The KRX3 comes with a 2.7 KHz filter ... you can get by by "splitting
the difference" in the offset between the 2.7 in your K3 and the new
2.7 in the KRX3.

Since you are used to the 400 Hz for CW and possibly RTTY, I'd put one
in the KRX2 but you can probably get by without the second 1.8 KHz
filter - particularly since you do not intend to do any "diversity"
receive.

It's been a while since I researched filters, but if I recall, it is only the 5-pole that has an "offset" that needs to be matched, correct?  Is it overkill to add the other two 8-pole filters if I'm just using the KRX3 to chase DX working split?
