Default "Cathode Ray's" Wireless World Articles?

How about gathering together all "Cathode Ray's" Wireless World Theory and Discussion Articles into one PDF like was done with L.L.J?

Does anybody know when he started writing them, and when his last one was?

I thought Cathode Ray was M G Scroggie?

It would be a good compilation, whoever he or she was!

I bought a book titled Second Thoughts On Radio Theory some years ago
by M.G Scroggie ( cathode Ray Of Wireless World ) in it's Title it was the
Third reprint in 1963.
A very interesting book. I am told there where later reprints.

World Radio History website has most Wireless World magazines available... a binary search should find the first and last ones fairly quickly.

He was born in 1901.

I think I've read an article by him from the 1920s, some sort of voltage multiplier IIRC.

So he goes back a loooooooooooong way.

Yup. 15th August 1923: a voltage raiser for a transmitter running off DC mains.

Indeed - and plenty of us cut our teeth on that classic borrowed from the public library!

I traced “Cathode Ray” first article in WW to April 1945, I have not traced his last. I have attached two pictures.

Interesting! A switched-capacitor step-up circuit - a technique still often used, especially at low-powers!

Except switching is carried out by MOSFETs in an IC, not by a motor driving a sectored disc across springy contacts...
