Hi, I have made a unsuccesfull attempt to modify the NFM demodulator to make it work for NOAA satellites @137 Mhz. I need to change the bandwidth to 36Khz to receive the APT signal and route it to WXtoImg. change the (csdr fir_decimate_cc 72 0.005 HAMMING) Do have someone have any tips, to make it work?

cheers!

My location is in the Netherlands but I have take OpenWebRX offline. In meanwhile I have been switch to ShinySDR, (also A webbased radio for RTL-SDR )there is more support.Now I have been able to receive the APT signals for Polar orbiting satellites. You can simple add a Modulator for APT Signals. but unfortunately here is no support for the Raspberry Pi, its runs on fine on Intel platforms like quadcore with 1Gb of ram.
