After spending four years in Singapore I am back in my home state of Michigan and slooowly putting a HAM shack together. I am in need of a keyer to go along with the new magnetic iambic key I acquired. It looks like Idiom Press is defunct but I only found this out after I had ordered the partial kit equivalent of the CMOS-5 Keyer. My question of all of you home brewers is: Do you know of any equivalent Morse Code keyers, either commercial, or preferably, of a home made type? Any preferred circuits?

My favorite homebrew keyer these days is one based on the Arduino Nano and software written by K3NG: http://blog.radioartisan.com/arduino-cw-keyer/.  It is a very simple circuit to build and offers a great introduction to Arduino development.  If you want something even more like a kit, there is one called the Nanokeyer based on the same software: http://nanokeyer.wordpress.com/ that comes with components and a PCB (you provide the Arduino).

Two options come to mind in response to your question:

1. Kanga US (www.kangaus.com) offers the TICK1 keyer, based on a pre-programmed microprocessor.

2. If you wish to "roll your own", there's always the original circuit from Solid State Design For the Radio Amateur (Hayward/Demaw), using three 555 timer IC's.  Do a google search on "555 w7zoi keyer" and the schematic will pop up at several different web sites.

Take a look at the site of K1EL:


You sure will find what you need at reasonable cost!

My thanks to all who responded on this reflector and off the reflector. Now I have to wade through the information and pick something I like.
