Hi!

I am doing a study into the early use of silicon diodes in radar and
communication equipment during the Second World War.

What I would be interested in is as follows:

-type numbers of the diodes
-name/type number of radar/communication equipment
-technical infor on those systems
-info on producers
-pictures of actual diodes, also "in" the circuits
-anecdotal stories about the actual use
-anything else!

As mentioned by another, Vol 15 and 16 of the Radlab series has a lot
of what you will be after. But also check out the Vol 17: "Components
handbook" that also has a fair amount on diodes.

Also, look at "A History of Engineering and Science in the Bell
System1925-1975" There are 6 volumes, ranging from 360 to about 1000
pages, and they all cover diodes to some extent.

The RSGB "Technical Topics" scrapbooks (there's now 4) compiled by
G3VA, Pat Hawker, also mentions WW2 equipments and components in many
places. He was initially a VI, then joined Special Comms and SOE
during the war.

I also had an interesting book by Philips back in the 60's on diodes,
long gone now tho!
