I don't want any extra knobs to turn that's for sure. One post talked about
propagation noise over receiver noise or other noises. now we're reaching
the limits of my knowledge. I don't know what propagation noise sounds like!
So that in itself is a problem. I use an old R8 and it doesn't overload I
know what that sounds like. I was just hoping that on occasions that I could
possibly eliminate cross talk on frequecies that I cannot tune out thru the
passband. It is the same type of problems that everyone has who loves to
listen to the radio and DX. I just thought that the Preselector might be a
tool that might be used to reduce a little noise, intermod and other types
of interference. Sorry folks I don't know all the terminology I just like to
listen and tinker a little.

If anyone else has something to share on this subject I am interested to
here what they have to say.

If you set it for "unity (zero) gain", what you have is an additional
tuned RF stage that gives extra RF selectivity, and it can be a
blessing on a weak station. However, most people try to use a
preselector as an RF amplifier and cause more problems with intermod
and cross-talk than they already had.

They can be a useful tool, but they are not a cure-all.
