Jeff, great memory, found a post dated 11/29/1999 from G3RWL (with the 
descriptive subject "Re: Inquiry"). It refers to the G3RUH auto-tune 
circuit that utilizes the mike click methods.


Alan, perhaps I can tap the VFO selector and switch back and forth 
between mike clicks? It's no CAT interface, but maybe it'll do.

By the way I noticed the archives only go back to 2/98. Is there another 
archive that goes back further, or is that the whole -bb?
