![]() ![]() ![]() All the spacing was locked to ideal morse code at the speed it averaged from receive. It took what it got timing wise from the sender and used that to transmit back. The program would do a guess to supply a missing dot or dash to generate a character based on what it heard and looking up valid Morse code characters. Those who used iambic keyers, vibroplexes and such it would do real well in getting a proper decode. It even calculated the approximate speed in WPM and displayed it. ![]() The MFJ-464 uses the same decoder as the MFJ-461.In addition to the decoder, the MFJ-464 offers a Morse keyer. I used a subroutine that checked once a second to see when the characters were actually arriving and the length of dots, dashes and spaces the operator was sending adjusting the sample timing to fit. Morse decoder and keyer in a compact housing. It started out at 8 WPM using the weights suggested for sending proper CW. Click to expand.Way back in the dark ages of 8bit I wrote a 6502 machine language cw decoder program on the Atari. The CW Decoder is an excellent tool for viewing and displaying continuous wave data from multiple sources.
