Re: 12V Power for the Pi (was Re: [RaspberryPi-4-HamRadio] Getting back to the RPi)
It’s always been my understanding it’s not the transformers that are the problem, it’s where the audio is injected—if it’s injected in the mic input then you are limited to 1200 baud, but if you inject elsewhere (the IF? I can’t remember) the you can get 9k6. A lot of modern radios have inputs for data that take 9k6. I think any soundcard can connect to those inputs for higher baud rates via direwolf. The signalink and other specialized cards I think have optical isolators that isolate from the computer. ‘Course it is NYE, and I could be all wrong due to that.toggle quoted messageShow quoted text
