I have really enjoyed the interchange going on. Great discussion. 

Just a little different thought flow................

I like experimenting with and building all the analog tube rigs, but with
the problems associated with heterodynes, and the advent of super stable
PLL oscillators, isn't there a possibility of applying direct conversion
here, regeneration even ? I know regens are usually poo-poo'd. I would
continue to focus on a very low noise highly tuned LC and tube frontend
for sensitivity and selectivity with a focus on high Q. Somewhat like a
tunable Q multiplier frontend ..... I guess that's basically what a regen
is in part. So what are the pitfalls of regeneration in addition to lack
of stability and how do you solve them ? Maybe, back off on the
regeneration and add the best solid state has to offer for the non signal
source osc, and finish out with tubes for the audio, ?
