Hello Rune-
Thanks for the fantastic software! I built an 11-pole 500 kHz Low Pass Chebyshev filter using AADE Filter Design software back in 2010 for use with a Softrock LF Ensemble II SDR kit. It seemed to work as expected, but with NanoVNA and NanoVNA-Saver I was finally able to do a 'proper' analysis- see the attached images. Also, thank you Hugen and edy555 for the fantastic hardware!
