FM2TXT Files

Unpack software archive into some folder, e.g. C:\fm2txt

Go to https://www.anaconda.com/download/ and choose Python 3.6 version, 64-Bit Graphical Installer
or download directly: https://repo.continuum.io/archive/Anaconda3-5.0.1-Windows-x86_64.exe

Run anaconda prompt, change dir to C:\fm2txt [c:] [cd \fm2txt], then run: pip install -r requirements.txt

Last step is to copy 2 files from x64!!! osmocom rtl-sdr drivers: https://osmocom.org/attachments/download/2242/RelWithDebInfo.zip
Copy these [rtl-sdr-release/x64/]: rtlsdr.dll & libusb-1.0.dll into C:\Windows folder.

Now we may run, this will produce text recognition results file [radio_log.txt]:
python listen.py --freq=95000000 --gain=20 --ppm=56 --lang=ru-RU

Some unnecessary help available:
python listen.py --help

To mute audio output use verbose key:
python listen.py --verbose 1
