[Elecraft] WHY NOT 700HZ FILTER FOR K3/K3S?

[donovanf at starpower.net]

Several small productions runs 700 Hz crystal filters were manufactured 
for the K3 several years ago. Unfortunately they're rarely offered 
for sale on the used market.

It is a better thing to have a roofing filter, i wouldnt like to use only the 
dsp with the 2700 ssb filter. 
I have the 500hz 5 pole filter (and the 200hz 6 pole), but I find that 
sometime I have a nicer audio tone with a wider filtering. 
1000hz is too wide for me, sure it is good with rtty, but for cw with our 
noisy and crowded band is too much. 
So I think that a 700 hz Bessel filter, or a better (wide at the base) 
gaussian 600hz sure would have a better audio cw in reception.
