Good suggestions. I hope that this site starts to be more proactive with members.
In addition I suggest:-
5. The maximum 30kHz limit is a hardware limited but the lower limit of 1kHz could be even lower, though i realise this affects overall span observed. Then again in the application of observing modulation on a carrier, you are looking at signals close-in. I suggest including 300Hz and 100Hz as lower bandwidth options so that Bessel functions (carrier drop out points) can be observed as part of calibration checks for FM deviation with 1kHz mod source.
That way you can resolve and observe the carrier from the FM side bands.

Can you please provide a response to this request. It does not require a hardware change but it does affect device functionality and ease of use by the end user.
The presence of the output signal in AF or RF generator modes is not currently indicated sufficiently.
This could be fixed by a programing change to indicate the output is of by:-
1/ Flashing the output level setting OR
2/ Changing the level setting colour to red when it is not on.
This issue has been noted in feedback from many users of the various KC901 models.
If there is a reason why this simple software changes proposed at 1 or 2 cannot be made then please advise that.
