True enough. Most of the technical stuff involved in maintaince of
modern Maritime Radars would be in the OEM's Operations and Maintainance
Manuals and 99% of the Qualified Tech's in the field gained their current
knowledge via OJT, and not from books that would be obsolete before they
gained an circulation. The basics of Radar Technology was worked out at
MIT in the late 30's after trading the British Magnitron Prototype
for all those Lend - Lease Destroyers.

That triggered a nostalgic moment Bruce, I recall reading the entire series
of the MIT Radiation Lab textbooks published at the end of WWII. The books
had quite a bit of dust on them in my college library when I found them in
the early 60s. It turned out one of my school's physics professors (actually
vice president of the college by then) had written one of them. I think we
more that got our money's worth in the lend-lease trade for the technology
transfer/catalyst from the UK.

Huh?? The first radars were on VHF! They operated on common vacuum tubes,
not microwave magnetrons. http://www.bbc.co.uk/dna/ww2/A591545

Larry,
Did you read the info on the link? The first radar system was the
British Chain Home (CH) that operated on 20 Mhz. My frequency chart
lists that as HF.

Does anyone no any good books on marine radar repair?

I guess not.
