      I just uploaded a text file to the WB4JFI files folder which adds the necessary Python code to Quisk 3.5.1 to add an audio filter bandwidth shadow to the spectrum display (in both the spectrum and waterfall display modes).

      I think the line numbers are right, or at least very close. I've only tested this in receive with my SDR-IQ and Charleston SDRs. Please let me know of any problems.

      This works OK for me under Linux. While I also have the Windows alpha version of Quick running with my SDR-IQ, I'm having some issues building the proper development environment to rebuild Quisk under Windows. These mods should work for both Linux and Windows, but I cannot test Windows right now.

      Bring back the moving coil meter? At least when the needle gets pinned to the left end stop, pronto you d realise your leads were reversed. 73 ... Sid. ... --
