Anyone know of a person who went into the 7300 firmware to enable/Hack it to decode CW? RTTY sure does work good. Thanks in advance.

Rtty is easy to decode.  It is machine sent.  One RTTY signal sounds pretty much like another RTTY signal for the most part.  Machine sent CW can be decoded by computer.  Human sent CW"?  well not so much.  depends on the human sending it. And some decoders are way better than others, but in general don't expect much from any computer decoding human sent CW.  I can't decode a lot of human sent CW even if it is in my speed range.  Some people should stick to phone or digital, either that or practice a bunch before enabling the break in function. I had 2 CW qso's yesterday.  Both were sent by straight key, one was a joy to copy, and the other was a major chore to copy due to me not always able to decide if I heard a dit or a dah.  How well do you think a machine will do?

If you are tuned to the ARRL cw messages sent at different times during the day or night  a cw decoding system does work very well but its machine sent. I have at times to brush up on my copy use the decode feature in the Yaesu FTDX3000 to copy the ARRL bulletin and use it as a check on what I have copied on paper not looking at the screen and that feature does work but it really depends on the fist or keyer hand of the sender on anything else on the band but it has to be tuned just right plus the speed control set proper along with decent strength and no qrm. RTTY is far easier for any of these rigs which have a decode feature, most times its dead nut on, CW not so much.
