Yes, one of the most probable problems. I've read the story about the
GPS outage in that harbour, as I remember it was caused by a failure in
one TV antenna amplifier on a boat - but I don't remember if it was an
isolated case due to a failure (or to a bad repair replacing the part
with a similar one), or was a more 'endemic' problem :)
