During 6 years of apartment living, I experienced such high noise levels that HF and VHF-Lo monitoring were effectively impossible.
Now that I'm back to owning a house, I thought that I could finally get back to listening < 50 MHz. Wrong!
I find that I am still experiencing S9+ of noise on my AR5000, which tapers off above 60 MHz and is gone by 88 MHz. The antenna I am using is a longwire, no balun, fed by RG8X, with a ground at the point where the coax exits the house. I have, of course, tried turning off all the computers in the house. No improvment.
Relocating the receiver and feedline to the detached garage helps, but I still see a lot more noise than I think I should.
I have been a Comcast subscriber this whole time, and I now suspect that the interference is most likely comming in through the cable.
Can anyone confirm that Comcast causes problems like this, or offer a better explanation?
