A little background: A friend asked me to setup his radio like mine, to be able to play a sound board app (noise toy) on his phone and feed it into his radio. So I disconnected his P.A. jack and wired it to the 4 pin mic jack with a bluetooth receiver out the back. Works fine, but he now wants it to operate without keying the mic (and so would I) but I never thought about installing a VOX.
I noodled on the idea for a while and wonder if its even possible without using a switch, and without making the microphone voice operated as well, or is there a better way?
VOX wiring?

Depending on the radio, either electronic or relay switching is used for rx and tx. Something has to trigger the tx switching circuit to transmit, whether its vox, or a regular 'ol ptt. Some sort of switch would have to be used...
Im not familiar with noise toys and all, how does it work currently? App on the phone sends signal via bluetooth, into the radios audio circuit, key the mic and noise toy transmits?TheDude1969 Thanks this. -
Just what we need, another moron with a noise toy to piss everyone off.

It's also easy to incorporate a store-and-forward in the "audio out" line from the, errrr, annoyance device. It's used onsome simplex repeaters and dispatch consoles so that the first couple of spoken syllables aren't lost during the PL sensing and transmit power-up & such. So it could be done, but what would the user do to sense when the, errrrr, annoyance device is needed to be activated? BTW, nice going to the OP for figuring out how to use the existing rear panel jack for a parallel input.

Thanks handlebar, but I can't take credit for the rear jack, that was H&S Electronics, I only copied his work and added the bluetooth adapter.
