My new headphones
 
Got this radio earlier this day.
Now I just have to see if it's fully functional, hopefully I don't have to do anything except installing the crystals and then this little beauty should be up and running. Don't know how old she is. Found her in a box, wrapped up in newspapers from 1942 so around there I presume. By the way, any other operators on this forum?

Impressive :)

Nice resistor in the last picture :P

Never done it myself but I understand the principle and the systems to a degree (although I will admit I don't know all the different letters in morse code :P )

Um, yea... I guess you could call them that. The higher impedance the better conversion to sound waves.

You don't need to know morse to get a license in most country's. Telegraphy usually have it's own license. I don't know it myself, PSK31 is my main media :3

Steampunk headphones. :awesome:

That's pretty cool, I'm guessing you're just missing some germanium diodes, yes? Idk much about this, but I remember listening to AM radio with a long wire, a diode, and some cheap phones from the dollar store.
