[Elecraft] K3, diversity and noise reduction

[Tony McRae]

I have been watching some youtube clips showing how by adjusting the phase and amplitude of two received signals on a diversity receiver local noise can be reduced by more than 20db.
This would be particularly useful to me as I have the dirtiest plasma TV on one side of me and a gaggle of cheap ADSL routers on the other. When pointed at them with my yagi the noise floor on 20-15m is over S7.

The equipment used in the clip was the ANAN 100D SDR.
Is anyone aware if this technique is possible using the K3 dual receivers?
I have not found any place in the manual where it is possible to alter the phase of the secondary or primary signals.

Thanks for reading this
