  • Ok so following my last port I have done a bit more research and work on the electronics. I have figured out that I should split the circuit into the following main parts: Power - Pull power from SWB on radio, or maybe if this does not work then from a battery. Speaker mixer - A OpAmp based inverting mixer will be used to mix all sound sources feeding into the headset.

  • When growing up I used to do a lot of stuff with electronics. Back then, mostly basic stuff, integrating different SoC’s or IC’s that are already pre-made. I also did do a fair bit of micro-controller work, mostly with the Arduino ATMega chips. Recently, I have been itching to get another project started, and what else than to do some electronics surrounding radio communications. I also wanted an opportunity to “produce” a product - that is, I want to build something that is a bit more polished that the perfboard creations of my past.
