    Armed now with a NanoVNA, I took a look at the passband of the 5 MHz filter
    in my Barebones Superhet (BBRX)  W4OP built it on a Circuit Board
    Specialist Board.  He put a 5 MHz CW filter in there;  I broadened the passband for phone by changing the values of the capacitors. Here is what
    the passband now looks like in the NanoVNA: This is what DeMaw would call
    an "LSB filter."  You would get much
