That Elecraft is testing the filters now is a good thing!
I remember a post from Elecraft a few months ago, that said that I
should not use the 8.2M IF filters that were intended for Yaesu's FT1K
because the filters for the Elecraft K3 were specially selected to get
top performance.

Are you in PA NOR or in PAIO NOR?
You need to be in PA NOR to enable high power.

I was waiting and waiting for the K3 and ended up buying a Yaesu

Originally all 8 pole filters were supposed to be 100% tested at INRAD's
supplier. When we discovered some bad ones had gotten through, we added
100% testing at Elecraft and at INRAD in Aptos.

I agree with Jim . A fast tuning rate on AM is not necessarily good.
What is good is to be able to vary the rate to fit what the user likes .
Like the FT-817 and IC-746.
And, Jim, being a live OF beats the heck out of the alternative!

AFX provides a delay between the two channels.

Well, at least one reason is that some SW stations still insist on using
frequencies other than precisely on the 0 or 5 kHz marks. Also, a
slower tuning rate makes it easier to "offset" the tuning to one side a
bit to help duck interference. This is the "we don't need no stinkin'

Yes.
In data mode, the intent is to have as pure a signal as possible, so AN

A mode then TxEQ should also be set to flat.

I'd keep the K2/10 with the KAT2. That's a nice tuner and can't be used with
the PA. The only other option in the qrp rig you don't have for the qro is
the K60RX. Might be better to move that than to waste the KAT2.

Don't expect to see any -firm- word on this for a while. Once the KRX3 is in
routine production, the 'brain-trust' will turn it's attention toward this
one. Perhaps by the Fall contest season? Should be much less of a design
