[Elecraft] K3 feature request query?

Hi Sam,

I often thought about this as well.

Since the noisefloor is generally much higher on the lower bands, it would
be nice if AGC threshold or RX IF gain could be scaled in relation to
bandnoise levels.

To do this you would need to use a table with a few setting points across HF
and have gain or threshold interpolate between these points. This would
compensate AGC threshold or IF gain across the full range of the receiver in
relation to bandnoise levels.
(It would be nice if this were another industry-first from Elecraft :-)

BTW, an old trick I often used for receive-only is a rather small capacitor
in series with the RX antenna input, this gives a general decrease of gain
towards the lower bands, compensating the higher bandnoise levels.
