It's probably redundant but I'm obviously "in", Les.   In fact I've been 
experimenting with homebrew DSB on my own, and there's an active 
discussion right now on the Glowbugs list regarding the "Islander" which 
is a homebrew DSB transceiver from Cuba that has been promoted over the 
years by Arnie CO2KK as a means of getting new hams on the air cheaply 
and easily (if I may borrow that phrase).   So I agree that would 
probably be the better forum, especially since I've already got the 
green-light from the membership there.   If traffic gets so heavy that 
people complain, we can always splinter off a new group but I hate to 
see balkanization unless it's really necessary since developing an 
understanding of each building-block of circuitry is of value to many 
who may have parallel interests.

For example, the double-tuned RF input stage just described was noted as 
a good way to add selectivity and passive gain to low-cost shortwave 
receivers.   And while I'm personally more interested in simple one-band 
DSB right now, virtually everything is transferable to a filter-type SSB 
rig, and more complex conversion schemes to cover multiple bands with 
more features.   As I've stated on Glowbugs, I think  DSB, especially 
using tubes, was leapfrogged by newer and better approaches back in the 
day, but still offers a lot of bang for the buck for experimenters today.
