I didn't bother about paying/asking for matched default filters for my KRX3.
The one in the main board has a -0.93kHz offset and the one in the KRX3 is
-0.83kHz.
Shifting them both to -0.88kHz seems to make no difference to performance -
would you expect a 50Hz shift in a nominal -6dB b/w of
Stewart,
You are correct that the importance of the offset is inversely
proportional to the filter width. A 50 Hz shift not make much
difference with the 2.7 or 2.8 kHz width, but it certainly will make a
big difference at a 200 Hz width.

I received the KRX3 and the DVR today and am about to upgrade my k3. I am
using the 2.7 if roofing filter in the main unit and requested and paid for
a matching filter for the sub receiver.
The main receiver offset is -.97 but the new 2.k filter is marked -.93.
My question is are these a match

Hi,
The main receiver offset is -.97 but the new 2.k filter is marked -.93.
My question is are these a match or did I get the wrong part?
Doesn't sound like it. I'd double check with Elecraft if I were you.

I think you may have received the wrong filter. At this point, I'd
install the new filter in the KRX3, but set the Main and KRX3 offsets to
-0.95 (split the

install the new filter in the KRX3, but set the Main and KRX3 offsets
, set them both to -0.95. This
results in a worse case center offset of 20 Hz, which is not detectable. :-)

Shows what I know. The matching spec is to within 40 Hz, so you in fact
received the correct filter.
