I have written several electrical engineering books (see electronic-measurement.com). These books were written in the dead-trees print model, focused on creating a book that you can hold in your hand. I recently published VHF, Summits and More in both print and ebook editions. This was a learning process for me and I’ve come to understand a bit more about the differences between these formats.

Print

I definitely have a soft spot in my heart for a good-quality printed book. It is just plain satisfying to hold a printed book in your hand and flip through the pages. Moving quickly between pages and chapters is easy; very tactile with immediate feedback. I often look at our bookshelf at home filled with various engineering, ham radio, hiking and travel books. It just feels good knowing I can reach out to any one of them and access useful information.

Monochrome Kindle

Last year, we went on a long cruise and I wanted to have plenty of reading material while still traveling light. I did not want to drag along a big pile of books, so I purchased a monochrome (“paperwhite”) Kindle with the promise of long battery life and the ability to read it in bright sunlight. It delivered on both items. And it holds a ton of books (most of them I didn’t have time to read).

It didn’t take long to realize that the monochrome e-readers are optimized for plain text. They do pretty well with text-heavy books such as novels but aren’t very good for technical books that have photos or graphics. I mean, the display is only monochrome (and many of the readers are small.)

While creating my new book, I wasn’t really happy with how my book looked on the monochrome Kindles. It seems that there are some legacy formatting behaviors that cause them to present the text in some interesting ways. Also, the photos and other graphics really didn’t look that great. I was not encouraged and almost tossed the idea of publishing an ebook version.

Kindle Fire

Then I decided to purchase a Kindle with a color display, the Kindle Fire HD 8 tablet. This device has an 8-inch display and 16 GB of storage, costing $79. I downloaded the mobi file of my book to the Kindle and was immediately impressed with the presentation of the material. The photos and graphics show up in color and look great. Another added feature compared to print, is that the embedded hyperlinks allow easy to access to web-based information.

One thing I had to adjust to was losing some control over how the Kindle displays the book. With a print book, you have absolute control…put each comma, period, character right where you want them and they stay there. On the Kindle, the reader gets to make a lot of decisions: font type, font size, color, line spacing. While the author gets to choose the words and graphics, the final presentation is in the hands of the reader.

Read Kindle on Non-Kindle Devices

Amazon has done a fantasic job of supporting Kindle books on a variety of hardware platforms. You can get a free Kindle reader for both Windows and Mac. Mobile devices are supported, too, with their own readers (iOS and Android). The mobi (Kindle) file format is dominating the ebook market so I don’t have any plans to add other ebook versions.

You can check out the Kindle version of VHF, Summits and More on Amazon.

Here’s some more good stuff flowing forth from the interwebz.

HamRadioNow has a video of Laura Smith’s (FCC) talk at Pacificon. There’s lots of good info here on FCC enforcement activity. Gary KN4AQ produces some of the most valuable amateur radio video content on the web. How else are you going to see someone from the FCC speak about ham radio?

Sterling/NØSSC and Marty/KC1CWF have started the Phasing Line ham radio podcast, talking ham radio with a younger person’s perspective. They are on episode two…give them a listen. Look for them on the usual podcast feeds, or go here: n0ssc.com

I was interviewed by Eric/4Z1UG on QSO Today. Yeah, probably boring as heck but you’re reading this blog so your standards must not be very high.

The ARRL is cranking up an initiative to encourage collegiate ham radio clubs. Good idea.

DX Engineering visited the new venue (Greene County Fairgrounds) for the Dayton Hamvention. See DX Engineering visits the NEW 2017 Hamvention® venue and the drone video by Greg/W8WW that provides an aerial tour of the fairgrounds. I am looking forward to attending Hamvention next spring, the first time in many years.

Use Phonetics: HamRadioSchool.com republished their classic article on the use of phonetic alphabets. Also, take a look at my Shack Talk article on the same subject.

While reviewing the Technician license exam questions, I noticed that SWR is referred to as “2 to 1” or “1 to 1”. I see this as old school terminology…a ratio can be expressed as a single number: “my SWR is 2.” This triggered some discussion and a KB6NU blog posting.

That’s it for now. Happy interwebzing.

If you want to spark a conversation at your next social event, ask everyone the proper name for this symbol: #. Most North Americans will probably say pound sign or perhaps number sign. It helps to have an international audience, since a person from the UK will likely call it the hash symbol. Lately, the world of Twitter (and other social media) has made extensive use of # to tag keywords, referring to it as the hash mark used to create hashtags. A musician might claim that it is the sharp symbol from musical notation but closer examination reveals that the sharp symbol is quite different.

The AT&T engineers working on the original DTMF system adopted the name Octothorpe for this symbol. There are various explanations and anecdotes that have developed over the years concerning how this happened. Various forms of spelling show up in the literature (octatherp, octothorp, etc.). Doug Kerr’s story is particularly interesting and available on the internet (see below). There are US Patents that use the word “octothorp” to refer to the # symbol. Patent number 3920926 uses “octothorp” for # and “sextile or asterisk” for the * symbol. The term sextile never caught on at all.

For amateur radio usage (North America bias), I hear mostly pound for # and star for *. I suspect that will not change any time soon.

I’ve been blogging here and there about the TWiT Network’s Ham Nation show. I kept thinking that one of these days, I should pop into the TWiT Brick House Studio in Petaluma, CA for a look. I often travel to Santa Rosa for business, flying into San Francisco International Airport and driving up Highway 101 right past Petaluma.

When I noticed the announcement about the TWiT ham radio open house that was on the same weekend that I would be in Santa Rosa, I thought: Coincidence? Maybe. Fate? Probably. So Spousal Unit K0JJW and I swung by TWiT Headquarters late on Saturday afternoon.

It was great to chat with Bob Heil K9EID, Leo W6TWT and George W5JDX for a few minutes. I met a number of other hams that included Mike WT6H and Randy K7AGE (sorry, I don’t have everyone’s name & call written down). You may know K7AGE by his extensive collection of ham radio videos on youtube…if not, check them out. George W5JDX has been on Ham Nation multiple times now and has his own set of videos on amateurlogic.tv.

The radio guys were commenting about the high noise level on HF but I didn’t get a clear picture of the spectral content and what bands were affected. Things were actually pretty quiet by the time we arrived, but take a look at the video that K7AGE put together with footage from earlier in the day. It really shows the studio and the activity during the day.

The Ham Nation show is still finding its legs but gets better every week. It is clearly having a positive impact on amateur radio.

Ham Nation is On the Air, or should I say On the Network?

I previously posted about Bob Heil (K9EID) hosting the Ham Nation netcast on the TWiT network. The show is off to a great start with the first few episodes: The History of Ham Radio, Emergency Communications and Ham Radio Basics. You can view Ham Nation on iTunes or go to the TWiT website.

Check it out.

There are many email lists devoted to amateur radio topics, in particular on Yahoo Groups. These email forums are a great way to learn and exchange information. Usually these lists are created to hit a particular topic of interest. Over time, people stray off into other areas and start posting topics that are not appropriate for the forum. Eventually, the moderator steps in and shuts down the off-topic conversation.

What can happen next is the off-topic posters claim their right of “freedom of speech” is being violated. “This is America, and we have freedom of speech.”  (Kind of an odd statement since the internet is worldwide, not just a US concern, but I’ll set that aside.) This just happened a few days ago on an email list I use.

It has become all too common to hear people claiming “rights” that don’t really exist. US citizens might want to read the US Constitution once in a while, so they know what it actually says about freedom of speech:

First Amendment: Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

The US Constitution basically says that Congress cannot establish laws that abridge (limit) the freedom of speech. The amendment focuses on what the government is allowed to do to restrict the citizens. It does not mean that a citizen has the right to have their speech published in the local newspaper, sent through an email list, or posted on another person’s web site, etc. Newspapers, web site owners and moderators of email lists make decisions every day on what type of “speech” they are going to allow in their communication forum.
