Topband: Poor 160m DX Propagation

[Roger Kennedy]

I get why many of you in North America may not be active at the moment, if
there's now a lot of QRN (let alone risk of lightning strikes) . . . 

But are the poor RBN reports lately due to high QRN over there, rather than
poor Propagation, do you think?  (given that RBN shows signal strength above
the Noise, rather than absolute signal strength)
