PICAXE-28X2 ELECTRONIC SUPER KEYER

 

(AND TRAINER WITH 3 RELAYS)

 

This project uses 3 high speed reed relays. One relay keys the HF radio, another relay keys the VHF/UHF radio and the third relay goes to the computer serial port to use the paddle key for a program called CW communicator or CW Com. CW Com is a CW over IP program and is pretty cool. Hence the requirement for an electronic keyer with 3 output relays.

Never unplug and reconnect the key to a different radio ever again!
