No. I have the 13KHz FM filter but the receive bandwidth is still limited to
4KHz.
I can appreciate that for use with PSK

As you indicate you're a CW man, I'd opt for at least the 400 Hz 8-pole

One excellent long-term solution was proposed by James, K2QI. I have since

are far better in fit, finish, and usability than Elecraft's stock knob set.
But, they are also relatively expensive.

Sorry, I was confusing the two, you did say *Sideband* 9.001 after all.
So in the case where the IF is 5 MHz and the VFO is 9 MHz, we have:

VFO 9.000 - 5.000 = 4.000 MHz
VFO 9.000 - Sideband 5.001 = 3.999 MHz
