[Milsurplus] LF & HF Crystal Tester prelim comments

[Hubert Miller]

I don't know this for a fact, but sandstate dipmeters might not have the umpfh to tickle some LF crystals. TBD.

>I have may home brew and purchased crystal testers. But my got in the tube one using a 6AH6. It has a 1ma meter to monitor activity of the crystal and a pick off to run to a counter. I can check crystals from 85KHz to 40 MHz with out any problems. I have used GDO's in the past and they do give you a reading. But what frequency your on is a S.W.A.G.
