[Milsurplus] What is it?

[Barry Hauser]

Hi Dave:

That's a TBY receiver/transmitter.  The Navaho codetalker/windtalker radio. 
It's missing a few pieces and was subject to some mods -- like that octal 
plug in the front panel.  Inside view looks modded also, but I can't quite 
picture what's not right, other than those coils that look sort of tossed in 
there.  Not original equipment.

Here's a web page on it:

here's another:

another (in French)

Can't seem to find one offhand with an inside view.  There were two 
different antenna mounts -- one with that big bakelite thing and the other 
with the bracked and SO-239 style.  These I believe are 60-80 Mhz, 
regenerative.

The battery box plugged into the vibrator pack and the two plug into the 
bottom of the radio.  You might still see the connector on the bottom. 
 Also -- arbitrary tuning scales -- you'll see in the photos that there was 
a frequency meter style loose-leaf attached to the top.  Alongside was a 
small key -- removable.

There's a place in the lid for spare tubes - -some of which are acorns.
