Clear-Com/RTS 2-Way Radio Interface (TW-47)BSW PART: TW-47

Compatible with both Clear-Com and RTS, The Clear-Com TW-47 two-way radio interface connects virtually any set of walkie-talkies to anyone on the wired party-line intercom. One walkie-talkie, working as a base-station, is keyed from the intercom call signal.
The TW-47 boasts extensive RF and EMI isolation that prevents interference from entering the intercom system. It also offers separate transmit and receive level controls, along with audio level and transmitter keying indicators. The intercom line powers the stand-alone TW-47.

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