K3S Problem with Filters

[Elecraft mailing list]

I have recently fitted a Sub Receiver & some additional filters to my new to
me K3S. I now have in the main RX, a 6K for AM, a 2.8K, 2.1K, 0.4K & 0.25K.
In the sub RX there is a 2.8K, 2.1K, 0.7K, 0.4K & 0.25K. I have a problem
with the 0.4K filter position in both receivers. Between about 0.45 & 0.35
in both receivers there is an immediate drop in volume, still copyable but
not working correctly.

Does anyone have any ideas what the problem may be?

Ray,

You can set the gain parameter (FLxGN) parameter in the menu to
compensate for that.  Either use K3 Utility or set it manually in the
CONFIG menu.

My two narrowest filters have CONFIG -> FLx GN set to 6dB as opposed to
0dB for the others. Press the number keypad to select the appropriate
filter.
