[CQ-Contest] [YCCC] Key Clicks in ARRL DX CW

Tue Feb 23 09:49:22 EST 2016

Which raises the point, why do manufacturers allow a setting that will knowingly cause interference? If they provide the setting, and know what it does because they have implemented it, can't they tell how fast is too fast? Is there ever a reason to have such a fast rise time? Does anyone actually run 60 wpm CW these days?
