I have an RFI source in my neighborhood that I'd like to track down,
but could use some advice.
The noise source sounds like a "click" or small burst of energy at
approximately 1Hz. In other words, I hear a burst of RFI a little
faster than once per second. It seems to be relatively narrow band.
I don't hear it below 17 meters. It is strongest on 17 meters, but I
can sometimes hear it on 15 meters and maybe even 10. I've never
heard it above that. I have DF'd the general direction using my tower
mounted HF yagi and the RFI peaks at about S7 or S8 on 17 meters which
is fairly strong, however I can't hear it when I walk the neighborhood
in that direction with my FT-817 and a whip. I obviously can't carry
a 17 meter yagi around the neighborhood. What other decent antenna
can I use to DF something doesn't appear to be broadband enough reach
into the VHF region?
FYI - The strength of this noise source varies from day-to-day and
some days I don't hear it at all, but it's there most of the time.
