If you guys want to expend a lot of time and energy debating junk science hoax/scare myths you may as well focus on nonsense that's a threat to ham radio, namely the stupid bs about RF exposure limit
Graham, I have had pretty good luck with a Grundig Yachtboy YB400. I got mine on eBay for 50 dollars. It is a paperback book sized portable that uses six AA batteries. on 160 and the HF frequencies i

I think Dale's message was not the futility of mending one problem but the shear plethora of problems in a town or city. No one argues about the functioning of the process. The problem is that if you
There are a few variables you need to be aware of with reception of PTV RFI. It sounds different depending on whether or not you are listening with or without a BFO. It also depends on the passband o
All well and good working with ARRL and neighbors but hams need to grow spines and quit tucking their tails between their legs and capitulating to neighbors who due to irrational psychology, seem to
That's called municipal broadband and you are very fortunate to have it. Only a few communities have managed to set it up. Why? Because in many cases, the cost as a bond issue gets put on the ballot

That's a big clue which seems to have been ignored. If it _starts_ at 700 kc, then it probably isn't noise from an arc on a power line. Rob K5UJ _______________________________________________ RFI m
That's all true however those factors (antennas, feedline, matching networks etc.) don't provide a sharp cutoff high pass filter. If they were involved, he'd see a gradual attenuation in the vicinity

There are other perhaps better and cheaper ways depending on the application. I resort to ferrite only when all else fails. Audio and power line Isolation transformers and bypass caps are good. You
I am amazed that a ham can show up at a home with a loop antenna, etc. and the home owner will let him in to walk around. Around where I live, they'd call the cops. To me, showing up at a door with r

In the proceedings for AM Revitalization, the SBE has filed strong comments calling on FCC to get tough on RFI. SBE's focus was on medium wave frequencies, but deserves our attention and support sinc
