Certainly not. I'm not sure whether it is recovery time or latency, but 
in full break-in mode, you hear nothing between the dits above something 
like 10 wpm. (Even with AGC off.) With other non-DSP receivers, one can 
hear between the dits up to at least 30 wpm with fast AGC. Perhaps it's 
just the price we pay for the power of DSP.

Many years ago, when there were sunspots, I recall hearing multiple 
echos on 15 meters. I timed them, and the time interval was about 133 
ms, just about the time it takes radio waves to circumnavigate the 
earth. I heard them go around at least twice, and that was receiving off 
the back of a beam. Talk about long path! That would not have been 
possible with a DSP receiver.
