Hm, maybe I can convert the rtlsdr source I have to
handle extio files. That might keep me off the street a few days.
OTOH it would be a more fun challenge to skip the extra dll and
include that code into a sourcexxx.dll. Then you'll be able to
Simonize (ouch) work I kludge into something in your style and
more trouble free.

Tensorflow is an excellent system for
this sort of thing. The author of that article used
random words to train the model, but if he used more
traditional ham conversations it would help a lot, at
least for amatuer use including typical abbreviations
and Q signs so they would be better represented and not
read as errors by the model. The other thing that would
be useful would be to send a bunch of known CW text
from an automated keyer and pick up the audio from a
remote SDR, so the model would include fading and other
non-linear impairments that come from real HF paths that
hams deal with all the time. The cherry on top would be
to have hams send a set of known text with keyer, bug or
straight key and capture that over the HF signal path as
well.
If the ML model is trained well, I
would not be at all surprised if it could decode CW
much better than the best human. I have been
surprised as to how amazing the pattern recognition
capabilities of well trained models are. The key is
all in the training.

There are a huge number of
new tools for using AI today that leverage
modern compute infrastructure. Unfortunately,
many of the public ML tools out there are
optimized for visual image processing, as
opposed to audio or RF SIGINT style uses. But a
number of efforts exist to convert audio or RF
to an image, and then use the image tools to do
the training and generate a model for decoding.
While the training is computationally expensive,
once the model is built, it can be pretty
efficient to run.
There was another one that
used ML, GIMP and RTL-SDR's to do signal
identification using images again, but I can't
seem to find it now.

You will do a great

the missing r and n.
The brain is the best noisefilter ever. A computer can come
close. But when the conditions are at the noise border, the
brain can fill in missing signs.
Decoding BELOW the noiseborder?? yes thats a thing a computer
can do (but not with a hand keyed cw signal) ... see WSPR or ft4

The other station is "smearing signs" a bit?!? No way to decode

Hi All, Over here it’s 2022 so a very happy new year to you all. I’ve updated the current V3.1 beta and am now spending January designing a CW Decoder harness which I hope will help me develop a good CW Decoder, so for January and possibly February you’ll not be hearing much from me 😊 .

Hi Simon
If you are
writing the program will it not precisely reflect the ability of your own brain….
Nowt to do
with the computer.
It will definitely
be a jolly good program.

A working cw tx would be nice.. Now most sdr users use a software like morse keyer connected to console and transmitting in ssb A direct keying in console would be needed Dg9bfc sigi Ps HNY SIMON

John
Happy New Year to Simon and everybody else, hope everybody has a great new year. No doubt we'll all get some new SDR's and probably some new antennes and some more of everything else that goes with this great hobby of Amateur Radio, Short Wave Listening and anything else that we might do with our radios. Hope everybody has a great new year, Very Best Wishes and Very Best Regards to All on the list or off the list.
Happy New Year and I hope 2022 is going to be great for everyone. John. Good luck with the CW decoder Simon, Sorry you don't need luck Simon with all of the fantastic software you write. Just a wee bit of time to think and you will have it done in no time. Very Best Wishes and Very Best Regards to all and I hope everybody has a brilliant 2022. Happy New Year to Everybody John.
