[Milsurplus] Alternate source of Sandretto book

[Mike Hanz]

Thanks, George - good info.  Eddy's book is good, and if you go further 
back in time you will see that his first edition is actually in 1931!  
Even the frontispiece of that early tome reports him as Lieutenant, USN, 
Retired, so he was an old timer by 1939!  Another good reference is H. 
K. Morgan's book on the subject -

Eddy (1939) has some stuff which Sandretto missed, such as the pre-war HF frequency assignments of the commercial airlines, several schematics of WE and RCA stuff (AVR-8 Airborne DF, anyone?), and discussion of the why and wherefore of *some* of the frequency selections and so forth.  And, some information on the 75 MHz marker beacons (UHF, they call it) which I previously thought were a few years later than 1939.
