Thread: Amplify then filter ?
face BY : Mike Kendall email (remove spam text)

There is some very interesting amateur radio work (and computer programs)
with super weak signals for VLF on the internet.  A key to it's success is
accurate frequency resolution.  From what I've read, even 1hz off can make a
difference sometimes.
