[Milsurplus] Foxhole Radio - conclusion

[Glen Zook]

The "blue blades" started to be painted in the 1950s time frame.  I remember the subject of "foxhole radios" being discussed in magazines like Popular Electronics in the late 1950s and early 1960s.  People were complaining that the "blue blades" then available would not work at all.  The reason noted was that the blades were then being painted instead of heat treated.  The suggestion of letting a "plain" blade rust was made to get a suitable detector.

Interesting.

When did they start painting them? I tried using one as a detector on the 1960's and had no luck. I went back to my 1N34 and 1N48's.
