I would like to suggest the following as a possible future improvement to the
K3's S-meters scale..
We would have 2 switchable scales, the current scale and an alternate meter
scale that uses the current S9+60db scale range to indicate signals only
up to the S9 level. This would give a much wider dynamic range and improved
s-meter resolution for signals up to S9.
The current 20 bars would roughly give an indication of 3db per bar. If the
signal shoots over S9 a flashing + sign would flash or the S-meter would
automatically fallback to the standard K3 S-meter scale.
Another possibility would be to switch in the attenuator automatically to
keep the signal in the improved scales range if the signal is greater than S9.
This feature could be applied only to the higher bands or any number of
bands.
This feature might not be very useful in places like Europe where 20db over
S9 signals are routine on every band, however on quiet bands it could prove to
be useful.
I currently use a VU meter in a similar manner with the AGC off. This setup
was first suggested by Wayne Overbeck N6NB in his many QST articles on antenna
gain measurement.
