Look at? your KSB2 board.? If CB and CN positions are populated, you
have the narrow 2.1 khz filter width.
On my Rev-A K2, I've changed crystals, changed the filter capacitors for
2.6kHz, and made the drive modifications from KI6WX (I'm driving
transverters on 10m).
People complain that the audio doesn't sound right, and the Spectrogram
grapth is far from flat. I'm OK with RX audio but people complain about
my TX audio.
Is there any way to make the passband flatter, or to make the audio
"fuller"?
I am aware that TX and RX can use different filters and adjusted for
that. I just worry about the TX reports I am getting.
