Yes, this is my impression as well.  I am mainly interested in looking at the 
multiplexing circuitry, as I am working on a poly design with many vcos, and 
I have been given what I think is some very good advice about using linear 
vcos and a multiplexed expo conv  (al a Trident & Polysix).  Unfortunately, I 
don't know much about how to multiplex and be able to tune and lin FM each 
vco separately.  My experience ends at building single expo vcos.  I haven't 
seen much on this sort of thing on the diy gurus' web pages.
Any advice from anyone would be greatly appreciated.
Thanks,
Kevin
