Paul,
This is a cool article describing techniques that we still use. I was
especially amused by the shaking of the utility pole to confirm the noise and
the form factor of the ham shown in the photo. Some things never change! :-)
Thanks for sharing it!

Subject: [RFI] Tracking Electrical Interference in 1924
Using Brigg's description of the arcing street light location (i.e., 2nd pole
on School St. off Washington), the pole location and surrounding neighborhood
can be easily seen using Google street maps. In those old neighborhoods, it's
highly likely that even though the wood poles have been changed through the
years, the pole positions mostly remained the same.
Last year, I attended a funeral of a childhood friend in Dwight, IL. On that
visit, I searched for the home of G. Wiley Bergman, 9CA. Wiley was a prolific
spark operator in the early '20s. Bergman's station was described in a 1923
issue of QST. Taking that issue with me, I located the home and found the
antenna lead-in entry point, just as shown in the QST photos. The house looks
the same today as it did in 1923. QST photos also show placement of several
utility poles. I compared placement against the photos, and they're at the
same locations today.

Thank you for sharing this. Interesting how we can point to this as another
example of our “expertise” way back then !
