Something I hadn’t understood - that the low pass filters as well as the band pass filters are active during receive mode…
My audio and RF sweeps attached for reference… not sure what “good” exactly looks like. Think my audio sweeps look reasonable, but the RF sweeps for 80m & 40m don’t look like low pass filters. 20m looks ok which is good as I don’t have any “wire in the sky” for any lower bands at present.
Göran> maybe useful to post pictures of you audio/RF sweeps?
