   Dan Trudgian M0TGN has been blogging recently about his latest project, an Arduino Morse decoder

He wanted to create a project that would “inspire” young electronically minded students that might have an interest in radio – (i.e the Morse code) some coding experience and some construction / electronic interest..

He is using a very simple single tone detector interface between his radio and the Arduino microcontroller board.

Single tone detector circuits first became popular in the UK around 1980 when they were used for RTTY as well as CW. The UK produced IGADUMA terminal unit was one such example. The circuit Dan is using is based on one published in QST magazine and only needs a few components.
