[Elecraft] XFIL on K3

[Don Wilhelm]

Bill,

I have never seen any restrictions like that.  If the filters are 
properly configured, that is all that counts.

It may be a bit confusing though if (say) the filters cycle from FL3 to 
FL1 to FL4 as the bandwidth is narrowed, so mmost are in fact installed 
in descending bandwidth order.

If you have the subRX installed, you will have to remove it to see the filters on the main board, and also lift the cover on the SubRX assembly to determine which filters are installed there.
