Why DAX IQ stream during transmit (issue for CW skimmer)?

I am using SliceMaster and CW skimmer in the background while working some CW. It works great. I noticed however, that the SNR values CW skimmer reports are inflated. They are definitely larger than when I do not operate. That leads me to believe that the DAX IQ channel (which CW skimmer uses) is not disabled during transmit and it increases the SNR values CW skimmer reports. Is there some setting where I can disable this?  Its not a big deal, but the SNR values are not realistic (see for yourself, 60 dB from Europe to W7 is not possible: http://www.reversebeacon.net/dxsd1/dxsd1.php?f=0&t=de&c=ku7t).

Thanks

No, the IQ data is continuously streamed from the defined bandwidth of the panadapter it is sourced from.

Do you have FDX enabled?  If so, disable it.  That should help.

FDX is off. Using single panadapter and slice. What would IQ data be needed for during transmit?
