PTT/Key Cable for Flex Radios

Description

This is a 6′ breakout cable for those wishing to control PTT and Key inputs on their Flex radio with CTR2-Micro. One end has a 3.5mm (1/8″) stereo jack that plugs into the PTT/Key jack on CTR2-Micro. The cable splits into two mono cables. One mono cable is connected to the Tip of the stereo jack and has a 3.5mm stereo plug 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 that is wired to the Ring and Sleeve on the stereo connector. This plug connects to your radio’s PTT input. The provided 3.5mm-to-RCA adapter allows you to plug into the PTT RCA jack on your radio.

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.
