[HBR] Hahnel Oscillator

[hbr@mailman.qth.net]

I had a request for the info on this oscillator -- a circuit which allows a 
very high multiple of a crystal frequency to be generated in a single 
tube.  (By locked oscillation -- not an overtone and not a frequency 
multiplier.)  Here's what I have -- don't go 'just for a peek' unless you 
have a fast connection, as these are large files.   Sharyn said that 
when she tried to reduce them, they became unreadable. 

These are from a U.S. Government publication 'Crystal Oscillators' so 
there are no copyright issues -- us taxpayers paid for it and we *own* 
the work.
