Author Topic: Broad noise on 80 and somewhat on 40.  (Read 647 times)

Ok, I have a Kenwood TS450S and a 40 meter dipole.  I get "natural" QRM on 80 meters, at a consistent S9.  By natural, I mean I do not hear any 60Hz AC or other noise that sounds man-made.  Listening on CW, most if not all CW stations are right at the noise floor which means I don't make many contacts on 80 meters.

On 40 meters, I would say the QRN is not as bad but it is consistently S5 and can go up to S9 on occasion.  CW stations do much better for me on 40 and it probably shows because I have made most of my contacts on this band.

BTW, on 20 meters, there is practically no noise using the same antenna and if the band is open, I can work other stations.

Any ideas on how to reduce this QRN?

Thanks!  Joe N0NS

Did you check it on "am" on the bands mentioned?  If you hear a raspy buzzing noise on "am" it could be powerline noise.  Hope this helps.

What's your antenna?  Where do you live, rural or urban, etc?
