Mikael,
I would suggest you try 2 things - first connect a dummy load instead
of the open antenna connector.
Second, leaving the dummy load in place, power the receiver from a
battery to see if the higher noise is being caused by your power supply.
If neither of those things make a difference, contact supp...@elecraft.com.

Hi,
I am having an issue which confuses me quite a bit. When I unplug my antennas
and listen to 80m for example I have very low noise and the S-meter does not
light up a single bar. When I go to 160m and do the same thing I have S3-S4 and
I can hear a much higher noise level. It is the same behavior regardless if I
use the RX antenna or the ANT1 jack (none with any antenna). I have the same
settings on both bands.
