[Milsurplus] FT-241 LF Crystals as a Long - Term Investment Instrument

[Hubert Miller]

I had this bag of those WW2 FT-241 LF crystals, which were used in the WW2 era FM  and ship radios.
I realized I needed to finally make an executive decision on it, so I tested them all. I used the little Chinese
crystal tester I bought off Ebay for $12 or $18. I connected a couple alligator leads to the LF crystal connection
points on the tester.
Result: 74 defective, 13 working = 85% fail rate.
I did find one possibly good frequency, 457 kHz, but - for how much longer ?
Well, this kind of ends any fascination with possible uses of the LF FT-241s for me.
