[Milsurplus] SCR-508 conversion info

[Jack Antonio]

HI all

We've all seen the ham radio magazine articles on how to convert various
pieces of gear to ham use, but I just came across a "professional"
conversion
article.

The NAB Engineering Handbook, circa 1960 or so, has a chapter devoted to
the conversion of the SCR-508 set to a one way remote pickup link for
broadcast
use. Actually a pretty minimal conversion, mainly involved in rewiring the
filaments
for 6 volt and using a PE-103 for a power supply.  Article suggests
repainting the
cabinets for a more pleasing appearance.

Article then goes on to say a BC-375 (or 191) can be used on a "talkback"
channel of 1606 kc (this was legal back in '60), after conversion to
crystal control.

Just thought someone would find this interesting.
