[Elecraft] K3 AM vs FM filter

[Björn Mohr]

Hi gang,

As I understand it the FM filter would be best for AM BC with its wider
bandwidth. Not perfect, but certainly better than the "AM filter" that I
guess is aimed towards voice AM communications.

Has anyone tested the FM filter for AM broadcast reception? If so, what is
your comments and advice? Is it suitable for this purpose, or are there a
better solutions out there.

Regarding AM voice operation, I do one AM contest per year. I guess it would
be possible to use the FM filter also for AM TX and restrict the bandwidth
on a DSP/audio level, or is this a bad idea?
