I have been wondering about this for a while. AC line filters for HF
are everywhere. Most are characterized up to 30 MHz. Are there some
that work well at 147 MHz? I got tired of digging through data
sheets as they all seemed to be for HF.
At the moment I'm trying to stop RFI from a computer. When "sniffed"
with a detector the case seems quiet but the AC power cord certainly
is not. The first three Fair-Rite 0443164251 snap on cores helped
but adding more after that didn't. The line cord and associated
wiring in the building is still radiating noise.
Thanks,
