KX3 AF/RF gain control

[Rick Dettinger-3]

In the photo of the KX3, the gain control is labeled AF/RF.  Since  
this is not a concentric control, it must adjust the gain at both  
stages with one knob.  I am wondering if we will be able to change the  
balance of the effect that this control has on the two stages.  With  
superhet designs, my thinking has always been to set the AF control to  
match the requirements of the speaker or headphones and use the RF  
control to adjust for changes in signal strength, but I have no  
experience with DC radios.  The KX3 seems to be a very big step up in  
the design of DC radios, so I would like to see what others think on  
this subject.

Rick,

You tap to toggle the control between RF Gain and AF Gain.

"Tap" and "Hold".  After 11 years with Elecraft radios, I might have  
figured that one out!
