RF Transceiver

Hey I have a SAPI application that works great locally. Input via the microphone and output using TTS all work great sitting in front of the PC. What I'd like to do is operate this application remotely, via a walkie-talkie. Do any of you know if a device exists that could plug into my sound card and receive transmissions and pipe the audio into the mike jack, and take speaker output and transmit it via RF to the walkie-talkie? I don't even know what that sort of device would be called, so I can't search for it. Any advice appreciated. Thanks. Sean

Nice idea but it as a large flaw. How is the remote machine going to "Push to Talk"? WT's normally can only receive or transmit at any one time, not both at the same time. I'm sure you'll find some hardware to do it using a full duplex WT, but there remains the issue of having the machine "Push to talk". Or do you want it to transmit continuously, even if the machine has nothing to "say"?

Yeah, I know. I can't help but think this has been solved already though.

I didn't think walkie-talkies could be full duplex since the mike is so close to the speaker (I imagine a headset type device could be), but I don't really care whether it transmits continuously, as long as it can listen at the same time (full duplex, like you say). Any idea what that hardware would be called? I'd even settle for a one-way conversation. A device that converted radio to audio and piped it into the mike jack of the sound card. Thanks again. Sean

Yeah, by custom hardware. You're most assuredly not going to plug a WT's linein and lineout to a sound card and get away with this. This would be some kind of hardware that would interface with the radio and then plug into the PC somehow. I'd be willing to bet you'd find something like this around the HAM Radio crowd, or possibly even the manufacturer of the radios.

Actually, you could always use "Lego Mindstorms" or a similar kit to rig something up that physically presses the talk-button on your radio whenever the computer raises a flag. Actually, a Servo might just do the trick.

Possibly, but the question then becomes "are the parts going to last for the life of the application?"
