That's neat!

(It looks like the diode could be enhanced with an MK484 10-transistor AM radio IC. I discovered this component and just built the reference circuit with good results. I was reading about expanding the frequency response up to as high as 7 MHz.)

I still like the concept of a simple unpowered crystal set.

I've found that a genuine 1N34A diode seems to be the most sensitive, but the 1N270 is fairly close. I'm using 3 diodes in parallel.

Many thanks! Yes, the 1N270 is quite sensitive.
