[Elecraft] K3 Crystal Filters and Dynamic Range - D.R. impact and my basic recommendations

[Bill Tippett]

WA6HHQ:
 >Notes:
Since we  also transmit through this (2.7 kHz) filter...

         Will it be possible to transmit CW through
a narrower filter than the 2.7 kHz to even further
minimize transmitted key clicks and phase noise?
If so, how low in BW could we go before causing
problems?  1 kHz, 500 Hz or even lower?
