[Milsurplus] 1905 Aircraft Radio

[D C *Mac* Macdonald]

I'll bet that that there are THOUSANDS of radios

on that list that are still in operation in aircraft!!

 

I know from experience that at least some of them

are fully capable of the 25 kHz chanellization that

is most common today.

 

It's an interesting list, though.  I have worked on more

than just a couple of the radios on the list!
