The Liechtenstein worked well until a German night fighter accidentally flew to an allied base. The RAF tested it and was able to develop chaff. The Liechtenstein was very susceptible to chaff, so the Germans worked on the microwave Berlin radar. The Neptun was a stopgap that worked decently through chaff, but was susceptible to primitive jammers, and could also be targeted by crude radar warning receivers. Indeed you have a very rare specimen. Definitely late 1944 (40th week is around September). I would so love to see the glow of your Neptun's CRT. It's possible that it could even be hooked up to a signal generator to show what the display would've looked like in combat.
As far as I know it displays a line with three bows in it, the central bulge is the highest one. If the nightfighter is aimed at a target the middle bulge peak lowers and the two outside bulge peaks will rise. When the target is in sights and you can hit it the line has three equal looking bulges in it (like the McDonalds sign but with a third curve)
The German night fighter that the British Captured with the First Liechtenstein that they got didn't accidently land at an RAF Base. Two of the crew defected bringing the third member as a prisoner at gun point. The British already knew enough about the system from its transmissions to be able to jam it with Window, but its capture allowed those countermeasures to be tested. The second one that landed in 1944 by accident exposed the SN2 radar which the British didn't know about.
Yes, it was quite common for German military tube hardware to use a minimum complement of tube types. In many receivers only one type of tube was used throughout, making it necessary to use more tubes than usual for one particular function.
I'm surprised it doesn't have swastikas stamped all onto that part label. I've seen lots of mechanical parts, pressure cylinders, stuff like that - which always have swastikas written or stamped onto them, the official mark of quality which meant they passed some official standards or official inspectors. War is hell, but the Germans were always extremely meticulous.
Seems a radar display unit rather than radar itself ...the connection at the back join the display to the radar output to the display and power supply ..
Hi - I think that what you got here is just the display unit - the signal generator and emitter/receiver where bulky stuff around 30- 50 kg ...it would be nice to find sombody knowledgeable about this old systems and maybe make a video presentation about this old systems...if you're right and this display unit belonged to the Neptune airborne radar system there must be some records about it in the British Archives ( maybe contact the RAF Museum in Hendon or IWM via e-mail ? ) because after the war the britts studied this systems extensively in order to comprehend the effectiveness of the german night fighter force....thanx.

This is the first time I seen a German radar scope, that's pretty cool to see.
I'm amazed about the general condition of the unit. Great video.
EIN = ON / AUS = OFF
Love the pull-out CRT, complete with handle!
the CRT is a LB 1 tube... I used to build several RTTY scopes with them in the 1960's... They had been available brand-new in box for US $ 1 each...
Amazing find - the radar scope certainly does seem designed for maintenance.
Roh 1, 2 and 3 are RV12P2000 Roh 4 LD2 and Roh 5 LG4 and the CRT LB8 according to the manual

That's going to be the most bad-ass CRT CLOCK ever!
Fancy meeting you here.
Thank you for sharing this video, really interesting , The electronic components are the same type used in equipment of 50s & 60s era .
Nice interesting video. On the crt the marking 40/44 means production in week 40 of 1944, week 44 of 1940 is improbable.

SG means Sichtgeraet which means "Display Unit"...
Высокое качество разработки и изготовления!

How hell didn't I find your channel before ?
Heyy msylvain!
Nice to see you around :)
Look forward to next vid.
The Germans are amazing !
Another Telefunken CRT: czcams.com/video/wNX4qLaTw4o/video.html
im jelly
it's wasted in your collection . have at least de decency to learn it ;)
Germans were amazing.
@uniservo >>> 👍👍
