crystal radio: the first real free energy device

TK:

Yes, your photo is exactly what mine appear to be.  Glass tube and all.  I may be mistaken on why I ordered them..about 6 years ago. I thought it was for the Bedini...but I might be wrong.  I will look at one under my microscope to see if there is any number on them...or...is there a color code for these like resistors?

I think I remember someone on a topic here saying that real germanium diodes were getting scarce and folks should get some before they are gone.  I bought about 50.  Did I send you some in that package?  I might have as they are in the same container as my 2N3055 transistors from my Bedini projects.  I might not have either...it is hard to say at my age...ha ha.

All I know is that I have missed 2 days of work here due to 12" of snow!!!  I do not get sick, vacation or any weather related days so...no pay.  I am going in the a.m. even if I have to walk the 6 miles to get there.  Oh, Thursday, they are calling for up (or down?) to -27 degrees with the wind chill, which is great as I work outside.

Here is as close a photo of my diode as I could get.....

Probably not real clear but...best I could do at the moment.

PS  I just checked one of my Bedini motors...I did use a 1N4007 on them.  I bought a handful of those at the same time.  Sorry for my confusion.

Yes, I think you maybe did send me a few of those. They look like 1n60 to me, which is a 100V germanium, similar to 1n34a but just a little higher voltage. Fine for crystal sets.

No, these won't have any numbers or color bands, just a black band or end for the Cathode. The one I've got with the color bands is the only one I've ever seen that looked like that. I don't remember where I got it, either.

Thanks.  So black is -, very good to know.  I will try building a simple set once we thaw out around here.  I just checked again, for Thurs. they are now calling for -28 with the wind chill.  Tomorrow is only -9 so, not as bad....ha ha.

TK, how far are you from the transmitter? 3V+ and a few mA is quite a huge signal.
I tested a few Ge transistors, using the base emitter as a diode and none give the same amplitude as a 1970s unbranded Ge signal diode.
