Brian,

It is common During the DAY for all bands to be Noisier and
especially the lower frequency bands.


READ - Shortwave 101 "How To Listen to World Radio"
http://www.etoncorp.com/listeninggui...gGuide_new.pdf
{ TIPs on Listening to the Shortwave Bands }

Generally the Better Listening Times and Frequencies a

* Day Time above 13 MHz
= = = 31M, 25M, 22M, 19M, 16M, 13M, and 11M

* Night Time below 13 MHz
= = = 120M, 90M, 75M, 60M, 49M, 41M, and 31M


STOP - Before you 'add' a Matching Transformer to your Antenna
and Ground System.

FIRST - Get paper and pencil and record your current reception
for each of the bands.
(Note-Book and Pen - This is Now your "ANTENNAS" Journal-Ledger.)

NOTE: If your are "Organized" you will have a Separate Sheet
of Paper for Each Band. Each Sheet will be divided into two
Columns "Before" and "After".

WHAT TO DO: Select from three to five strong International
Broadcast Stations on Each Band: 120M, 90M, 75M, 60M, 49M,
41M, 31M, 25M, 22M, 19M, 16M, 13M, and 11M.

* Record your S-Meter readings for these Stations and Time of
Day/Night.

* De-Tune by 5-15 kHz to a 'dead-spot' on the band and also record
your Background Noise Level for the Band near each of these Stations.


SECOND - Now 'install' your Matching Transformer between your
Antenna Element and the Coax Cable Lead-in-Line and Ground everything
properly. THEN - 'Repeat' the "What To Do" Process again.


THIRD - Compare your Before and After performance and results
for the Matching Transformer.


TBL: Now You Know and have a Record of the Facts to refer to in
the future when problems occur or when your want to make more
changes for 'improved' Antenna Performance and 'better' Reception.

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. However 120 through 41 meters is still pretty noisy.

Could this be due to the impedance mismatch?

I am hoping this will be reconciled when I implement the matching
transformer between antenna and coax.

I'm not sure if I used that in the correct context but I guess
you get my meaning.
