[Elecraft] [K3] K3, SDR-IQ and CW Skimmer

Hello all,

I have searched through nabble and found some similar posts but no 
definitive answer as to whether my current goal is possible:

K3 using SDR-IQ in IF mode with CW Skimmer

The above scenario functions but the CW Skimmer spots have a display 
frequency of the IF and not the K3's actual frequency.

I have configured Skimmer's Omni-Rig for the K3. When I start up Skimmer 
I can see that Skimmer opens up the CAT port but the frequencies 
displayed in Skimmer are either relative (+/- 20 kHz) or if I enter 
8.215 MHz as the Skimmer frequencies then the spots have an "absolute" 
frequency +/- 20 kHz of the IF. I really want to see the frequency of 
the actual spot!

I am using CW Skimmer in SDR-IQ mode.

I have LP-PAN working with Skimmer in Softrock-IF mode but the 24 kHz 
bandwidth limitation is frustrating.

Has anyone got the SDR-IQ to work in IF mode with the K3 and CW Skimmer? 
Alternatively any other way to achieve what I am after - K3-IF mode 
skimming with a bandwidth of 96 kHz or higher?

Thank you for any assistance with my goal.

73 de Rich, G4ZFE
