Thanks for the reply starman. If you don't mind my asking, what are you
using for an antenna and what is your qth? I'll post my results after adding
the transformer.

from 30 meters on up is almost completely free of noise. However 120

mismatch? I am hoping this will be reconciled when I implement the

transformer between antenna and coax. I'm not sure if I used that in the
correct context but I guess you get my meaning.


The transformer (unun) should help to smooth out the peaks in the
antenna system making it more broadband but it's also likely the noise
levels in your area are higher for the low end of the HF spectrum. This
is typically the case for many listening environments.
