Cobra 25 and 29: Adding talkback


Cobra CB models 25 and 29 (all versions)

DESCRIPTION: Adding talkback

ACTION: Talkback can be easily added to these radios by installing a resistor from the

sleeve of the external speaker connector to ground. See picture of the location.

Adding a resistor will give a fixed audio level on the talkback. Try starting with a 100 ohm resistor, and adjust as needed for the desired volume level.

If an adjustable talkback level is desired, a potentiometer can be used in place of the resistor. A 200 ohm potentiometer is recommended.


NOTES: None.
