There are a number of MW DXers who listen only for signals from outside the
Americas where channel spacing of 9 kHz is used. In that case, you can have
a 1 kw signal from New Zealand sandwiched somewhere between 2 nearby strong
50 kw US stations while using a long Beverage antenna.

I used to have such a setup - I was a mile from WSB 750 with 50 kw with a
1900' Beverage. I needed close to 100 dB of dynamic range if my meory is
correct.
