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. decoding it Unitrunker understands the following control channel trunking protocols. 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. software allows Unitrunker to control SDR-Console V2 First dongle was. 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.
