Product Code: TW47
Buy Sell Sales Clear-Com TW-47

Clear-Com/RTS 2-Way Radio Interface, connects Clear-Com or RTS to any 2-way radio

Compatible with both Clear-Com and RTS®, TW-47 connects virtually any set of walkie-talkies to anyone on the wired party-line intercom; simply use one walkie-talkie as a basestation. The base-station radio is keyed from the intercom call signal. Extensive RF and EMI isolation prevents interference from entering the intercom system. Separate transmit and receive level controls are provided, along with audio level and transmitter keying indicators. The stand-alone interface is powered by the intercom line.

Note: Two-way radio must have headset and microphone jacks.
