XiaoK radio: Manual tuning on a DSP receiver with AGC = 0, soft mute = 0, AVC = 0, SI4732*

Many don't like cheap DSP receivers for muting when being tuned manually, irritating overamplified hissing/white noise, lack of "analogue feeling". This is just to show you how the most common SI4732* chip (XiaoK receiver) works with some extras added to the frontend (at the antenna layer). I think by user experience it's not "hissing calculator", but is almost halfway to a normal decent PLL-receiver. Minimal chuffing, low hissing and varying loudness depending on the signal strength to make it feel closer to analogue. Use your headphones, if available, to hear it properly. Further optimisation is possible on the firmware and hardware level, which I wouldn't be able to make on my own.
