[test] DSP radio manual tuning on SW + anti-EMI/low-noise antenna

1. An SI4732*-based receiver allowing for manual tuning at 1 kHz step (soft mute=OFF, AGC=ON, AVC=OFF, BW=6k). 2. A frame loop antenna (4x75 cm, 3 layers connected in parallel), RF-transformer (1:9, decoupled) + LNA-TQP3M* + FM bandstop filter. City residential area with heavy EMI. The time is 19:30 (EEST/local).
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.
Further optimisation is possible on the firmware and hardware level, which I wouldn't be able to make on my own.

Well you're not in Turkey any more 😅 10:15
