[Elecraft] Elecraft CW Net Report

  Good Evening, Conditions were poor on both bands.  Forty meters had a few storms with medium to deep QSB.  I am gradually learning how to control the single lever paddle.  If I can maintain a decent rhythm my mind doesn't switch to thinking about mechanics.  If I think word after word they
