    So I dug this out of a barn, anybody here have any info on this. I'm clueless when it comes to cw and older gear. 20190609_101632.jpg

    I dont know anything about nothing, and nothing about spit, but that a cool looking thing, I assume is a 1 tube transmitter.

    It was Noah's maritime transmitter.

    Probably a single tube practice oscillator

    That's exactly what it is. Audio oscillator with key.

    Ditto, a morse code practice oscillator. The rheostat (thing with the knob) would have been a volume control.

    Are there any components on the underside ? Resistors, capacitors ?

    Would make a nice vintage restoration project.

    Just wires run on the underside, no resistors or capacitors.

    I think that belongs to Grampa Munster.

    You 'new hams' just don't know much about old transmitters. That's part of the keying circuit for when you use the high voltage of the final amplifier circuit in them old transmitters to do the keying. The thing there on the left isn't a transformer, it's a choke, and the socket is where you could change from keying upper side band and lower sideband, just change plugs to keep the wiring right. You had to be careful keying high voltage like that, it'd really gite you if you weren't careful. That variable resistor was to adjust the size of the spark when you hit the key. (Too big and it'd bite you at a distance.) You could tell when someone was using this thing, the tone changed... sort of a "peu" "peu" "peu" for 'S'. See what I mean?
