      Hi Bill,

      What I believe you're seeing is "average" power
      out. If you transmitted CW, RTTY or FM, you'd
      see 500 watts. The WSJT tones are similar to
      voice - you'll see an average power out, that may
      hit 500 watts on peak. My guess is that all is
      well. Just have fun with the contacts!
