Jukka's measurements were of a relatively clean radio compared to the 
dirtier ICOM and Yaesu models. For those dirtier rigs, keying wave-shape 
will be more significant.

Also, the average power in the sidebands is not what matters, it is the 
peak power (i.e., the transients) that causes the QRM.
