What do you mean by "splash"?

I have Beverage antennas of 450 and 700 feet, oriented toward my desired
targets *and* (unfortunately) a number of 50kw MW stations in the
Seattle/Tacoma area. I also have a 1 kw station 1.4 miles off the end of one
of the antennas. I have a number of S-9+65db stations on the dial, but my
R-75 and IC-756Pro handle them well. However, I'm not using the hi-Z input
but the 50-ohm unbalanced input via a Beverage matching transformer and
grounded, double-shielded coax.

Have you tried adding a transformer and the 50-ohm input?

I just wanted to share the results an antenna experiment I did tonight. In
the rain, no less.

The antenna was simple. 300 feet of solid core 20 gauge copper wire. I
ran it from the 500 ohm connector of my R-75, out of the shack and all the
way into the back yard. The yard extends about 200 feet, so I had to
double the wire back in the direction of the shack for 100 feet.

No mater what I tune the dial to, I'm getting splashed from the local 50
kilowatt am stations. The preselector doesn't clean it up either.

Every time I exceed 200 feet of wire, I have the same problem.

Weird...

Hiya, Guy.... That is exactly what I already have currently with one of my
roof antennas, the 200' "Frankenstein. That antenna is ideal !!!! A great
DX'ing antenna. Detailed info is on my web page. See the link in my
signature. I just decided to try the 300' wire with no additional dressings
like transformers or coax feeds. The end result... The local AM flame
throwers are strong enough to overload the front end even on an R-75.
