CW Works
radio : by Tommy - February 16th 2016, 04:32PM
radio
I posted earlier about my new MountainTopper Radio. They're only being made and sold in small batches so I was never able to get my hands on one until January 2016. When I visited the site and saw they were for sale, I jumped at the opportunity to secure one of the little radios and it arrived a couple of weeks later. I had a business trip to go on so I wasn't able to fully get to know the radio until I got home. After I got home, the following Monday I got on the radio with the manual open on my computer. I got a feel for all the features packed into the limited number of buttons. After a while I really got the hang of it.
The next night (Tuesday) was a NAQCC Weeknight Sprint (a mini 2-hr radio contest) and it was also a night when class was cancelled. The 40m band was in pretty decent condition that night and I easily nabbed 5 different states. At the conclusion of the contest I made a couple more contacts and decided I loved the little radio. I've been using it nightly for the past week, making at least one QRP CW contact each day ...and that's where I've learned something.

It's something I heard guys say over and over again and, like you reading this, I've seen others write about: CW Works.

It's not just some old geezer claiming his tastes/choice mode is superior. What I mean to say is when the bands are great or incredibly noisy, CW still gets through. To modify the slogan "When all else fails... CW". Sure, digital modes get through when conditions are equally rough. (I first learned that late at night during Field Day one year using PSK31.

MountainTopper Radio

It's been quite a while since I last made a post but this is one I have to mark the occassion for. For the better part of the past 6 months I've had my eye on the MountainTopper Radio. It's a small QRP CW radio designed by Steve Weber, KD1JV, and sold by LNR Precision. The model I got is the 3-band version. (At the time of this writing there are rumors stirring about an upcoming 5-band version. Since I'm really only active on 40m and 20m, I'll pass on the 5 band model.)

The radio is very small - about the size of a deck of cards. There's no internal antenna tuner or battery. The volume, RF gain, and filter settings are fixed so there's no need for adjustment knobs. Nor is there a tuning knob. Tuning is done by two push buttons (UP and DOWN) that nudge the VFO up or down 50Hz. Holding down the button will change the frequency in 100Hz steps at a rate of 10 steps per second.
The elimination of knobs on the face of the radio allows the radio to pack very small. It's so small in fact, I was moved to get a Micro key from KK5PY. It has to be the smallest paddles I've ever used. To match the small size, the MTR can be powered by a 9V battery or a small 12V LiPo battery pack. Pack in some earbuds, a wire antenna, and a paper logbook and the whole kit fits into a small padded, zippered case ready to go. It's a radio meant for travel! I can't wait to take it on the road with me.
I've been using it to make QRP CW contacts each day for the past week and I'm going to try to get QRP Worked All States on 40m CW.

HOWTO: Getting Started with CW
radio : by Tommy - October 18th 2011, 05:50PM

It's been a year since my post about Morse Code: Brief History, and I figure I might as well shed some light on how to get started operating with Morse Code. Since the Morse code requirement for ham radio was lifted in 2007, the number of amateurs getting their HF privileges has grown substantially, but with the "repeal" of code, entry level Technicians are granted privileges in certain portions of the bands. Most commonly, Technicians can operate SSB in the 10m band, but can also operate CW, or Morse Code, in 80m, 40m, 15m, and 10m. So, if you're a ham, you already have privileges to operate CW - you just need to learn where to start.

Learning the Code
For starters, you will need to learn Morse Code, one way or another. (duh.) While it may not be the universally agreed upon best way, I learned Morse Code through the Code Quick program. It really is an easy way to learn and quickly remember the code. There are countless gimmicks and "5 Minute Ab"-type programs that try to rush you through the learning process as fast as humanly possible, but few are ever successful. You just can't hurry the learning process. The downside of the CodeQuick method is not immediately known until you're trying to copy signals that are faster and faster. Once you hit about 10wpm, the CodeQuick lessons that you've used as a crutch finally become a hindrance and make copying code faster more difficult. The big plus is how quickly you'll learn the code in relatively enjoyable lessons compared to other methods.
Another alternative to learning the code is one of dozens of Koch method trainers. The Koch method, and most others, ram the code into your head seemingly through brute force.

Morse Code: A Brief History
radio : by Tommy - October 18th 2010, 10:12PM
radio
Most people know the important life-saving phrase Di-di-dit da-da-dah di-di-dit (SOS), but that's about it when it comes to Morse Code. Many people know that Morse Code was named after its inventor, Samuel Morse but not much more. Fewer people know that the use of Morse Code still persists (unless, of course, you know someone that uses it on a semi-regular basis!).

Morse Code is the oldest form of telecommunication still in use. It got its start when the legendary Samuel F. B. Morse, an artist by trade, began to experiment with methods to communicate via the relatively new field of electricity. Morse's system of communication was not the first form of telegraphy, nor was his invention the only electric telegraph. But he did invent a language of dits and dahs that, by way of a few revisions, remains in use to this day. (The history of the telegraph, interesting in its own right, is beyond the scope of this outline.)

Ham radio operators are perhaps the most notorious users of this antiquated form of communication, but not the only users. Navy signalmen use Morse Code when manning the Signal Lamp and aviators make use of the Code as a way of identifying directional beacons.

Morse Code has undergone few revisions since its inception. Morse's original code was a bit cumbersome, but the idea was there and several letters have remained unchanged. Morse originally planned the letters to leave imprints on a printed tape, but over time the code was learned by operators and the incoming signal was able to be decoded by ear rather than on paper. In order to speed up transmission, Morse gave the most frequently used letters the shortest signals. (E gets a single ‘dit’ and T gets a single ‘dah’) Identifying the most frequently used letters, Morse counted letters in a copy of the newspaper.
