What does high noise floor 80m and 40m mean?
Discussion in ‘ Antennas, Feedlines, Towers & Rotors ‘ started by W8MCC, Mar 17, 2018 . Hello everyone, I need advice for solving a high noise floor > than S9 on 80 and 40 meters. Description of noise: White Static; no hum, no tone, no discernible pattern.
What can I do about s9 noise in my house?
Radials are necessary, of course. It’s beginning to sound like that ground-mounted transformer is causing your S9 noise issue. Try using a portable radio tuned to the AM BCB and see if the noise jumps up the closer you get to it. If not, it could still be another transformer in your area.
What should background noise be when 20m is dead?
Resolution (ish) – Confirmed with a local ham that when 20m is dead, he reads background noise less than S1.5 at the most with his setup. – Powering down the entire house (all breakers off) and running the radio off the car brought noise down to S3 or so.
Is there QRN in the 20 meter band?
I’ve noticed that the 20 Meterm band seems to have lots of background noise (QRN) everywhere in the band. The S-meter is sitting at 7 constantly. By comparison, 30m is at 5, 40m is 1, and 10m is at 1. Of course, this is connected to the same 20M antenna.
What kind of noise is at 80 meters?
Hello everyone, I need advice for solving a high noise floor > than S9 on 80 and 40 meters. Description of noise: White Static; no hum, no tone, no discernible pattern.
How tall should dipole be for high noise floor?
Dipole lengths terminate around 5 to 6 feet above ground with insulators and 10′ of nylon tow strap to keep them tight to earth anchors. Does anyone know what I can do to eliminate or drastically improve my noise floor?
What does it mean when noise peaks on a band?
When noise “peaks” on a band or two and is better on other bands, that can be an indication that “something” generating or receiving the noise is resonant where the noise peaks. That could be house wiring.
