EZKeyer II
Text size too large or small? Use your Ctrl key and scroll wheel to adjust it.
This Kit Has Been Retired
Building on the very popular EZKeyer, this new and very capable Morse Code keyer has
some additional features -
a beautiful blue, easy building, enclosure, new PIC microcontroller, larger message memories, additional commands, new printed circuit board layout,
and large push button switches. Gone are the small push buttons that were mounted with super glue and
connected to the circuit board with wires.
Additionally, all connectors and switches are board mounted, making the keyer completely self contained
on the board. No external parts or wires are required (excepting battery leads).
It has many of the features of a high end keyer while remaining very user friendly.
The PIC chips have been programmed by Craig Johnson, AAØZZ, of PIC-EL fame, and the
commands are entered directly with the paddles rather than scrolling
through menus.
With overall dimensions of only 4" x 2.5" x 1.38", this EZ-to-build small
footprint project will have large impact on your operating capabilities, whether
in the shack or in the field.
First time builders please note: This kit is a very easy kit to build.
All parts are through hole parts and are wide spaced on the board making
installation easy. All connectors and switches are board mounted which eliminates point
to point wiring, and after all the parts are installed it's ready to try out.
The kit includes all the components required to build the keyer -
switches, connectors, speaker, programmed PIC, components,
AND the enclosure.
