SIMPLE CW KEY
This kit includes the assembled and tested CW Keyer PCB and some other parts you can see on the pics.
This CW Keyer has a memory of last pushed dot or dash so it helps to send the letters very clear and correct.
It works fine within 3 to 15 VDC voltage so you can even hook it up to the small 3 V battery and use it in portable operation saving energy of your radio.
To get this KIT worked you should do the simple wire connections. I am including the circuit diagram and diagram of the connection. It is really very simple. Only thing you have to do is to find a suitable enclosure of your choice and mount the PCB and connectors there.
