Hello  LF'ers

Is anyone able and willing to advise on my band pass RX filter design
please? I have made a band pass filter for 137kHz reception and
checked it with my SDR in real time. It is shifted a little high and I
am wondering what I need to change to pull it a bit lower? Any
practical advice or component values welcome. Adjustability would be
nice! Thanks

Filter design is at http://www.chriswilson.tv/lf-circuit.jpg
