In this video, I show you the portable hexbeam antenna I recently built. I discuss all of the components that are required to build one.
This is a great antenna that is a bit of a PITA to deploy… it has more parts and requires more setup time than a typical wire antenna. But, for special occasions, when you want a nice directional antenna to deploy in the field, this is what you need.
LNR Precision (www.LNRPrecision.com) recently released the first production batch of their new Mountain Topper 5-Band QRP radio.
The MTR-5B is THE new pocket-sized QRP radio to have. Highly Recommended!
As soon as I took it out of the box and hooked it up, my first contact was CN8KD in Morocco on 30m. I take that as as good omen for all of the fun I will have with this amazing little rig.
In this video, I show you the improvements over the (still awesome) MTR-3B radio. I then hook it up to an antenna and take it for a spin, letting you see the new four-line LCD display and some of the many cool features.
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:
Here are the basic tools that you will need for electronic projects. It’s a great time to tinker with electronics because there are so many radios, antennas, tuner, and other gadgets available as kits. Of course, you can “homebrew” your own gizmos, too!
Winlink lets you easily send/receive email from anywhere on the face of the Earth with your HF radio. This is a key component of disaster preparedness for hams who will step up and provide communications for others in a time of need. (The impending Zombie Apocalypse is reason enough to learn this, people.)
In the first 7 minutes, I give you the background information on Winlink… what it is, why it’s important, and how it works. Then, I fire up the computer and a QRP radio (naturally!) to do a demo of sending and receiving email.
I played around in the ARRL International DX Contest this weekend for a total of about 8 hours. During that time, I worked 49 countries!
I’m NOT a contester. I’m not really even all that great at CW but I do enjoy it. If I can do this, you can do this, too.
The contest exchange of information was:
DX Station: Call sign, Signal Report (always “599”) and Power Level
American Station: Call sign, Signal Report (always “599”) and State abbreviation.
In this video, I show you my station setup and then record my screen so you can see me working some DX stations via QRP.
Don’t miss the Bonus Track at the end of the video…
Want to get your head around the concepts and hardware needed to start using some of the amateur radio Digital Modes? You’ve come to the right place! This comprehensive video will tell you everything you need to know to get started and it lays the groundwork for a series of upcoming in-depth videos on RTTY, PSK31, JT65, and Winlink.
The following questions are answered in this video:
- Why Digital?
- What is Meant by Digital Modes?
- How Does Digital Work?
- What Kind of Radio is Needed?
- What Kind of Computer is Needed?
- Do I Have To Make My Own Cables?
- What Cables Are Required?
- What About Push-To-Talk?
- How Does A Signalink Box Make Things Easier?
- How to Connect Radios to a Signalink Box? (FT-817 and KX3)

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…
Using a well-known circuit, I show you how to build a simple computer interface so your logging software can send CW through your radio.
The logging software simulates someone using a straight key. It changes the voltage on an RS-232 pin and the electronic circuit uses a transistor as a switch, grounding the lines as though someone grounded the contacts of a straight key.
This interface will let you work a contest or pile-up using your logging software – without having to use a key or paddle.
