My radio shows about S4 noise on15m when the beam is oriented towards the nearest power pole. There is S3 noise on 10m and almost none on 20m and below. The noise is canceled completely with NB so I
What else is in that direction? One or more houses? A city? Any towers that hold antennas for 2-way or cell systems? Especially at higher frequencies like you're hearing, power doesn't travel very fa
Ignacy, I sent you a more detailed message direct. Have you got a VHF yagi you could more accurately pinpoint its direction? If so, does the VHF noise match the HF noise? Helps a lot if the noise goe
I want to "second" what Charles wrote! Always make sure the 'rabbit' you're after with VHF/UHF is the one bothering you on HF!! I have chased down 160m and 80m noise sources that were miles away and,
Jim, Reminds me of Gunsmoke. When tracking the bad guys, they look for clues to make sure its the right tracks :-). Chuck W4NBO I have chased down 160m and 80m noise sources that were miles away and,
This is critical! If you have a noise and 6 sources around you, you may hear only one of them. Some propagate down the lines for a long distance, while others are strong locally, but drop off rapidly

Don Have the IC-705 just as an RFI portable unitand has great Audio Scope and the ability to record audio file for analysis of the noise is a plus for locating RFI from BC, HF, VHF and UHF bands Wor
If you don't require "DC to Light" coverage with an SDR, even the USB dongles can offer you full coverage of any amateur band below 70-cm. Cost is quite minimal and HDSDR operates them and offers bot
