Good morning Elecrafters!

It's been some time now since the K3 LPF add-on filter board was released.
I've been contemplating purchasing one since its debut as I've noticed in
the past hi-frequency DSP artifiacts, especially when listening with
headphones.  However, as time passed and firmware improved, I don't seem to
hear so many of the things I thought I heard before.  Perhaps my hearing has
changed as well - who knows?

So, with that said - what are people's opinions now on the LPF module?  Is
it still worth the purchase?  Can a noticeable difference be heard,
particularly on SSB with the filter installed?

Finally, for those who performed the install themselves, what did you use to
cut the two traces?  Will a box cutter work or should I use a dremel cutting
wheel?

Tnx,
James
