[Elecraft] KSYN3A Question & NR audio canceling

[ARRL - N6MQL]

Wayne,

The new KSYN3A is supposed to have the new wonderful T/R speed making CW 
QSK sound like the old KSYN3 with the QRQ selected to on (for the most 
part).  This leaves me with the question... Since the QRQ function is 
still available when you have the new KSYN3A boards installed, what does 
it do?  Is there any change between having the new Sync boards in and 
turning on or off the QRQ function on the K3?  Or is it essentially 
making no difference other than killing your RIT and Split functions? 
Perhaps my ears are lying to me, but it still seems that if I use the 
QRQ setting the T/R switching seems much smoother when moving fast. 
Perhaps this is reson for using the "New QSK" mode in the CW WGHT menu 
setting?

Also, is there anything that can be done about the way the audio is 
completely canceled out when you have a loud noise floor and you're 
using the NR and then move the Width knob?  If I'm in the middle of a 
QSO with someone (in receive) and I have my NR on (because the noise 
floor is loud) and then I decide to narrow the filter down onto the 
person I'm listening to I loose copy because the audio drops out as I'm 
moving my filter settings.  If this were a case of the NR having to 
rebuild, I would almost rather have it turn itself off as the filter 
bandwidth is moving then rebuild when you've stopped turning the knob.
