[Elecraft] [K2] Filters attenuation

[Petr Ourednik]

Dave,

yes I am confirming > it is the attenuation which I am talking about...
When I am decreasing BW from 1.5k to 700Hz there is not noticeable att
(which means it's aprox. less then 3dB) but by going to 400Hz or even to
200Hz I hear big att which can be like You said 8dB or so.

Anybody else has similar experiences pls?
