Hi Ken,
While there is no substitute for actually looking for RFI with antenna,
collecting data is always good...
See:
https://www.nk7z.net/sdr-rfi-survey-p1/
for how to set up and collect data over a long time period... Let it
run while you look around. Seeing patterns helps in location sometimes.
73, and thanks,

Does this happen 24/7 or only between dusk and dawn?

I normally have S5-S7 noise on 160m but recently I now have +20dB noise
that seems to cycle at approx 2.5 minute on/off cycles. I was not active on
160 in December but it wasn't there in Nov and I just noticed it in the
last week or so, so I really can't pin point when it started.
As an example, W1AW code practice at 1802.5 is typically 20 of S9 here.
When the noise comes on it wipes out W1AW.
Thoights?
