Trying to get 7Mhz people communicating but unfortunately getting radio stations :
Not the issue for now..The receiver : antenna to bandpass filter then through Rf amp
Between the filter (for 50 ohm output ) and Rf amp (50 0hm input) is the problem
There's a cable linking the filter to amp input (coupling) capacitor (100nF). My hand has to be touching this cable for there to be sound at the end
Problem is clear??
Please how to fix?
Thanks
