What radars
Hi Guys,
Memories are slipping away and help is only needed because it's niggling me about radars at airfields late 60's early 70's. EGSS Plessey 430? (1972/1973) EGPF Marconi 264? (1967/1969). EGPH what was it in 1973/81, an ACR 1 or an AR 1. The annoying thing is I used them all and after 40 years my recall is dimming! All Zheimer has not here yet but after this post U may disagree!!
Thanks for any replies

PF Marconi S232?
PH ACR6?
I recall that airfield radars tended to be those, or variants thereof, in those days.....
I'm still using a 424, and no, that's not Alzheimer's.......

Not directly related to the OP but for those with an interest in such things, I've put the ACR 430 manual up here. It just amazes me how basic things were....and how much we could tweak the things ourselves!
Sorry - you've got to wait 60 secs before you can download the file.

Anyone got a magnetron or two lying around?
Edinburgh's first radar was an AR1, which became operational in 1970.
For reasons which were never totally clear, the Glasgow press published a photo of me doing Aerodrome Control to celebrate the fact!

Cardiff 1970s had a 424 and an AR1 (later some EN4000 series thingy)
Glasgow two 264's (as noted above)
Farnborough, AR1, 232 and CR62
Exeter had a 430, replaced by the first civil Watchman
Always thought Dunsfold had something after the 430, an AR15 perhaps (AR 1.5?)
Similar thought, who had the last wobbly line DF, as opposed to the later digital versions? (FERNAU?)

Cossor ACR6 at Bournemouth Airport, 1979, just before the aerial was removed to Stansted.
Marconi 264H, north side Heathrow, 1960s.
Plessey ACR430, Bournemouth, 1980s.

Whaddya mean "had..."?!

ooooooo! Digital DF!
I seem to recall if you press the "lamp test", bottom right, the lights all light up in sequence but end at a random bearing..... DF roulette anyone?

I seem to remember that Edinburghs' AR1 was in fact a EN4000 - AR1 aerial with Marconi guts. Why buy a complete system when you can bolt two bits together of two different systems? A least you know what you're going to get.....

Bedford Thurleigh late 1970s had a 232 and what I was told was the only 664 (a sort of derivative of the 264?). Needless to say they had a PAR of some description too, but being only a humble Cranfield Radar wallah, I wasn't allowed near that!
As has been said already, the blips on the 232 were enormous, so when you were about to run out of radar separation a quick flick of the switch to the 664 and hey presto! bags of separation again!
EMA started with a 424 but by sometime in the 1970s had an AR1. The 424 was upgraded with solid state guts and a Kelvin Hughes display, and remained in use for half-milers well into the 1980s. The guts were eventually sold to cambridge, while the head (minus 'twanged' rubber band) languished in the MT car park - the NOTAM still said it was simply ' u/s'....
Eventually it was formally withdrawn and now adorns the Aeropark.
The AR1 was replaced sometime around 1990 (can't recall exactly when) by a Marconi 511, initially with Cossor cursive displays and subsequently with the first CAA approved colour raster scan displays in the UK.
