Michael,
I think the rolloff is not much (in support of those who want ESSB
operation. Much of the rolloff depends on your microphone.
Jim Brown K9YC has long advocated reducing the TX EQ below 500 Hz or so
in order to increase your effective communications power. An
improvement of 3 dB or more can be had by reducing the low frequency
audio since those low frequencies take a lot of the total power and add
little to communications effectiveness.
73 and Merry Christmas,
Don W3FPR
