K2 build bargraph question

[Paul Huff-3]

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!

Paul,

That is in fact perfectly normal.  The reason is that the AGC and RF
Gain control are using the same voltage to control the gain, and the
S-meter responds to that voltage.   You will do the initial S-meter
adjustment during your Part II alignment.
