[Elecraft] KX3 Tuning noise

[gt-i at gmx.net]

Rick,
with PREAMP off and AGC-Fast the noise is measured as follows (peak 
values), depending on band (quiet ) and antenna:
on 10m, on a vertical: 1.1 dbV, on the beam: 1.8 dbV
on 12m, on a vertical: 3 dbV, on the beam: 2 dbV
on 12m, on a vertical: 2 dbV, on the beam: 1 dbV
To get an idea how these values are related to S-points:
S1 indicator on: ~3dbV
S2 indicator on: ~6.5 dbV
Which means if signals are well over S1 you won't hear the noise. 
However, the KX3 can well receive signals "on the edge", and then it 
becomes distracting.
