Deluxe CW Keyer

This keyer is build with the CMOS SUPER KEYER II  kit from KC0Q/N0II
The keyer normally has only 4 buttons for operation ,and all special functions must be accessed by pushing 2 or more buttons at the same time.You always should have the manual very close at reach,or have a good memory to remember all combinations.
With the addition of some extra hardware it is possible to enhance the keyer a lot,by just adding some extra push buttons and some diodes.

This is the original diagram of the CMOS KEYER

This is the expansion made,everything can be build on a piece of breadboard

.

As i know ,the same principle can be used on the CMOS SUPER KEYER III
