3D printed vacuum tube transmitter QRP CW QSO

Thanks for checking this out. Cw qso on a 3d printed tube transmitter.
I wanted to make something on the ender 3, and I´ve had this at the back of my head for quite some time. used the simplest transmitter design using tubes as I could think of. designed a baseplate, coil form and a compression trimmer capacitor for frequency setting.
Having a cw qso, as always with Finland, and also try out a very ancient form of AM modulation. Files are available at thingiverse, www.thingiverse.com/thing:489...

Very cool! Love seeing more makers join the hobbies of amateur radio and 3d printing

Looks so portable till you mention 300V plate voltage!! I love the combination of high tech additive manufacturing and nostalgic valve usage. Bit of happy chirp but 1 valve!!! You sir are a genius!!! Love it Could you suggest a valve QRP kit or is that unlikely to come by?

Hello. Will this transmitter work with unipotential cathode tubes (dual triodes with one large cathode spanning both portions, such as the 6Y7G)?
