[aprssig] Radio Pirates

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.
