[Elecraft] Regarding the K3 and high QRN levels

I understand NB 'width' and 'depth' controls (for lack of
better terms) on other radios, so I know what's happening as
I adjust them.

I am, however, confounded by the K3 settings - which one is
'wider'?, which one is 'deeper'? Increased or decreased
effect with advancing numbers?
Am I overooking something in the manual?
An explanation would relieve some of my frustration with the
K3. 

Then we can work on the keyed PTT and the reverse CW.
