Radar days.

[alluvial]

Mostly because it wasn't used in Chain Home or Chain Home low, which were HF and VHF rather than centimetric.

Plus it was invented in 1940.

None of the kit shown seemed capable of producing the sort of power levels (300kW?) that were mentioned.

You need big valves (really big valves) for that power level.

And it cooks you if you're not careful with it.

One of my physics lecturers (I forget his name) used to tell us stories of working on the early radar stuff. Apparently on a cold morning, they'd go out and warm their hands in front of the things.
Hands looked a bit knarled but worked okay still.

Speaking of big valves, here's one from the Chain Home Low transmitter:

Not a specific mention of the Magnatron (except in the posts above), although it was alluded to.

Ah, good old end-fire arrays and their lobes.

I remember learning about radar at Willesdon Poly.

It's probably the University of Dollis Hill now.

And every time you heat sommat up in a popty-ping, thank Mr Randall & Mr Boot.

Oh, and Mr Colt.

FTFY!

I wonder how many appreciate modern day radio detection and ranging in phased arrays when mapping the surface of Mars and asteroids. Amazing topographical maps.

It's what we pay our taxes for, innit?

Mrs IJNTTI got nabbed there as well last year.

It's still a source of amazement to me seven years later that I never got done driving London-Swansea and back every week for nine months. It seems every bridge over the M4 in Wales is populated by a man in a camera van.

[I just need to test it]

Cockett Road in Swansea being the place where I got my first ever speeding ticket in 2011 after 30 driving years with nothing. 34 in a 30, Sun Morning, damn the Heddlu.....

I recorded it. Not sure if I'll get round to watching it as I think I can guess the ending: they did invent RADAR. Am I right?

Moderately interesting thing about Watson Watt on bbc2 this evening.

Taffy Bowen (born in Cockett, see, boyo) was in it.

Sort of drama-ed up the drama for suspense & I'm not convinced the implied timing of events was exactly accurate, but it filled an otherwise tedious hour & a half.

And I didn't fall asleep, which I usually do with Horizon these days.
