[Elecraft] K2 build bargraph question

[Paul Huff]

I have completed part II of the assembly of my K2 and I am about to move on to 
part III (alignment and testing of the 4 MHz oscillator, VCO, BFO, etc.). 
Everything has gone well up to this point but I did notice something that seems 
a little bit unusual.  Is it normal for my bargraph to light up it's segments 
from minimum to maximum as I turn the RF gain control from maximum to minimum? 
At the same time the hiss in my earphone drops to nothing.  No antenna is 
currently connected to the radio.

Thanks in advance for any replies!
