Nowadays, most keyers are nothing more than a micrcontroller, usually a PIC,
a battery, a couple of jacks, and some sort of interface, usually a
pushbutton. There must be a hundred designs out there, but they all boil
down to the same thing. It used to be that the PIC was relatively expensive
($6 or $7) but nowadays, a PIC with more than enough juice for non-memory
keyer is $1.01 at Newark. For a memory keyer, you might have to get close
to $2. Still way less than the shipping.

Far Circuits has a PC board, K1EL sells programmed chips. Google is your
friend!

Does anyone have a schematic for a nice homebrew keyer that can be made
for a reasonable price. I would like to make my own.
Thanks,
