Phil,
I don' t think it is necessary to have the same number of filters in each receiver. My K3 main RX has 13khz, 6khz, 2.8khz, 500hz, and 200hz filters. My subreciever has 13khz, 2.8khz and 500hz filters. This gives me great flexibility with the subreciever and saved me lots of money, without sacrificing too much performance. My configuration still allows me to do diversity receiver on SSB and CW if I desire, and performs as well as almost every other amateur rig on the market. Other might disagree, but for me, because I'm on a budget, this configuration gives me a good balance of flexibility and performance in my subreceiver.

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.
