[TenTec] My Orion - qsk

[Carl Moreschi]

Tommy,

Thanks for the excellent explanation of high speed CW operation and what QSK
really means at those speeds.  My CW maxes out at around 35 wpm.  You gave
me a lot of insight on really high speed copying.  I assume at some speed to
start to hear words and not even individual letters anymore.

73,
