In the expanded test reports available to ARRL members on their Web site,
ARRL now provides a frequency spectrum of the keying sidebands for a string
of dits at 60wpm as part of their routine testing.

Why does the ARRL lab judge key click
performance by observing keyed waveforms in the time domain? It is very
difficult to draw any meaningful conclusions from time domain measurements
without performing an accurate FFT
Maybe someone in the US would like to pass this on to the ARRL?
