[Milsurplus] fact checking props on Mysteries at the Museum! Why Linki using a HP 200a or b?

[Gene Smar]

This month's QST has a construction article on a modern version of the HP
audio oscillator.  Apparently the key to its stability is an incandescent
bulb in the feedback loop.

I love this  Mysteries at the Museum show but  sometimes  some of the pros
they use are a bit off!

 

FACT checking props on Mysteries at the Museum! Why is link using a 200 A or
B HP audio Oscillator!  there he is at a work bench with this HP thing  and
a set of bellows  allegedly 1929  era.

 

opps~~~

 

from history...

The Origin of the Link Trainer. Today in aviation history, on April 14,
1929, Edwin A. Linkfiled his patent application for his first Link Trainer, 

 

and  what of HP first product? the  200a and  the special one  for Disney?

 


1938


*         Work begins 

*         HP invents first product 

*         Oscillators for Walt Disney

======================================================

ok....  there we  go! just can't be near 1929.. now  I am sure  some time
Link   Had or his people used  early HP stuff...

but not  in the  time  frame as presented in 29 or  neat  29.
