[Elecraft] RF gain sweet spot

[K7WIA]

Yes I am using the K3
I was using the preamp that is in the K3,    I also have the ARR P50VD
preamp on the back of the K3 but using it just raises the background noise
to S7.
Remember I live in the city.  I can turn off the preamp that is in the K3,
disconnect the antenna listen to the hiss of the K3, and then hook the
antenna back and hear the noise increase.. i am going to try it with out
using any preamp at all...I can still detect the weak beacon that are in my
area.  and still hear a increase in noise when the antenna is connected. but
just to reduce the background noise has helped my 73 yo ears make the weak
ones stand out better.
even without the preamp on I still get the 2nd bar on the S meter to
flicker,  and  i can reduce the Rf gain just slightly ( not much) to dip the
S meter. 
just the joys of living in a big city,  powerline, and wireless headphones
on 6 meters
