It allowed me to contact more than three thousand stations by telegraph without fail

Arduino uno compatible board, it doesn’t really matter what is the board that you are using, as long as it has enough gpio and at least 1 uart to work with

Arduino vector graphic antenna analyser a project from DG7EAO

The reference hardware design ad prototype i built is using an arduino uno and has 100 watt capability

Setting up the arduino due running as an sdr receiver

This is an open source arduino based cw

This arduino library which i have created will allow you to control various functions of your radio via an arduino micro-controller through the use of “computer aided transceiver cat functio

Using a paddle to operate in morse code is very convenient, but paddles don't create dots and dashes on their own, so you need some electronics, called a keyer

My primary interest was for vhf/uhf/shf, i have foreseen positions for 6m, 4m, 2m, 70 cm, 23cm and 13cm bands - but you can use the arduino readout on hf as well
