Dar Soarele nu emite un semnal modulat ca un post de radio.

P.S.
Totusi munca cu SDR-uri ieftine nu va aduce nici un fel de satisfactie. SDR-urile iefine sunt incredibil de slabe la sensibilitate, iar cele cu adevarat sensibile sunt incredibil de scumpe.

Vezi si niste masuratori:

Sensitivity
Both dongles have a very high sensitivity. Between about 50 and 450MHz the E4000 is about 5dB better than the R820 (-139dBm vs -134dBm). At 1000MHz the E4000 is about 8dB less sensitive (-129dBm vs -137dBm).

Alea nu-s chiar sensibilitati slabe si nici incredibil de scumpe.
