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

in this 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

in this project step by step how to build your own Concurrently Multi Channels VFOs Memory Scanner Software using GNU-RADIO Companion under Win 10 , this is not jump scanning in different frequencies ranges , its SCANNING AT THE SAME Dongle Bandwidth Range , i build in this video the principle how to make scanning VFOs memory for TWO VFOs : VFO1+ VFO2 , and you can increase it as what you like .. i make my own 13 VFOs Scanning and works well too ! its very good for monitoring NFM analog frequencies if its all closer together and at your dongle bandwidth ... we learn how to make RF Gain slider , VFO1 , VFO2 , SQL , PPM Correction , Center frequency , volume ....i use in this long tutorial 32 BLOCKS . 1:00:53 screenshots with details of all 32 steps and with how to use grid position for sliders . what Blocks i use : 1- wx gui main block 2- wx gui slider block : id=center_freq label= Center Frequency 3- variable block : id=down_rate value=250e3 4- variable block : id=samp_rate...
