Odpowiedź na ile miarodajne mniej więcej masz w samym logu :
- przy sprężynce radio wyzwoliło się 38x
- przy antenie 50x.
Co do dongla…
rtl433.zip (2,5 MB)
Rozpakuj sobie, podłącz dongla z anteną do USB, PC/Laptop/CMD…
rtl_433-rtlsdr.exe -f 868.95M -s 1200k -R 0 -A -vvv
Efekt mniej więcej ( czyli czy dongiel słyszy cokolwiek na 868.950) :
