      Hi George,

      CW speed calibration in MR is based on the PARIS system. At 12 WPM the dot
      duration is exactly 100 ms, at 24 WPM it is 50 ms, etc. I verified the
      accuracy of calibration by measuring the duration of the message of known
      length.

      I am not sure what speed scale is used in N1MM Logger.
