|MRP40 decoding some Morse|
MRP40's decoder is less laggy than CW Skimmer's - text appeared sooner after it was sent. I also found MRP40's AFC useful in locking on to signals. It could track drifting stations and would adjust itself precisely to the signal if you didn't click exactly on the trace. CW Skimmer seemed more fussy and didn't decode a signal unless you got it spot-on. This is perhaps understandable given that Skimmer is intended to be able to distinguish between multiple signals in a pile-up.
CW Skimmer is the better program if you want to decode all the calls in a swathe of spectrum and if you want to link to your logging program so as to highlight new countries or prefixes and mark stations you've previously worked. That is, after all, what it has been designed to do. But as a morse decoder pure and simple MRP40 is still the winner in my book.
