PTT/Key Cable

Description

This is a 6′ breakout cable for those wishing to connect the PTT and Key output from their CTR2-Micro to their radio. One end has a 3.5mm (1/8″) stereo jack that connects to the PTT/Key jack on CTR2-Micro. The cable splits into two mono cables. One mono cable is connected to the Tip and Sleeve of the stereo jack and has a 3.5mm stereo jack with only the Tip and Sleeve wired. This cable connects to your radio’s Key input jack. The other mono cable has a red 3.5mm  mono plug wired to the Ring and Sleeve on the stereo connector. This plug connects to your radio’s PTT input. A 3.5mm inline jack is provided. You will need to wire this jack to the connector on your radio that has the PTT Input signal.

If you only need to control the Key input on your radio you can use a standard 3.5mm stereo jumper cable instead. You can order that cable here.
