Hi all, I have been following this thread with interest. My experience is that my K3 seems noisy at home where my ambient RF noise floor can be anything up to s9 at times with the amount of RF producing electrical junk all around me. However, when I use it at a 'quiet' location such as our DXpedition to the Isle of Jura or our contest site, the RX is extremely quiet. This leads me to believe that I am simply suffering from a RX with a *lot* of gain. At home, I simply turn down the RF gain and it is amazing how quickly the noise lowers significantly! There is only about 30dB of isolation between antenna 1 and antenna 2 off the tuner which does not help the noise floor and as such I have simply stopped putting an antenna in ant2 for HF, I only have my 6m log periodic in there. I think in a lot of ways we are chasing our tails here.
