I've got a strong 6M noise source from a solar system at the edge of my
property, about 400 ft from my 6M antenna. I want to put a 3-el Yagi at
it and use it to cancel that noise. Ham noise cancelling hardware that I
know of is all geared to HF.
Over the years, I've heard of CATV operators using this technique to
kill on-channel QRM from distant stations, so I'm thinking there must be
hardware to facilitate that. Anyone know anything about this? Any other
ideas?
Ultimately, what you need is something with variable phase and amplitude
and a DPDT switch. it doesn't have to be particularly linearly adjustable..
Something like a pot and a variable capacitor might work for the
amplitude adjustment and phase feeding into a power divider of sorts
(cable TV splitter?).
