GNU-RADIO Scanner

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...
