ICQPodcast Episode 487 – A Taste of Ham Radio Friedrichshafen

July 12, 2026 By Dan KB6NU 2 Comments

ICQ Podcast logo.In this episode, I joined Martin Butler M1MRB, Caryn Eve Murray KD2GUT and Ed Durrant DD5LP to discuss:
  • Germany Likely to Get Full 4 Metres Band Back. The Brits on the podcast seem to love the 4-meter band. Unfortunately, I doubt that we’ll ever get access to it here in the U.S.
  • Eyeball-to-Eyeball Off-the-Air QSO Party. The Eyeball QSO Party is a weekly Zoom meeting that got started during the pandemic that continues to this day. Hams from different countries attend every week to share their opinions and activities.
  • Canada Reviewing Policy on Antennas, Towers. Although this effort isn’t specifically meant for radio amateurs, the Radio Amateurs of Canada thinks that the proposals will give hams much more latitude when it comes to putting up antenna structures.
  • Researchers Create Space ‘Wall’ to Weaken Solar Storms. Researchers believe they have developed an effective line of defence against geomagnetic storms that would protect radio communications, GPS systems, electrical grids and satellites from disruption. This is, however, all theoretical at this point, and the panel was dubious that this would work in practice.
  • YOTA Camp Region 1 – Austria July 2026. A highlight of this year’s YOTA Summer Camp is that every attendee will go home with a QMX+ they built, with the help of Hans Summers G0UPL of QRP Labs. Hans is also donating endfed antennas, power banks,  microphones, and Morse keys. I want to be like G0UPL when I grow up.
This episode’s feature is a Taste of Ham Radio Friedrichshafen.

From my inbox: Free antenna book, new zBitx, how to get back into the hobby

April 23, 2026 By Dan KB6NU Leave a Comment

I’m on a lot of amateur radio mailing lists, so I get a flood of information every morning. Here are three items I found amusing in this morning’s email…..Dan


Free antenna booklet

Jukka Siitari, OH2AXE/SV9RMU, has just published Amateur Radio Antenna Systems, and it is available as a free PDF. This 62 page guide was written for beginners, but more seasoned radio amateurs will find useful information, too. For example, I found the chapter on selecting and locating an antenna interesting.

This illustrated guide is available in English, Spanish, Portuguese, German, and Greek. Should you need versions in any of these languages, please get in touch with SRAL office by email: [email protected].

This 62-page antenna booklet contains many photos and illustrations.

HF Signals releases the zBitx v2

According to Ashar Farhan, the zBitx v2 is finally here! He writes:

The zbitx v2 is two things : it is an upgrade of the original zBitx radio and it is also a new zBitx software that  fixes almost all the issues reported by the users.e to the supply problems around the display and the raspberry pi zero 2W and increased freight and duties all around, our price to be be increased. the zBitx v2 now retails for $269 (including shipping).

This does look like a nice update to this very small rig. For more information, visit the HF Signals website.

The zBitx measures just 6.5”x3”x1.5” and runs off two LiPo batteries.

Redditor asks for help getting back into the hobby

Redditor Cold-Description-586 writes:

An old teacher of mine that became a friend had an interest in ham radio. He gained his technician license, bought a radio, antenna, power supply, and wired everything into a shed. It was fun and enjoyable enough that I became interested in it and passed my technician test while he got his general and started transmitting 10 meters. I found this to be really interesting, however, he passed way and my enjoyment of the hobby ended. I’m curious how I could rekindle my enjoyment for the hobby being I have no immediate friends that like amateur radio and have forgotten many techniques of the art.

Here are some of the replies:

  • Get into POTA!
  • If you still have some gear, just turn it on and start listening. Make a few contacts. If you don’t have any radios, tune around on a WebSDR and listen. See if that interest is still there.
  • Identify which part(s) of [the hobby] intrigue you, and focus on those.

What suggestions would you have for Cold-Description-586?

Videos: 44 years of 44Net, Linux HT, Super Rybakov antenna

December 17, 2025 By Dan KB6NU Leave a Comment

44 Years of 44 Net

44 years ago, Hank Magnuski, KA6M, asked for some IP addresses for ham radio experimentation. He was assigned a /8 block, or 16,777,216 addresses. We now know this block addresses as 44Net.

The Linux HT

Can you really run Linux on an HT? Yes! Watch this video and see how it’s done.

The Super Rybakov

This talk by Max, G4SDX, to the Halifax & District Amateur Radio Society introduces a hands-on build of the “Super Rybakov” – an improved version of the classic end-fed vertical antenna. This looks like a great limited space antenna with efficient, multiband, HF performance.

Amateur radio videos: Giving back, eliminating RFI, tall tower construction

November 11, 2025 By Dan KB6NU Leave a Comment

Giving back to amateur radio (and your community)

If you’re a regular reader of my blog, you know that I’m a big believer in giving back to our hobby and to my community. In this RATPAC video, Marty Woll, N6VI, a former assistant emergency coordinator and past ARRL Southwest Division director, offers many suggestions on how to do this.

Eliminate your high noise floor

 

A link to this video appeared on the amateur radio subreddit this morning. It shows you how to build a filter to eliminate any RFI coming in through the power line.

Constructing very tall towers

Watch this video before you put up a really tall tower of your own. If you’re curious about what it’s like to actually work on one of these towers, watch this video.

Urge your representatives to pass H.R. 1094 and S. 459

September 23, 2025 By Dan KB6NU 3 Comments

Last week, the ARRL sent out a member bulletin, exhorting hams to contact their U.S. representative and senators and urge them to pass H.R. 1094 and S. 459, the Amateur Radio Emergency Preparedness Act. According to Congress.Gov, this bill limits the adoption and enforcement of private land use restrictions (e.g., rules of a homeowners’ association) that prohibit, restrict, or impair the installation, maintenance, or operation of an amateur station antenna on property controlled by an amateur radio operator.

Contacting your representatives is very easy. All you have to do is go to https://send-a-letter.org/hoa/ and type in your call sign.

Here’s the text of the bulletin:


YOU CAN HELP US CHANGE THE LEGAL RIGHTS OF AMERICAN HAMS

The ARRL is focused on reducing legal restraints on the ability of American Amateur Radio Operators to engage in the active practice and enjoyment of Amateur Radio.

One of the most insidious and increasing threats to the survival of Amateur Radio and our ability to serve our communities and Nation, as we are required to do by Federal regulation, is the proliferation of private land use restrictions that prohibit the installation of outdoor antennas and that sometimes actually deny Federally licensed Amateurs from operating any amateur radios, regardless of where their antennas are located — in their attics, hidden in trees, or mounted on their vehicles.

Federal law — since 1996 — has guaranteed to every American — except Amateur Radio Operators — the right to erect antennas outside or on their residences for the purpose of TV reception, satellite TV and internet access, wireless internet access, and even wireless internet redistribution. But Amateur Radio operators are denied the equal right to erect comparable antennas.

Since 2005, Federal law has also guaranteed to every American the right to proudly display the American Flag by installing flagpoles in their yards. But, despite that right to install vertical poles in their yards — American Radio Amateurs are denied the right to use those vertical flagpoles as vertical antennas.

We believe the denial — to licensed Amateur Radio Operators — of the rights guaranteed to all non-Amateur Radio licensed American homeowners — the right to install antennas on the land they own — is without justiïfication and should not be permitted to continue.

To eliminate these private land use restrictions, the ARRL has worked over the past several years with our elected officials to draft Congressional legislation — H.R. 1094 in the U.S. House of Representatives and S. 459 in the U.S. Senate — that, when passed will extend to all Hams the right to operate from their homes and the right to install antennas on the land they own. We have bipartisan support for this legislation.

BUT, WE NEED YOUR HELP TO PASS THIS LEGISLATION!!!

How can you help? By sending a letter to your Representative and Senators asking that they co-sponsor and support H.R. 1094 and S. 459.
How can you send these letters? It is easy.

Go to https://send-a-letter.org/hoa/, enter your call sign and click on “Send My Letters” and your letters will be delivered to our Washington legislative team for hand delivery to your Representative and Senators.

Does your individual letter matter? YES.

Your Representative and Senators need to know that the passage of this legislation is important to you.
Your letter could be the difference in whether we are able to pass H.R. 1094 and S. 459.

Go to https://send-a-letter.org/hoa/ and help us by sending your letters to your Representative and Senators.

Stuff I’ve been meaning to read/watch: The Divided Dial, portable antennas, head copy

September 4, 2025 By Dan KB6NU Leave a Comment

Here are three things that I’ve had open tabs for in my browser for a week or more…….Dan

WNYC: Tuning into The Divided Dial

The Divided Dial is a podcast whose second season discusses the current state of the shortwave bands. This video is a look behind the scenes and a recap of the season.

Portable-Antennas.Com

portable-antennas.com is a non-commercial collection of easy-to-use online tools to develop and analyze wire antennas that are especially suitable for portable use. The tools were developed by Rob, DM1CM. I haven’t used many of the tools yet, but I’m certainly going to be analyzing my 66-ft. doublet with the tools on this site.

Antenna pattern diagrams.
Here are a couple of antenna patterns generated by the tools on portable-antennas.com

Head Copy CW, An Alternative Method: “Phonic Copy”

To copy Morse Code at speeds above 18-20 words per minute, you have to be able to copy code in your head. Most people simply can’t write faster than that. So, the question is how does one learn how to head copy?

In this article, Paul, N6EV, proposes the “phonic copy” method.  He writes:

Code is an aural representation of a phonic sound.” Each Morse Code element represents the phonic sound of a corresponding letter, not the letter itself.  This means, as elements (letters / numbers) are received, they are phonically pronounced in the speech / aural portion of the mind (the auditory cortex) rather than visualized graphically as letters or  whole words in the written / visual portion of the mind (the visual cortex).

I like this approach. I think it most closely represents the process that I use.

Does anyone make a homebrew SteppIR?

June 17, 2025 By Dan KB6NU 1 Comment

In case you haven’t heard by now, SteppIR, the manufacturer of very expensive HF antennas is getting out of the amateur radio business. Their announcement has caused a minor uproar in the amateur radio world, but personally, it’s not a big surprise to me. If MFJ couldn’t seem to find enough customers for their $300 – $500 Hy-Gain antennas, how many $5,000 antennas could SteppIR really sell?

What I’m surprised by is that no one has come up with a homebrew design replicating the functionality of the SteppIR antennas. The SteppIR design is quite complex—which is one reason that it costs so much—but hams are pretty creative. It seems to me that someone out there could replicate the SteppIR functionality for a lot less than $5,000 (the approximate price for a two-element SteppIR Yagi).

Perhaps someone has already. If you know of a homebrew version of the SteppIR antennas, please let me know.

Random Notes: KB6NU at the South Pole, operating W7P, RF in the shack.

April 9, 2025 By Dan KB6NU Leave a Comment

Amateur radio antennas at the NSF Amundson-Scott South Pole Station.

KB6NU at the South Pole (well, my study guides anyway)

A week ago, I got the following email from David Williams, who’s working at the United States Antarctic Program NSF Amundson-Scott South Pole Station. According to their website, “the station is the southernmost year-round research station in the world, and supports scientific studies in astronomy, astrophysics, aeronomy, auroral studies, geospace research, meteorology, geomagnetism, seismology, earth-tide measurements and glaciology. The station’s geographic location allows unique astronomical observations, benefiting from clear, dry air and the absence of light pollution.”

David writes:

Greetings,

I want to thank you for writing your study guide- A few of us down here for Winter are going for Ham radio licenses and part of the study materials we are using includes your PDFs.

Our equipment down here requires a General class at minimum. We would use it to contact McMurdo Station in an emergency.

I’m very new to the hobby but it’s really interesting to learn about! We will all go for our licenses after a few weeks of study likely.

How cool is that? I’m glad that they’re able to use my study guides, and I hope that a bunch of them get their licenses.

Operating W7P

Yesterday, I operated as W7P for the first time. W7P is one of the call signs being used for the Narwhal Amateur Radio Society’s Polio on the Air special event, which is commemorating the 70th anniversary of the Salk polio vaccine. Other call signs for the special event include W7O, W7L, and W7I. So far, I’m the only CW operator.

Last night, I made 25 contacts on 7035 kHz in about an hour. I worked stations as far west as North Dakota and as far east as Spain (my only  DX contact).   It was a lot of fun.

The even runs through Saturday, and I’m scheduled to operate tonight and Thursday night at 0000 UTC. You can listen for me again on 7035 kHz.

RF in the shack

Something wonky is going on with my trusty Cobra antenna, and I’m not sure what exactly. Somehow, I’ve started to get RF in the shack. I do run the ladder line right into the shack, but the antenna’s been up for nearly 10 years now, and this hasn’t been a problem.

One thing that I’ve been thinking about doing is to connect the 450Ω feed line to a balun outside and run coax into the shack. I’m also thinking that maybe I should rebuild the antenna. That would clean the contacts.

If you have any thoughts about this, please leave a comment below or email me directly.
