My decoder is a combination of a number of articles and open-source programs I have reviewed along with my decoder I wrote back in 1981 in assembler. Then open up a wavefile then press Play button. The data file directory has a sample morse.txt file you can edit to create your own.Īt first, choose the desired CW speed using the slider and deselect Auto Speed. I also created a program named cwgen.exe which will allow you to take a text file and convert to a wave file containing the Morse Code. I deposited a few sample wave files including an ARRL bulletin I recorded.

The program will install at \Program Files\CwDecoder and an icon named CwDecoder will be placed on the Desktop.

If you have a Windows 10 64-bit machine and would like to try out my very early release, the installer is here:

For testing purposes, I removed the CwDecoder portion and created a Windows 10 standalone application while I debug the CW decoder algorithms.
#Morse decoder for sdr software#
I have been working on adding a CwDecoder to my SDR software which also supports interfacing with the mcHF SDR via IQ and CAT commands. Currently I use both internal decoder and PC software for decoding and keyboard for sending. I 'm also using PC software (CW get) and found it very useful for receiving, but I can't seem to make it send, it is either keying with no sidetone or generating sidetone via USB soundcard but no keying.

This way I have already learned few letters / usual phrases that I recognize wit my own ear/brain, which I think it is a big step forward into learning CW. I managed to have several QSO's and I don't know CW :) For sending I use a USB keyboard. Very precise tuning required (use SNAP!) and if the signal is good sometimes it decodes well. In settings I keep the level for decoder at 32000, AGC for decoding ON and Goertzel block size at 8000 or so (I don't have the mcHF in front of me now). I use sidetone 750 Hz, BW 550-900, AGC Long and I play with AGC level to get the best level for the red LED to light exactly with the received tone. Hi, I have also fiddle alot with CW decoding and lately I get good decoding only in certain conditions, I think is more depending of the quality of the signal and also the quality of keying at the other end.
