Jim and All,
Yes, it is good idea for me to track known leaking PLC signals. For now, I
am concerned about how strong my signals are in their lines. Unfortunately,
the fact that I am not causing interference is good enough for them... I
would like to measure how strong my signals are in their system in
comparison with their wanted PLC signals, and I believe that they will allow
me to set up a receiver and computer in their substation to measure these
things. I was the foreman of the maintenance electrical / instrumentation
staff and had done hands on maintenance of the SCADA / PLC system, and
because I am a licensed power systems electrician, they know I can work
around the substation safely. I feel good that I can convince them to let
me make measurements.
Believe me, Spectran and Argo will get a workout if they say yes as I
expect. It will likely happen next spring, after thaw and before the summer
load, when jeopardy to the Yukon isolated power grid will be the least.
When I am there I can track all of the PLC system frequencies that might
have changed since I retired and see how any outside signal compares with
the signals within their transmission lines. I strongly believe, and this
is supported by their senior PLC technician, that there will be no
interference at all. I hope we can prove it.
