[Elecraft] K3 Subreceiver KRX3 and Filter Lineup...

[Phil Hystad]

If I were to buy the K3 subreceiver I understand that performance is best if the filters all line up and match.  That is, the filters in the main receiver should be duplicated in the subreceiver.

So, what is the downside if this is not done.  The main reason I am considering the KRX3 is for DX split operation.  I have no plans (now or likely in future) for other specialized uses such as diversity reception.

My main operation is CW and so in addition to the standard 2.7 KHz filter, I would like to only buy my 400 and 200 Hz filters.  My main receiver from the top down are:  6.0 KHz, 2.7 KHz, 1.8 KHz, 400 Hz, 200 Hz (actually, the 200 Hz is on order).

Are filters expected to be in the same positional slots for both receivers?

Thanks for the help.
