Sorry about not posting much here lately beside the Extra Class questions of the day, but I’ve been pretty busy with my work and I really do Here are some more links to ham-related items on the Internet:
Cat sends Morse Code. I love cats, and while there are many videos of cute cats on the Internet, here’s one that shows a cat sending Morse Code. (Well, not really, but if you watch, you’ll see what I mean.) As I was watching this video, and then viewing a couple of other cute cat videos on this site, I noticed that my cat, Poochie, who was sitting on my lap, was intently watching the videos as well. That’s the first time that I’ve ever noticed that he was interested in what was going on on my computer screen.
IARU Region 2 band plans. A year from now, the IARU Region 2 General Assembly will take place. On the agenda are new Region 2 band plans. These band plans set the framework on how we use our bands and what modes we use in specific frequencies. If you’re interested in this topic, this Web page contains information on the current band plan and the procedure that will be followed for updating them next year.
Tek hypes ham radio.Tektronix, the big test instrument manufacturer, has many hams working for them. Perhaps the most well-known is Alan, W2AEW. I’ve blogged about him before. He has produced a really great series of videos on YouTube. He’s now blogging on the Tektronix website, and his latest post is an introduction to amateur radio.
Here are a couple of Internet resources to start off the week:
W2AEW on YouTube. Alan, W2AEW, has a great selection of cool videos on YouTube. Some of the latest cover the basics of phase-locked loops, how to zero-beat WWV to check out a frequency counter’s accuracy, and a tutorial on resonant circuits. Good stuff!
Baking Pi – Operating Systems Development. This course, published by the University of Cambridge Computer laboratory, is a free online course that takes you through the basics of operating system development. The Web page notes, “[This course] is aimed at people aged 16 and upwards, although younger readers may still find some of it accessible, particularly with assistance….I have tried not to assume any prior knowledge of operating systems development or assembly code. It may be helpful to have some programming experience, but the course should be accessible without.”
Classic Exchange. Mac, WQ8U, wrote to the Glowbugs mailing list, “The Classic Exchange (CX) is a low-key, on-air celebration of rigs of days gone by – particularly boat anchors. The latest CX Newsletter is available on the CX web site, as well as details for the next CX on September 16th (for AM and SSB) and September 23nd (for CW). Please enjoy the newsletter, spread the word and join in the fun during the next CX.”
Here’s some more interesting stuff that I’ve run across on the Internet:
- HamInfoBar. This toolbar, which is available for Firefox, IE, Safari, and Chrome, give you easy access to a wide variety of net info, including callsign info, APRS station info, eQSL data, and electronic component data.
- Area51 ham radio forum. Area51 is a set of bulletin boards. Some hams are trying to establish a ham radio forum there, but they need a minimum number of “followers” to do so. Click on the link and follow the forum.
- Simple Ham Antennas. This ham-radio blog, written by KH6JRM, has some very specific content – all of the posts describe simple antennas that can be home-brewed. For example, the last three are a 40m – 10m loop antenna, a vertical antenna for 40/20/15/10m, and stealth antennas.
Here are three more interesting links that I’ve gleaned from the mailing lists and ham radio groups that I belong to:
- G8MNY Technical Bulletins. G8MNY has been providing these technical bulletins over the packet network in Europe for many years. They were written by many different authors and cover many different topics including aerials, baluns, filters, microphones, and more.
These last two are from the LinkedIn amateur radio groups. If you’re on LinkedIn, send me a connect request and I’ll add you.
- Tubebooks.org. This site has PDFs of many older electronics books. Among them:Audels Radiomans Guide, Edwin P. Anderson, 1945, 880 pages
An odd book, about 4-1/2″ x 6-1/2″ and a whopping 880 pages, “covering theory, construction, and servicing including television electronics”. It covers everything from sounds waves through basic electronics, PA systems (including a little info on a WE theatre amp), transmitters, car and aircraft radio, troubleshooting – you name it, it’s in here. Not a college text, this looks like it could be a handbook for the radio technician or advanced hobbyist of the 1940′s. Lots of good vintage info!
- Slim Jim antenna calculator & Slim Jim information. I always thought that “Slim Jim” was just another term for J-pole. I was wrong. This site not only explains the difference, but has a calculator that lets you design your own. Now, I’m going to have to build one of these!
If you use QRZ.Com at all, you’ve probably noticed that they’ve started running a lot of political ads, namely ad criticizing President Obama. Now, I don’t have any insight into AA7BQ’s financial status, but I think running any kind of political ads on a ham radio site is just plain wrong. I’ve donated to QRZ.Com in the past, but I think if these political ads continue to run, I’m not going to contribute in the future.
What do you think?
I just finished a QSO with John, KR4RO. What is remarkable about this QSO is that it probably would not have occurred if we hadn’t first made contact on Twitter. John, who is @kr4ro on Twitter, and he and I follow one another there. Apparently, he saw my tweet (a tweet is a message posted to Twitter) that I was calling CQ on 7026 kHz and waited for my QSO with Vin, W1IDL to end and then called me.
John mentioned that he hadn’t been on CW for quite some time, and that he was kind of nervous. He did just fine, though, and I was very flattered that he would go out of his way like that to contact me.
I think more hams should use Twitter. It could open up a whole new world for hams. And, as my QSO tonight proves, it can even encourage some to get on CW, and as we all know, we can never have enough CW ops on the air. If you already use Twitter, please follow me there. I’ll be certain to follow you back.
Speaking of W1IDL, my QSO with Vin was remarkable on several counts. First of all, there must have been some weird short skip going on because he was 599 plus 20 dB here in Ann Arbor, even though he was located barely 50 miles away.
Secondly, it was notable because we had such a great conversation, even though this was our first QSO. Right off the bat, he started asking me questions about Ann Arbor and what I did here. I looked him up on QRZ.Com and found out that he was also a Rotarian and asked him about the club he belonged to. All in all, it was a memorable QSO.
Google+ has really caught on with hams. There are quite a few of us on this new social network, and I currently have 330 in my ham radio “circle.” Here are a few links that those hams have shared:
The KC5FM Daily. Paper.li is a website that lets you turn Twitter, Facebook and RSS feeds into online newspapers in just a few clicks. Here’s KC5FM’s paper.
‘UHF’ Connector Test Results. This blog post by John Huggins (I couldn’t find his callsign anywhere on the website) shows the results of his UHF connector tests. He also compares their characteristics to other types of RF connectors. Huggins says,
The stunning result is all the UHF connectors in the test have worse performance than all the other connectors. One immediate conclusion concerning ‘UHF’ connectors is they will function at these higher frequencies, but one must decide if using the PL259 or SO239 is worth it in an age where its deficiencies have been made moot by ALL connector designs since WWII.
Prywatna Wytwórnia Lamp, where DIY meets vacuum electron devices. This blog post describes another guy–this one in Poland–who makes his own vacuum tubes.
Google+ is a lot better site for ham-radio social networking than Facebook. Give it a try and join us.
I often joke that I have the #1-rated ham radio blog. I quickly go on to say that what I mean by that is that if you type in “ham radio blog” or “amateur radio blog” into Google, I come up #1. Of course, that’s practically meaningless. I mean how many people are going to type that into Google.
So, I thought, I’ll bite the bullet and see where I rank if I type just “ham radio” or “amateur radio” into Google. Well, lo and behold, I just came up #7 for “amateur radio” and #8 for “ham radio.” Honestly, I’m kind of amazed by that.
At any rate, I apparently got the search engine optimization (SEO) thing down. Now, all I have to do is figure out how to take advantage of it. <grin>
