You can select the FFT size in the form: a small FFT size will give a small time resolution (good for fast Morse code) and a large FFT size will give a small frequency resolution (good for eliminating background noise) but you can't have both at once. Last updated Tuesday … The frequency resolution is Hz (sampling rate / FFT size). If you've arrived here then you might prefer the newer streamlined version which adapts to the speed and frequency of the Morse code. This is because, relative to the speed of the Morse code, the measurements are quite infrequent. Use the "Apply" button to change the parameters to those selected in the table.

Phillips, 2015-2020 The decoder does some further signal processing by asuming that if an "on" or "off" element was only 1 measurement long then it was probably due to noise and so the previous timed element is just extended.

"Inspector Morse" is the start of a British TV drama where "MORSE" was spelt out in very approximate Morse code (the decoder can't manage it). We have over 10 years experience of DCC sound and have been lucky enough to fit sound to models owned by some of the leading names in the industry such as Legomanbiffo.
