Hi,
I just found a 1000c/s (yes 1kHz) quartz crystal at a local radio car boot sale. It's a NOS GEC "Quartz Crystal Unit" type DJC/669. It's in an overlength minature valve (tube) glass envelope. The crystal is a long slab with 3 connections. The 3rd connection seems to be a small (feedback?) electrode. What's the lowest frequency crystal made? Anyone have any suggestions for an oscillator circuit? Robert G8RPI. __________________________________________________________________ Sent from [1]Yahoo! Mail. A Smarter Email.
