Hello,
I am trying to interface a headset (with a PTT (Push to Talk) button attached to the headset)- to my computer.
The headset is tricky because when the PTT is open, the speaker is ON and the mic is OFF. Then when the PTT is closed the speaker is OFF and the mic is ON along with the command to tell the computer the PTT function is also ON- thus activating the computer transmitter.
The best I can figure out is to have a DPDT relay powered by the PTT (with a possible amp if needed). However, I want to stay away from a relay if I can and just use no moving parts. I'm still mastering my transistor circuits but I think my application should be possible.
Thank you!
