By the sound of it, Lenny, your R8 is fine, but your noise producer took
a holiday briefly to allow MW signals to show through.

You might want to see if you can find what is producing the noise by
checking the examples  at  *The RF Noise Identification Website*
at:

(this recently posted here by Curt Deegan; thanks!), and see whether the noise producer can be switched off while you're DXing, replaced with something less noisy etc.

Finally, given that the noise is not bad out in your yard, and that is where your antenna is located, can you re-configure your antenna so that it, and its end point is as far away from the house as possible, then use a separate ground rod out there, and an isolation/matching transformer to drive coax back to your radio?  Ground isolation does wonders with local noise.  I can give you more details if you don't already have them.  (Maybe Lynn could post the relevant pages from a DXer's Technical Guide as a public service, as well as advertising the book??)  There's also details on the dxing.info website articles.

As has already been mentioned, if your house is electrically noisy, using an indoor loop antenna like the Kiwa, will not be advantageous.

It would be nice to get the R8 performing to its capabilities.  Good luck.

best wishes,

Nick
