This is for the K3.  The K3S has a different preamp setup so the numbers 
should be scaled accordingly.

With the preamp off, the gain from the K3 antenna to the IF output is 
approximately -6 to -7 dB, depending on band and on the particular K3. 
With preamp on, the gain from antenna to IF out is approximately +4 to 
+5 dB.

That assumes it is not an older K3 that has not had the IF output 
modification performed.  In that case, subtract about 10 dB from both 
gain figures.
