[Elecraft] 6 Khz filter question

[Joe Subich, W4TV]

The DSP is limited to a maximum bandwidth of 4000 Hz and a highest
"high cut" frequency of 4200 Hz.  However, that 4 KHz (200-4200 Hz)
is more than adequate to cover both JT65 and JT9 sections of the
various digital activity (e.g., dial = 14.076 gives 14.0762-14.080
with no issues).

> Good afternoon all, I have for some time now had the 6 Khz filter installed in my K3. I was just recently on JT-65 in Data A mode and wanted to use the 6Khz filter. I was only able to open the width to 4 Khz using the width knob? I wanted to open it up to 6 khz so I could receive both JT65 and JT9 signals.
