[Elecraft] K3 Filters

[W3FPR]

Dave,

Remove the top cover - there should be a sticker either on the bottom of 
the top cover or on the top of the sub-RX showing the filters installed 
and the offsets if they are not the 8 pole filters.
If the sticker is not present (or is incorrect), then yes, you will have 
to remove the Sub-RX to see the filters in the main RX and remove the 
sub-RX cover to see the filters installed.

73,
Don W3FPR
