As noted on our orde form, our matched offset filter spec is to within 40 Hz or
less, since our 5 pole crystals can vary in center frequency from batch to
batch.
Set the offset for the two filters identically to the nearest 10 Hz value half
way between the two offset values. In your case, set them both to -0.95. This
results in a worse case center offset of 20 Hz, which is not detectable. :-)

Subject: [Elecraft] k3 matching filters
To: <elecraft@mailman.qth.net>
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 or did I get the wrong part?
I would like to know before I install things because I would like not to have
to redo the installation if the part is wrong.
