Since I have replaced my feed line with grounded coax I have noticed that
from 30 meters on up is almost completely free of noise.

I hope the desired signals are still there...Sometimes "no noise" is
not good.
However 120
through 41 meters is still pretty noisy.Could this be due to the impedance
mismatch?

No. If you had a really severe mismatch, you wouldn't hear as much
noise, as the whole noise/signal level would drop.
I am hoping this will be reconciled when I implement the matching
transformer between antenna and coax.

Shouldn't change much. It's normal for those bands to be noisy. I
would be much more worried if they weren't. MK
