[R-390] SSB Product Detector

[Stan Gammons]

Hi All,

I've been away from the list for quite awhile. But some time ago someone 
sent me the schematics of a SSB product detector they made. I forget who 
sent me that. It used a MC1496 and 456.3 Khz and 453.6 Khz crystals. 
Since we lost ICM, there isn't very many options for crystals anymore. 
Bomar has a minimum of 10 pieces and QuartSLab wants big $ for low 
frequency crystals. Anyone know of another source for crystals?

Thanks
