Successful TPU-ECD replication !

[WaveWatcher]

Don't give up folks! I've been watching your progress in AWE. Just recently I've had a chance to read the docs and the threads. Remember, SM was a tech of the first order. That is, his experiences are different than yours. i.e. vacuum tubes, the first usable solid state devices, reciever types that are no-longer used etc.

I too come from that time and maybe a little earlier.

GE abandoned a single gun CRT using toroidal deflection coils that were basically three coils in open air. Only the first was fed three frequencies. The second and third had only inductive coupling to the previous coil. Each succesive coil would have resonated to the next frequency and always seemed to have more turns than the previous coil. I do remember the second and third coils seemed to have no end point. I was populating my junk box and needed the wire.

I remember the stories about these things blowing up. It makes me wonder if they accidentally created some self-regeneration. I know they played havoc with other radio receivers.
You may wish to lookup the operation of a 'regenerative' and 'Super-Regenerative' receiver. This is old stuff but they had very interesting properties.

I will be building one of these soon. I'll let you all know what I find.

very intresting, Wave Watcher.
Thank you

bingo!

another one is the lemw transmission line

Sorry! My mind is showing my age.

It was one frequency (around 18kHz- horizontal sweep), three signals, 2 was 120 degrees lagging the first and 3 120 degrees lagging the second. If memory serves there would have been nine coils wired in groups of three coils per circuit. I don't remeber if the individual circuits were flipped between coils. i.e. like a Mobius.

well if there is anything which comes to your mind, please just post it.
i found the television story quite amazing.

Thank you.
