Eric, Thanks for your response.
Since I sent my last email, I've checked this out some more and what I find is that the click occurs on every 1 kHz step with Spur Reduction OFF and every 3 kHz with Spur Reduction ON. If I reduce the step to 100 Hz it happens at those same frequency intervals. So, it's definitely not coming from the mouse wheel but seems to be connected with the DDS? The effect is frequency dependent, but my observation of it becoming noticeable above 24 MHz was probably related to atmospheric noise levels. With no antenna, the clicks become noticeable above about 7 MHz, but are not audible below that. They occur with all mode and filter settings (though the actual sound is modified somewhat).
