Flatness of the KiwiSDR frequency response

While flatness of the KiwiSDR frequency response has cropped up a few times within the wsprdaemon noise graphs topic, I can't find an explanation of why the response has the repeatable shape shown in the graph below, three units tested by Glenn, N6GN, and one by me.

With Glenn and Rob I'm writing an article on wsprdaemon noise measurement and would really like to nail the cause of this response - it is not simply the LPF, from Glenn's measurements.
