[Elecraft] K3: FM filter bandwidth in other modes

[Stephen Prior]

I have just realised my mistake.  I can find no reference to it in the
manual but in searching the archives (again) I found a posting which
mentioned the 4.2kHz (AFAIR) bandwidth limit imposed by the DSP.  So, it
would seem that things are working as they should- I was confused by the
filter setup which apparently allows the setting of bandwidths higher than
this on all modes.

Have I got this right?
