I sincerely hope that the small filter board
I'm not complaining about not updating and I think it's a reasonable
price, per-se. But add in the postage, customs handling (no duty) and
VAT, this gets a little steep over here and I can't really afford to
do that for some performance I might not miss.
YMMV
And I'm not suggesting this

I sincerely hope that the small filter board will be available for those of
us without the newer DSP board. I will not be getting the newer board, I
can think of other
I am anxious to see what the new board will do. I have used QF1A for many
years and never found a radio yet where it did not enable me to copy signals
much better. I treat my QF1As like gold and never operate without one in
the Peak mode.

Does the DSP Board swap change anything other than the audio chain, and is
that for headphones only?

All the board changes do is improve
One doesn't have to be a Hi-Fi enthusiast to be discomforted or fatigued by
distortion products and other artifacts, but perhaps being one is useful in
knowing the causes. Not perceiving these in the conscious mind or otherwise
quantifying or qualifying them does not mean that a person is

I have one of the upgraded boards.
Mine is a rev B with some SMT component changes that achieves approximately the
same result as W9AC's bass extension mods, although Elecraft seem not to have
changed some of the capacitor values. I think I read somewhere they were
achieving the same result

I have two K3s, one has the new DSP board, so I hooked them up together and
listened to low frequency tones. The higher SN radio definitely has more
bass. In fact I have noted a few times, just how low it goes. It seemed very
unusual
Well I for one missed the AF filter part of the DSP upgrade.
Not all K3 owners spend time on the internet and Elecraft web site in
particular.
So if anyone does know exactly what the AF filter does to enhance the receiver
DSP over that what we have prior to it's release, would certainly help
