In the mid 1970s we started receiving interference on a 164.10/146.70
MHz amateur repeater.
This occurred about daybreak and the voices had a British accent.
This occurred a few times a week.
After listening for a while it was determined that these were ship
board radios used for line handling while maneuvering a ship, with
tugs, in the port.
A call to port operations got an identity of the ships moving at that time.
There was one common owner.
All for their ship were registered in Great Britain.
A call to the FCC yielded the answer that this way a ham frequency, I
was a ham, the ship was an intruder, to contact the ship master on my
amateur frequency and inform them that this was an amateur radio
frequency in this country.
The FCC stated that they would have to get the State Department
involved for legal action if needed.
It turns out that the radios in use were licensed for ITU Region 1,
not Region 2.
It was not long after this that I received a somewhat threatening
call from the US representative for the ship line that I had cost
them a substantial amount of money with my complaint.
They had to change the radios and get new licenses.
I told them that it was not my problem that they were not in
compliance with international treaty.
That was the last that I heard of them or the interference.
I guess that wrong frequency operation can happen to even the big boys.
