John,
Compression on AM is not currently permitted because the same algorithm
used for SSB creates distortion in AM - I believe Lyle has promised to
develop a new AM compression algorithm, but I don't know when.
I have no clue about your FM problems - what deviation do you have set?
Check the FM DEV setting in the menu - the default is 5.0 kHz.

Merry Christmas everybody,
I've just updated my firmware to 2.67.
I now have no compressor available on AM and the audio sounds very
thin and low - very similar to that on FM.
The modulation appears to decrease the carrier power. This second
problem has been an issue for some months.
The FM has always sounded dreadful. Is anyone else using their K3 in
anger on either of these modes? If so are you noticing the same things?
Altering the TX eq does not solve the problem.
By comparison my IC706mk2 in AM mode gives lots of upward modulation
with compression, which is required under noisy conditions. The same
radio on FM narrow gives very good audio as well.
Having done a super job with SSB and CW, I'm hoping we can get a
really top quality AM and FM transmit as well.
Thanks in anticipation
