The Fifi SDR can be controlled using the same API as a Softrock so I've started work on a native MacOS app that can control the frequency, bandwidth, demodulation mode and play through the audio. It's pretty rough so far but looks like this:
The code is based on rockprog and Apples AVRecorder sample.
So with just the Fifi box and this software you have a simple radio that tunes all of HF and plays through your Mac's audio. If you want the full, waterfall style, experience then I recommend DSP Radio which also supports Fifi.
You can download the alpha app here. As I haven't signed it you will need to right click (control click) and choose Open the first time to open it.
Be careful not to choose built-in audio from the input device and turn up the volume or you'll get feedback. Speaking of feedback, let me know if you find this useful.
Build 2 has the following improvements:
- Automatically selects the FiFi audio device if found
- A button to set the frequency directly
- A tuning slider - I'm still experimenting to get this working nicely.
On my device anyway, the frequency is off. I'll have to look at how to fix this.
