[Elecraft] 2.1 kHz filter - K3

[Philippe Trottet]

In addition to the 2.8 Khz,  I'm using the 1.8Khz (starting 2.1) , and also the 1khz (starting 1.6khz) used both in ssb & cw. 
Sure with some little alteration of the voice but it is really a must in severe qrm environment as mine (no directional antenna and a lot  of pirates, fishermens etc....very active on that part of the world.)
One example, on the low part of 20m, specifically on 14.122,3 usb we have fishermens, Tamoul language, every day and we have the French speaking dx window for FO, FK.... on 14.122. 
Even those illegal user are sometimes 59+ I'm able to pursue qso's at a 300hz difference that never happens with my previous rigs. As I say voice is alterated but readible when playing with the FC and width ~1.5Khz even less.
In that case I'm just increasing my power because I'm sure those fishermens are using marine rigs and do not have the selectivity of the Elecraft's... and they qsy most of time.

I have the 2.8 kHz filter in the main receiver and want to supplement that 
with either the 2.1 kHz or 1.8 kHz filter.  A friend who has the 1.8 thought 
is was too narrow.  What are you guys using?  Anyone have all three?
