The K3 became a different radio after the modification that I am quite
pleased with. One of the problems we have is that no one who works at K3 can
apparently hear the problem, thus no hurry or they think we are crazy.


Mike,

The problem is that meanwhile there is a lot of mix-up going on between hamradio and "hifi" enthusiasm. I've always seperated those but some don't. A lot of hamshacks are now filled with (semi) pro audio gear that is used for 10db s/nr SSB channels :-)

Because of this mix-up it is hard for Elecraft to seperate *serious* audio flaws from complaints about K3's not sounding like studio recordings.

The LPF board works wonderful in clearing out the last artifacts from DA conversion (and I think should become a regular upgrade) In the hamradio SDR/AD-DA era we encounter the same problems as in the first consumer digital audio products. This will clear out over time ;-)
The K3 has room for those improvements where other radios are "fixed" by current knowledge...
