distorted FM audio

[Chris Meagher-4]

I have just started using 2 metres FM on my K3 #685.
The receive audio is rough and distorted, it sounds as if its being clipped.

The FM Inrad filter is .in slot 1 and FL1 is showing.

By comparison, my Yaesu FT3000 and FT817 are qute undistorted on the same
signals
K3 SSB audio is fine.
Can anyone assist as it is not pleasant to listen to.

On your filter setup in the K3 utility, set Freq Offset to zero to start.
Set bandwidth to 13, and check "FM Enable".

Also make sure that the FM filter really IS in slot 1, and that it is
properly seated.

Hi Chris,

not changable, it's by design. :-( The "clipping" sound is due to the NF
stage which limits at about 4 kHz. The KX3 is much much better in that
respect.
