It should be said, in 1929, they wouldn't have powered down to move the loading coils into place, they would have just done it.... probably with one hand on the key even.
Actually this transmitter runs FM all by itself if I'm not careful. Notice I don't have it on my operating table. Normal shaking of the table during transmming can cause the large copper coil to vibrate. Any vibration turns into frequency shift that sounds sort of like a bell ringing...not a good CW signal.
I'm running my TNT transmitter at only 315 volts on the plate....relatively low but that is kinder to the tubes. Typical plate voltage was in the 500 volt range. 315 or 500, both are lethal so I'm careful around it.
Thank you for posting this! Same with your website too. There aren't enough hams posting the really old equipment like you have. In a small way, this motivates me to study for the ham license exam so I can one day make use of some of this historic equipment as well. -- Chris
Amazing what they had to do to operate back then. Very educational, thanks for this great series of videos. 73, Tom N2BEW

That is too cool! Thanks from a relatively new HAM.

can you operate this rig in FM?

What is the plate voltage of this transmitter?
