Exactly what I needed to know. I do plan to add the P3.

Thanks!

The main value is bringing the IF output up to a level that is usable
by the P3.

I thought that the mod was in all K3's after s/n 3600-something or
other, but there are probably experts around (or Elecraft crew) that
know the exact cut-in s/n or date.
