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.
