MSK is FSK with shift (as understood by hams) equal to half the baud rate. So
45.45 baud with 22.725 shift would be approximately MSK. if you've used 45.45
baud with 23 Hz shift you were close enough to MSK, especially with narrow band
filtering on TX and RX.
When done correctly, MSK is phase continuous and has nice spectral response.
With Baudot 7.5 bit coding like we use, I'm not so sure. That 1.5 bit long stop
bit can really screw things up.
I think that Chen covered this recently.

That's a new one on me. I googled it and found there is a lot of info on it.
Are hams using it? What software?
