I use the raw output on the computer screen, that is seeing all the
noise there. If nessary I lowpass filter the psn files down to 4Hz or
whatever I need. But my online plots are filtered at 4Hz.
To detect local activite at ~320 km you need to increase the amplifeing
on your winsdr board (removing the jumpers to start with). That is what
I did and that did improve the resaults and what I was detecting
earthquake wise. That did also enable me to record teleseismic
earthquakes with 4.5Hz geophone, but only really large one, mostly
earthquakes above mag 6.0+ at size. But it is location dependent for me
and problay is for you too.
I also recommend a screened cable or some form of properly ground
connected cable, in order to prevent electronic interferance in your
I hope that this can help you something.
