[Elecraft] K3: PRE/ATT Bug or feature?

[The Smiths]

This is NOT a bug, this is working EXACTLY as it should.  Some time you want to have a little extra gain, but not as much as the Pre does alone.  In this case you will run the Pre ON, and the ATT on at the same time.  No bug there.  Just another way Elecraft has made the K3 a versatile rig for finding weak signals in a loud noise floor.

> My K3 (SN 1069, fw 4.03) has always exhibited the ability to have PRE and ATT on simultaneously. If one engages ATT by a long hold, then hits PRE with a tap (same button), the display shows both functions engaged. The converse is true too, i.e. PRE engaged with a tap, followed by ATT with a long hold.
> 
> Signal levels by ear and S-meter seem to indicate both features are on simultaneously. The appropriate length hold will turn one feature off, as indicated by the display. Levels change accordingly.
> 
> Is this a bug, or an undocumented feature? The feature(s) being a PRE function with less gain or a ATT with less attenuation.
