We have a customer who contacted us regarding "RFI" at his home station.
We were able to trace a single source to an underground water pump
operated by Metro Water. (What a weird noise that was.) Even though
that noise is clear, he is still complaining about what he believes to
be RFI on 75m with his SteppIR vertical . Using our Radar Engineers
MODEL 240-A, we are able to see an elevated noise floor, but there are
absolutely no distinguishable power line signals. The "noise" is also
audible/visible when mobile in his neighborhood. Other than the usual
isolation techniques inside the home, how can we help him determine the
source of a signal that has no noticeable characteristics, other than an
elevated noise floor? Realizing that this is no longer the power
company's responsibility, what recommendation would you offer him?
