[Elecraft] CW transmitting - any clicks?

[Jessie Oberreuter]

      The last time this came up, Wayne theorized that it might be the 
sound of slight mechanical adjustments in the relays as power is 
redistributed.  They aren't being switched, but the coil voltages may be 
changing slightly, inducing an audible modulation in the electrically 
shiftable parts.  Hunting it down was on his rainy day list :).
