Hi Peter, thanks for your explanation of why it is hard to decipher human created morse code transmissions.
I found this "Morse code discriminator" in Ron Wiesen's member upload area. (http://www.club100.org/memfiles/index.php?direction=0&order=&directory=Ron%20Wiesen/Morse%20code%20Discriminator%20for%20Model%2010x&;) So this is only for weather balloon data transmission as he describes in one of the files? I don't know if Ron is still active on this mailing list? If you are, Ron, maybe you can help me a bit with this?
