Build Advance NFM SCOPE Receiver with real time Recorder GNU-RADIO Win10

in this video tutorial step by step how to build and run Advance NFM SCOPE Receiver with real time Recorder under GNU-RADIO Win10 , i use 38 blocks . This based on ham2mon with adding center frequency entry . 01:13:19 screen shots step by step with full details . Blocks i use : 1- qt gui main block 2- qt gui range block : demod_bb_freq 3- low-pass filter taps block 4- low-pass filter taps block 5- low-pass filter taps block 6- qt gui range block : center_freq 7- qt gui range block : squelch_db 8- qt gui range block : gain_db 9- variable block : file_name 10- variable block : samp_ratio 11- variable block : final_rate value : samp_rate/initial_decim**2/int(samp_rate/1E6) 12- variable block : initial_decim 13- variable block : samp_rate 14- variable block : fft_length value : 256 * int(pow(2, np.ceil(np.log(samp_ratio)/np.log(2)))) 15- variable block : final_decim 16- import block 17- osmocom source block 18- qt gui frequency sink block : name= Spectrum MWK 19- stream to vector block 20- Keep 1 in N block N= int(round(samp_rate/fft_length/1000)) 21- FFT block window= window.blackmanharris(fft_length) 22- complex to Mag*2 block 23- integrate block 24- Log10 block 25- probe signal vector block 26- vector to stream block 27- qt gui time sink block : name= Average Spectrum MWK 28- frequency xlating fir filter block taps= variable_low_pass_filter_taps_0 29- decimating fir filter block 30- decimating fir filter block 31- qt gui frequency sink block : name= Decimated Channel MWK 32- power squelch block 33- quadrature demod block 34- decimating fir filter 35- polyphase arbitrary resampler block 36- power squelch block 37- Wav file sink block 38- audio sink block Based on Reference ham2mon https://github.com/EntropyWorks/ham2mon ---------------------------------------------- MWK@2020 ---------------------------------------------------
