[1000mp] Important question

[Jeff Maass]

Noel:

At the Signal Point station (PJ2T), we have good bandpass
filters (W3NQN) on all stations, lowpass filters (Bencher)
at the output of each amp, and coaxial stubs in place. 
All equipment is properly grounded. 

We still have signals, albeit much reduced, on harmonic
frequencies on other radios in the station. I don't
think it's possible to get rid of all vestiges of them
on our little half-acre antenna farm: we just manage our
frequency choices to minimize interference problems from
them.

Move *off* of the harmonic frequency, and there is no
sign of interstation interference between any two bands
with properly applied technology. That's the real goal.

Someone else mentioned the book "Managing Interstation
Interference" by George Cutsogeorge, W2VJN. It will answer
all your questions, and help you think of more!
