At the museum here we have Gernsback's ( yes the same Hugo G. the Hugo sf
award is named after)radio and television news, prior to that it was
separate issues called 'radio news' and 'television news'. The dedicated
'television news' issues had the most wonderful covers.
Early Radio and Television history is interesting to study!

Unfortunately, my oldest 'Practical Television' magaizes are from 1952, I
think. I have about 3 years worth from then, then a large gap, another 3

stopped wasting money on it...)

Presumably your radar CRT is electrostatically defiected, which makes
varying the scan rate a lot easier than if you were using
electromagnetic
deflection. I found
'Newnes Televsion Handbook' in a second-hand bookshop a few
years
back. I don't think they realised what it was, the price was pretty
low.
It covers _only_ mechanically-scanend stuff....
A very lucky find! I recently got hold of some "television and
shortwave"
magazines from 1935 to 1939, which cover the late mechanical and early electronic systems (the Baird 240 / EMI 405
competition and such like.
There
is also a lot of information on the development of the Scophony

scanned 405 line receiver (I have one of the few remaining parts of a
Scophony set, http://www.g1jbg.co.uk/tv1.htm)
Ooooh... A very nice find there...
