One man was recommend to me a SkySwepper PRO for the morse decoding.
That software use a neuronet algorithm for the morse decoding.
He is mistaken not so often then CWGet or other soft with any algorithm.
But I don't test it personally.

CWGet is need 1 chapter for synchronize  a decode process.
If your have a QSB signal decoder re-synchronize each time when the level of the signal up-n-down across the level border into program and decoding process will be bad. I use a GWGet so often for decode a NDB, CW on DX'ng, trying to use for decode a CW from HAM-SAT. You need a 'crystal' CW signal w/o QRM and QSB then the decode process will be good.

It is virtually impossible for a machine to read poor morse because
when
the
elements are split up you get a different character to that intended.

What about the 700 plus that you missed.
