Forum Post: RE: CC1101 and ASK/OOK

Hi,

I have followed your advice and it works :)

I increased the rx filter bw and lowered the tx power and here comes my signal !

Thanks a lot : great chip, great support !

Here below my settings. Maybe it can help others to send/receive with ASK/OOK modulation at 433 FR.
