(You may have been directed here from www.ke0og.net) You’ve landed on my ham radio home page. I’m KEØOG, an Extra-Class ham radio operator. I’m active on HF, 2-meters, and 440 MHz. I use this page as an index to ham-radio-related material on this site.
What is ham radio? Watch this video from the Radio Society of Great Britain (RSGB)
Current Geomagnetic Conditions for HF Bands
This chart shows various geomagnetic indicies and what the sun looks like now. These indicies show what HF propagation is like right now. You can use data like this to help you find a good HF band for operations. You can refresh this page to get the latest data.

Becoming a ham radio operator
- The three amateur (ham) radio license classes. Some background material on license grades, the difficulty of the test, and the operating privileges.
- Videos to aid your self study for your ham radio Technician Class license: Technician Class Ham License – On-Line Help for Your Self Study, which you can also access directly from
www.ke0og.net/training. The purpose of this series of videos is to talk you through the self study you’ll be doing with the ARRL Ham Radio License Manual. There’s one video for each section of the book, on the theory that it’s easier to study if someone’s given you a little overview. - A similar set of videos for General Class
- A similar set of videos for Amateur Extra Class
- Randy Cassingham’s intro to ham radio
- How much does it cost to become a Technician Class (entry level) ham?
- How much does it cost to upgrade to General or Extra Class and get on HF radio?
- What do I do once I become a ham?

- BaoFeng UV-5R+ ham radio — incredibly inexpensive dual-band handheld
- Programming the Wouxun KG-UV3D and the Baofeng UV-5R+
How I do it (which will be different from the way you do it, but it’s sometimes nice to have something to compare to)
- Using a rubber stamp to turn a spiral-bound notebook into a logbook.
- My new Yaesu FTdx3000. I review my new FTdx3000. Great radio!
- New addition to my shack: Oak Hills Research OHR100A 5-watt (QRP) CW 20-meter-only transceiver. See my notes and review here.

Special Techniques
- Packet Radio

- APRS: Making UI-View and Weatherlink Cooperate
- Interfacing the Byonics TinyTrak4 (TT4) with various handheld radios. Pays special attention to JP8.

Computer Issues
Miscellany
- Cool QSL cards from www.hamtoons.net. Jim is a cartoonist and can make colorful custom QSLs just for you. Here’s the one he sent me. He’s got a cool website worth looking at.

- App to create azimuthal maps based on where you live. Reader Rob, M6KOT, provides this link for those who want to make an azimuthal map based on your location. An azimuthal map shows the direction (azimuth) from your station to any place on earth and is handy if you want to know where to point your beam.
- Logging and QSLing for the Radio Amateur in the Electronic Age (narrated slide show). I gave this presentation on 20 Feb 2015 at a meeting of the Montrose Amateur Radio Club held in Olathe, Colorado. I added a narration to cover the main points and put it on YouTube.

Dave I want to thank you for all of your efforts in advancing the hobby for newcomers like me. I was able to successfully complete all three of my tests, in one testing session, thanks in great part to your training videos. I combined them with hamstudy.org and the ARRL manuals and pass. I have also learned a great deal from your “ask Dave” series. Please keep up the great work and thank you!
Hi Dave!
I used your videos a couple of years ago to study for my technician and general class license. Thanks for everything that you put into those! I know for sure when I decide to work on my extra, I’ll be back for more of your videos!
I remembered you are a motorcyclist as well. I saw your video going over Engineer’s Pass.
I am back on two wheels myself finally after 10 years of not riding. This time I’ve found myself on a Vstrom 650, and have quickly learned that I want to do more of this adventure riding thing. What better way to combine so many hobbies all into one?! Riding, camping, hiking/exploring, and now I’m adding radio on top of it all. I’m wanting to do things like SOTA, APRS, Winlink, and maybe even limited voice contacts through my Bluetooth helmet system too.
Have you done any motorcycle mobile installs, and/or made videos about it?
Right now I only have my new Kenwood TH-D74 to experiment with, but I plan on building a com box for the bike with my TM-D710, and eventually a 857d for HF too. Though the HF won’t be a bike mounted antenna, just along for the ride and used as a portable field set up at campsites and the like.
Thanks again!
