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=20
level of the signal up-n-down across the level border into program and=20
decoding process will be bad.
I use a GWGet so often for decode a NDB, CW on DX'ng, trying to use for=20
decode a CW from HAM-SAT.
You need a 'crystal' CW signal w/o QRM and QSB then the decode process=20
will be good.
