Modulation in sample wav file #7

Open elektronika-ba opened 4 years ago

Hello,

Your provided sample wav file sounds like the RF signal is FSK modulated. Is that the case in your recorded sample?

I thought RKE systems use ASK (OOK).

I am probably wrong, but it does sound like FSK.

Update: Reading through articles online it seems that Japan mostly uses FSK for RKE. FSK is also used elsewhere but not as common as ASK. I guess your wav is FSK then :)

Thanks
