This group is devoted to Navajo Code Talkers, windtalkers and the USMC/Navy TBY series transmitter and receiver. They were a low tech version of the Enigma crypto machine. Heros during WWII, they did not even have the right to vote when they returned home.

The TBY series designed by Westinghouse in 1938 covers 28 to 80 MCs in four bands, with about 1/2 Watt output power for both AM and MCW. The TX is a modulated oscillator which will FM about as much as it will AM - works fine with the regenerative receiver which is quite wide. The calibration book is located on the top cover of the radio, as is the telegraph key and transmit switch. The meter measures TX RF oscillator plate current, or can be switched to measure RF section and AF section filament voltages - originally intended for use with a dry battery, the TBY has provisions to adjust RF and AF filament voltages as the battery discharged. The TBY uses 1.5VDC, 3VDC, -7.5VDC, & 150VDC, and could be powered with either a dry battery, a combination of a 4V lead-acid battery & vibrator pack, or a 110 Volt AC/DC power supply. The TBY and TBY-1 were Westinghouse made, the TBY-2, TBY-4, TBY-6, TBY-7 and TBY-8 were made by Colonial Radio.

Who are the Code Talkers?
The Navajo Code Talkers, whose ranks exceed 400 during the course of World War II in the Pacific Theater. Have been credited with saving countless lives and hastening the end of the war. The Code Talkers served in all six Marine divisions from 1942 to 1945.

The Code Talkers primary job was to talk and transmit information on tactics, troop movements, orders and other vital battlefield information via telegraphs and radios in their native dialect. A major advantage of the code talker system was its speed. The method of using the M-209 cipher machine often took hours, the Navajos handled a message in minutes. It has been said that if was not for the Navajo Code Talkers, the Marines would have never taken Iwo Jima.
