OSK  The open Source 4 channel Memory Keyer'

This is the full Kit version supplied with case and pre punched front and back panels.

The OSK-1 Keyer is a feature rich low cost memory Keyer, offering features that you would expect from keyer’s much more expensive. The CW training mode is excellent and worth building the keyer just for this feature.

The Keyer is built around a small but powerful microcontroller. The code for the chip is open source from Jan DK3LJ who developed the original program, later modified by Jack AL4SV and then further modified by Don WD9DMP who made some changes that polished Jan's code even more .

The finial product rivals professional keyer’s costing many times the price.

This open source code is now installed onto a Attiny85 chip, It fits on a small PCB and can be built in less than an hour. Full kit or pre-built unit use a different PCB
