I'll bet that rivals the purity of some Gates BC-1G transmitters up-banded to 75 Meters ... not entirely kidding either! For instance, see watch?v=bEGLazX68-A as an example ...
BTW, thanks for the video!

And one reason it was oputlawed was that it would splash its signal over a wide swath of the spectrum. By 1923, when the broadcast band extended close to 1400 kHz already (to expand to 1500 by 1925), this thing wouold have wiped ouot the top five or six channels on the AM band with splatter every time it fired up.

k FUNNY VIDEO! The cat Tim a.k.a. Red steals the radio components from the home lab. Of course, for the own secret project...
Кот Тим ака Рыжий из Киева регулярно тайно крадёт радиодетали из домашней лаборатории своих хозяев. Естественно - для его собственного секретного проекта! В этот раз его застукали...

What is the maximum range of radio transmission? How far can the signal go?
-
very cool
-
mechanical oscilator ?!? Operating at what freq? (or should i say... BAND since i bet it takes a whole band through missing filters i guess.

Something to behold in-person if possible. Hope to get the chance someday. 73

I'm guessing that's not hooked up to an antenna :D. Need to see one really run, though.

In the days when such transmitters were used, a set like that one, connected to a good antenna, had a reliable range of 1000 to 1500 miles on 200 meters.
Spark was outlawed decades ago; the transmitters in the museum feed dummy loads.
