[Elecraft] 2.3kHz KSB2 feedback

[Don Wilhelm]

Folks,

I didn't know that the 2.2 (or 2.3) kHz SSB filter had become the
'standard', but it does get my vote.  I have long advocated the KI6WX 2.2
kHz filter bandwidth as my choice for a great compromise between 'punch' for
QRP operation and good SSB fidelity.  It does offer a flatter passband than
the original 2.0 kHz SSB filter.  To my mind, the 2.5 kHz bandwidth is a bit
too wide, but many folks favor it for the increase in fidelity.

I do recall there was a time when the Collins 1.8 kHz  mechanical filter was
considered the ultimate for communications effectiveness - at least in the
receive part of things - my how times and values have changed!!!

73,
