Text- and Graphic Display for the morse signs. Features: Morse Code Decoding 0.4 to 60 WpM. Ham Radio operators use MRP40 to overcome weak DX conditions. All the spacing was locked to ideal morse code at the speed it averaged from receive. MRP40 is an amateur radio software program to receive morse code via soundcard, it allows to transmit morse code from the keyboard. It took what it got timing wise from the sender and used that to transmit back. MRP40 is a powerful and highly-effective ham radio software program that decodes received CW audio that has been fed to a computers sound card. No additional hardware required - you need only receiver and computer with a sound card. It can work as narrow-band sound DSP-filter also. 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. A program to decode morse code (CW) via sound card to text. On the other hand, CW Get has a new, improved version, and all previous versions have always worked with no issues. Previous tech support was poor to none existent. From first having access violations to now NO boot. Those who used iambic keyers, vibroplexes and such it would do real well in getting a proper decode. Since Window's latest update 22H2, MPR40 will no longer work at all. It even calculated the approximate speed in WPM and displayed it. Here is a link to for the MRP40 and you can have a free trial. 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. MRP40 Morse Code CW Decoder with Icom 7300 Settings. 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.
