All I can tell you is what the manufacturer says, and they call the
two settings on my RADAR "Transmit blanking on" and "Transmit blanking
off"

It has always been my understanding (perhaps incorrectly) that
transmit blanking was offered as a safety feature where the scanner
was located too close to the helm position. If so, that would surely
indicate that the transmitter was being turned off, not the receiver.


While Bruce sure sounds like he knows what he's talking about with some
modern units I remember from school it being transmit off during
blanking, but I learned on really old stuff and my memory of it is just
too rusty to trust. I will have to look for my books on it and get back
to you on this - may take a few weeks to find 'em though...
Wish I still knew the radar tech on the ship I worked on in Africa
(circa 1974), now *that* was a radar! It was one of the big weather
radars with an enormous antenna in a huge *golf ball* radome, an a
pretty large room full of transmitter.
