[Elecraft] New K3 Receive question

[Fred Jensen]

Did you calibrate the S-meter?

What mode is the S-meter in?  In ABS mode it displays the actual input 
signal level [if calibrated to 50uV=S9] regardless of preamp status. 
Otherwise, activating the preamp will raise the S-meter by the preamp 
gain.  Or, maybe it's the other way around, I can never remember. :-)

With the preamp off, does the noise decrease when you disconnect the 
antenna?  Easy way to do that is switch to ANT 2.  If it does, you don't 
need the preamp.

Side-by-side on same antenna, my K2 sounds like, and the S-meter closely 
follows, the K3.  Both are very quiet until I find a signal.
