A lot of fun, especially hearing my old novice call KN1VKW and then my old General call K1VKW from 50 years ago be sent back to me.  Used my keys I had as a Novice and General from the early 60ies.  A couple of QSOs with my junk box 6 W QRP tube rig, every component (resistors, caps, tubes, chassis etc) recovered from old stuff.   Must confess I also made several QSO's with my K2.   A lot of fun.  73, Steve K4JPN
