Homebrew Keyer
 

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,

Not a schematic, but how about a kit?

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!

I built the N0XAS PIC keyer kit. It works well.

Jim,

I have a PK-3 Keyer I got from Jackon Harbor Press as kit to use in a 10 Meter Beacon. But I ended up using a KID Beacon ID controller for the beacon instead. The PK-3 is a iambic keyer with 2 memories plus callsign memory, side-tone, auto CQ, beacon, A/B modes, 5-39 WPM, low current, Tick compatable. It uses a 12CE674 PIC keyer chip. I built and wired the PC board but never installed the PIC chip. I paid $19.95 plus shipping for it. I've never used it and am not going to. If you are interested in it I'll ship to you for $15.00. That's $10 for the keyer and $5 to cover the cost of shipping USPS Priority Mail.
