the interstate. It was getting late in the afternoon and we only had a short time to set up, make some contacts, tear down, and begin the drive back home.
I had planned to shoot some video footage for the blog but I only worked a few stations before having to tear down. I spent a lot of time trying to scare up some DX on 15m with no success. I did work Cuba on 15m and a couple of other stations on 20m. Tim concentrated on working 20m and had a lot of fun contacting stations participating in the Skywarn Appreciation Day event. Doug used the time to deploy and trim up a homebrew fan dipole that he’d built.
You can see my setup in the photo, below. You’ll see Tim’s setup in the distance.
Is there any better way to spend a Saturday afternoon than going somewhere with friends to play ham radio?
Taking advantage of the unseasonably warm weather here in Nashville (67 degrees!) I drove up to Bobcat Ridge and worked a few stations on 15 meters with 5 watts from my trusty Elecraft KX3.
Why don’t we make this a Black Friday tradition?!
My friend Tim Kreth (AD4CJ) sent me a couple of cell phone videos that he shot last weekend during the ARRL Sweepstakes contest.
Tim was only using 1/10th of a watt and he made a number of contacts. Here are a couple of them…
In this video, I show you one of my favorite places to work portable on Sunday mornings. (It’s a business park a couple of miles from my house and nobody’s working there on Sunday mornings.)
I made a few contacts (one shown in the video) before I rode my bike home to watch football.
I finish the video by making an argument for the Elecraft KX1 vs. the OHR 100A. To me, an internal keyer is a necessity in a CW-only QRP radio. That option pushes the OHR 100A up to $220. For $80 more, the Elecraft KX1 is a more capable, modern radio with a digital display – and it has upgrade options that aren’t available for the OHR 100A… like two additional bands (4 bands, total) and an internal antenna tuner.
Check this out. I worked a station today in Oregon with only 1/2 watt – on 20 meters in SSB mode.
Bad News: I forgot to push the Record button on my camera so I have no video!
Good News: I recorded the audio… so it DID happen and I can prove it…
My friend Andrew (AK4FA) asked me whether the vertical antenna I blogged about yesterday could be blown over in the wind.
Yes, it can! But here’s how to handle it…
