Greetings to all from Slovenia!
One of my projects from 2007 Foxhol radio:

Hi Sabastian

Welcome to the Forum.

Nice job on the Fox Hole radio. I remember trying to make one of those many years ago but mine certainly did not look as good as yours. In fact, I don't think it worked either. Always thought that was a clever use for a "blue blade".

Yours shows great workmanshipand attention to detail. How does it work?

I always wondered just how many of those were built in the War.

Really a nice job and work of "art." Yes, I'm curious about how well it works also ?

My Foxhol work more poorly, receive only local station / 300kW / just a few kilometers away. At night there is nothing better.
To be honest, I did not do to listen, the more I wondered whether it works at all.

"We're doing radio" is the title of the 1929 book from which I made a replica of the detector, which works better. In the evening I hear two stations ........
Here are the pictures:



For the coil I used an old wire insulated with silk, wood is mahogany, my favorite material. I love working with wood and doing all the housing itself.











The detector is nothing special, but it is made exactly according to plan from the book.

Finally the stock diodes for Foxhol:

Gee, another great art work....outstanding. Yes, I like mahogany also. Haven't looked, but not sure the razor blades are plentiful here in the States....especially the Gillette Blue blades. You have a nice collection !!!

Sabastian:
That is the Mercedes Benz of foxhole radios! Beautiful. I build a crude version of the same radio many years ago (1962) which began my interest in the radio hobby. My coil was wrapped around a cardboard oatmeal cereal box tube. It worked well as I recall and I spent many late nights falling asleep wearing my earphones.

You have wonderful craftsmanship. Very nice looking units. I have very little personal knowladge of the internal workings of radios.
