Hue - remember too  a nearby  lightning strike  would   take out a fixed 
detector...  it will also whack  the sensitive spot  on  a  manually 
adjustable detector... but there are always a  few  more spots  you can  find... so  
in a way... the   manual diddled one  has  the best chance of operating no 
matter  what....    Ed#

I have  not seen one of the 'emergency crystal receivers' among 3 
varieties, with a  fixed crystal. 
I think the early fixed crystals were somewhat fragile and  susceptible to 
moisture ingression?
But I don't have any evidence  marshalled. I'm just recalling some 
instructions that came with 
jim-crack  early toy crystal radio with fixed crystal.

or  were the later ones  replaced  with a simple   diode?
