And as you say, a salute to the remarkable achievement of the guys (I 
assume they were all guys back then) who kept them on the air with 
nothing but chewing gum and a slide whistle -- and the designers who 
made that possible.

With respect to military radio techs, I'm reminded of the Technician's Prayer:

I, the willing,
Led by the unknowing,
Am doing the impossible for the ungrateful.
I have done so much,
For so long,
With so little,
I am now qualified to do anything with nothing.


Best regards,

Don
