[Elecraft] K3 needs survey -- firmware and application software

[Wes Stewart]

If I use my XG2 as a source into the K3 and set the SSB BW to the default settings for my 2.8KHz 8-pole filter (100Hz to 2.9KHz) the signal which is S9 at its peak is still S7 at zero beat.  A 100 Hz beat note on the wrong sideband is still S3 and a 200 Hz beat is >S1.

The equalizer has no effect of the s-meter.  

If I run this same test on my TS-870, even with the lower pass band set to zero, there is no opposite sideband, nada, zip.  That's because the '870 uses the phasing method of detection in addition to crystal and DSP filtering.

I am no DSP expert but I have been told that this would be pretty easy implement in DSP.  So why not do it?
