[GreenKeys] The BEST TU?

[Gerry Block]

So far, it sounds like they were all pretty good... everybody probably prefers 
the one they put the most sweat into.  I built a pretty decent TT/L2 from 
schematics given to me from Keith Petersen way back when.. of course I don't 
have it any more, but I remember it sure worked good.  I think I still have the 
schematics somewhere.  I'll bet the Frederick units were really good.  I was 
friends with Vic Poor's young protege whose name I don't remember but who was on 
the 80m autostart net and Frederick was busy doing a lot of work on this 
stuff... they licensed the DTC circuit from whoever it was that invented it..  
on the net some of us made crystal controlled receivers from prototype receiver 
boards given to us by Frederick that were of course drift free.  Lots of 
learning and lots of fun.

I've got a Dovetron here.  One day (when?)  I'll get it all fired up.  It looks 
like a very complicated but thought out design and I bet it works very well.

Gentlemen:

  I would like opinions on what was technically the BEST TU ever designed - and 
on what basis the opinion is given.  TT/L-2?  ST-6?  Frederick?  Dovetron?
