I am creating a radio receiver to pick up "walkie talkie" chatter.
success it works fine! I can hear people when they speak on the radio, the only problem i am having is that when no one is speaking the static is insane!
There is very little to no static when someone is talking but there is more than my ears can bear.
So my question: How can I filter out the interference when the radio is "idle" from the image its clear to see I have a very high center frequency (which is just silence and constant)
and then I have some "static" between -70 and -80 db, when there is radio chatter the db jump above -60, so I am guessing I need to filter out everything lower?
I am very new to this any guidance on how and what to do would be appreciated.
