What is electronic keyer?

Keyer The term “keyer” is generally used to refer to an “electronic keyer,” which is a device that will generate dots or dashes depending on which of the two input switches is closed. Usually a device called a “paddle” is used for input switching (sending).

What is a keyer used for?

A keyer is a device for signaling by hand, by way of pressing one or more switches. Modern keyers typically have a large number of switches but not as many as a full-size keyboard; typically between four and fifty.

What is Morse code keyer?

Notes. A keyer (combined with a “paddle”) makes sending Morse code easier than the traditional “straight key” which most people would imagine is used. The keyer defaults to “iambic A” mode which sends alternating dits and dahs while both keys are pressed.

Is keyer a valid Scrabble word?

What is keyer music?

Why is Morse Code illegal?

Also, for US amateur radio operators we cannot legally use American Morse on the air. That’s because the FCC has defined the CW mode as using International Code only. There is no legal mode that can use American Morse on the air because of that definition.

How do you make a simple CW touch keyer?

Simple CW Touch Keyer Circuits. Here are some simple CW touch keyer circuits for making your own CW touch paddle key. The first circuit in Figure 1 is very simple, just consisting of two NPN transistors! It works by using the 50Hz mains voltage that is induced into your body by nearby mains wiring to provide a small base current which switches…

What MOSFET do I need to make a CW touch keyer?

A very cheap logic level MOSFET for this project is the 2N7000, which has an on resistance of 5.3Ω but you can buy 10 for around £1. OK, so how do we make a CW touch keyer without an annoying wrist strap?

What is the difference between mechanical key and electronic key?

The key had a paddles and when moved to the left made contact for the dashes, and when moved to the right, it set a vibrating arm in motion to create the dots. Electronic keyer: The electronic keyer is an electronic development of the mechanical key.

How does the iambic keyer system work?

The iambic keyer system uses two paddles side by side to provide the “iambic” mode. Here if the left paddle is pushed to the right, a series of dots is made. If the right paddle is pushed to the left, a series of dashes is made. If the two are squeezed together dots and dashes are interspersed.
