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, Don W3FPR ----- Original Message ----- > I recently built a KSB2 with the now standard 2.3Khz filter configuration.
