Hi Mike!

I agree with you. I also like the more "full" audio and I really would hate
to see the K3 restricted in hardware or software. Adding a SSB TX bandwidth
menu for adjusting this to each users preferences would be fine:

2400 Hz : 300 - 2700 Hz
2600 Hz : 200 - 2800 Hz (default ?)
2800 Hz : 200 - 3000 Hz
3000 Hz : 100 - 3100 Hz (requires 6kHz IF-filter)
3500 Hz : 70 - 3570 Hz (requires 6kHz IF-filter)
4000 Hz : 50 - 4050 Hz (requires 6kHz IF-filter)

One can also use a microphone with low cut (the Kenwood MC-90 is great and
fits directly on the K3 without re-soldering the 8-pin connector). This one
has a low cut with 2 positions, and it has a great audio response for SSB.
It is a 250 ohm dynamic microphone with two replaceable microphone heads.

For ragchew on a quiet band it is nice to have some more low end and
bandwidth.

Best regards
