N3ZN Keys


K7QO on his website wrote an article about a beautiful paddle he had purchased called the ZN-4A from N3ZN Keys. If you are interested in paddles at all, take a look at Tony’s web site and enjoy the incredible workmanship in the paddles. What great looking paddles!

555 Code Oscillator


This is the circuit diagram I use for a code oscillator used to teach adults at Community Living here in St Thomas the morse code. Along with Floyd VE3ONF and Terry VE3TEH, we have been practicing Morse Code there for a few years. They seem to enjoy it – none of them will ever be able to copy code faster than one word per each 5 minutes, if that, but they enjoy meeting with us and playing with the code once a week.

QST Quickstats

from QST January 2011 p. 128
What is your comfortable CW receiving speed?

None – I don’t operate CW – 27%
1 to 5 wpm – 11%
6 to 10 wpm – 15%
11 to 20 wpm – 25%
21 to 25 wpm – 14%
26 to 30 wpm – 5%
31 wpm or highr – 3%

Interesting, eh? Not as many higher speed operators as I thought there might be.

Keys and Paddles

This is the type of key most hams would start out using. The action of the key is up and down, when down, the contact is made and the transmitter turns on and transmits a CW signal. Your wrist (fist) gets tired fairly quickly when you use this key so other more user friendly devices were created to send the dots and dashes.

I find this device called a keyer paddle much easier to use once you are used to it. Pressing the left side will send dots and pressing the right side will send dashes. A keyer is an electronic device which is in between the keyer paddle as shown and your transmitter and produces a dot when you press the left side of the paddle and a dash when you press the right side of the paddle. One advantage of the keyer paddle is that the keyer will produce either dots or dashes as long as you press the left/right side of the paddle. This is a commercial keyer paddle from American Morse, a small portable keyer paddle. This keyer paddle has been designed for use in portable operations, it is small and light. I bought one a couple of years ago at Dayton.

If you want to save money, then you can build your own keyer paddles out of common paperclips. Here is a link to an article giving you more information about paperclip keyer paddles.

Morse Code

The Morse Code is no longer a requirement for the Canadian amateur radio license. Even though this is the case, many hams are still learning and using the morse code. The chart below gives you the letters, numbers and special characters in morse code. The second chart can be used to help learn the code. Enjoy.
