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. After connecting your Mac to your radio (see our interfacing notes for details on this). PointClickCare is the 1 cloud-based healthcare software provider helping long-term and post-acute care (LTPAC) providers navigate the new realities of. Those who used iambic keyers, vibroplexes and such it would do real well in getting a proper decode. Using MultiMode, you can send and receive morse code with your Macintosh. The sent CW timing must also be accurate (e.g. The signal to be copied must be fairly strong (at normal CW speeds, the human ear can decode CW at lower signal-to-noise ratios than software can) and clear of QRM and QRN (heavy QRM or QRN can render the CW undecodeable). It even calculated the approximate speed in WPM and displayed it. Software decoding of CW (Morse code) has its limitations. 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. 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.
