Hi, let me try to clear a few things up being amatuer operator for a while.
I have worked 15 countries with only .100 watts of radiated power/////when
the band is open. So a TC with 500 or more watts if its only leaking a bit
of energy it surely is above .1 watts and radiating...and with todays
recievers of very high sensitivity very small radio signals can be heard for
thousands of miles. As someone already mentioned the low frequency and the
other uses at those frequencies should not be a big problem most of the
time. Being heard by a very sensitive reciever is NOT a good measure of
radiating signals. Sometimes interference can be reduced if the operating
frequency is moved up or down. I would be glad to try helping off list
