Mike, you have probably hit the nail squarely. I can tell you from my
experience
that dxing weak sigs in a big "noisy" city is a hopeless endeavor. After
moving to
a semi-rural area the difference was enormous. I finally learned to
understand
what a receiver's noise floor limitation meant.

Take your R75 to a quite country location as far out as you can for a
weekend
and you to will be surprised of even the most modest receiver capability.
Of
course you can spend more bucks on a Welbrook loop, etc...


Yes, very good point. In a quiet, rural location, sometimes you can outdo a
great desktop receiver in the city, with a humble portable.
