The Talkie Tooter is a remote control radio designed for use in logging. It's most popular use is to remotely control the air whistle on a yarder. It is also used to remotely control the various types of skyline carriages. The handheld carriage transmitter can provide up to eight functions and voice. Shown below is the most common type of controller carried by loggers in the brush. The controllers are the two bottom devices which look like they have long, black "U-shaped" handles attached to them. The triggers that send the signals to the whistle receiver (the box). A small microphone exists in the end of the controller for voice communication.
Talkie Tooter Safety Tone transmitter signal can only be accepted by its own receiver. The Talkie Tooter receiver will only accept the signal from it's own transmitter. Talkie Tooters can be operated side by side without fear of cross signaling. This operation is achieved by interrogating every control signal that is transmitted. Two separate tones are transmitted sequentially. The first tone is a pulse of a predetermined length. This tone is identified and, if accepted, opens a circuit to allow interrogation of a second tone. If it is accepted, the control function is completed.
The Talkie Tooter transmitter will send voice messages to the receiver. This provides for the crew in emergencies and allows for situations not covered by standard whistle signals.
Shown below are examples of the new style of belt mounted controllers.
