I, for one, make mention when writing the power company on RFI
issues whether the source has a high likelihood of affecting Public
Service or aircraft communications and navigation frequencies,
including even MW/LW beacon frequencies in one notable case.
Perhaps in the future I should CC the ARRL and FCC in correspondence
with the power company? It would be good for incidence tracking
'stats' to know the number of interference cases that occur in any given
One such severe case of power line noise generation was adjacent to a
major north-south multi-lane highway (though not an "interstate") and
was quite pronounced in the VHF Hi-band spectrum, which is used by
Texas DPS (state highway patrol) digital P25 radio system.
The usual time for correction of power line noise is 3 to 4 weeks,
during which the 'noise' would have affected mobile radio comms in
the vicinity of that noise-making power pole for several blocks.

You guys that are more familiar with public service digital systems
(fire police EMS etc) than me maybe can enlighten me. Would these
sources of RFI that we track for our ham analog systems not interfere
with digital systems? But maybe go unnoticed since the users of the
digital may not even notice since the RFI just de-senses the digital
system to where the range is limited but what does go through is still
clear? And that limited range could affect vital communications?
That to me makes us tracking down interference immensely important does
it not? Its like we are doing a free public service. And the FCC should
back us up, if by just stern letters, for this reason if not for
ourselves (which they should).
Just a thought.
