Not tried one myself, here's a companion transmitter maybe....There is a version of the transmitter on the web that doesn't use an xtal, just a series tuned LC circuit. Link below:

The negative resistance oscillator using zinc was generally attributed to Losev....The Crystodyne.

I remember a story of the foxhole radio some years ago but have forgotten where I read it. It referenced the QST article and Jack Gould's book (which incidentally was my first radio book and is probably around here somewhere. The only other plans I had were in the Cub Scout handbooks and were essentially useless for lack of critical details. I could never get a crystal set to work despite living near some large broadcast stations, and no one in my family knew anything about radio).

If anyone cares, I found the definitive reference to foxhole radios: "Radio-Craft" for September 1944, p.730. That lists all the references in contemporary newspapers and magazines, starting with the "Field Artillery Journal."
