[Elecraft] K2 Filter settings

[Nick Henwood]

Thrilled to get my K2 working on 7 MHz receive but I seem to have a problem with filter settings.
Everything has checked out according to the book - no problems at all (even my home-wound coils seem to work!!)
I have set up the filters exactly according to pages 88 and 89. On Filter 1 the rx sounds great - plenty of gain, clean signals. On the other 3 filters it sounds like I am listening through a dense fog - I can tell the bandwidth is far narrower than F1 but signals are weak and it sounds as if the filters are overlapping each other (if you know what I mean). I have checked settings again and all look OK. Does anyone recognise this problem please? I am reluctant to proceed until I have sorted it out.
