Hi - you should go through the tutorials at https://greatscottgadgets.com/sdr
regarding the use the HackRF to receive WBFM - i.e., how to avoid the DC offset. You should turn off your RF gain - use IF and BB gains for receiving - turning on the RF gain on the HackRF runs the risk and smoking your RF amplifier All the above issues are discussed Michael Ossmann's great set of videos at the above URL. Also, in your grc file, the quadrature rate is 200k, the re-sampler is set to interpolate at 48 and decimate at 20 which means the sampling rate at the audio sink is 480k - not 48k. The sampling rate at the audio card needs to drop to 48k. -- Cinaed On 09/29/2016 09:15 PM, Kavyashree wrote: > Hii > > Thank you for your response. > > 1.
