[Elecraft] 160m noise

[Mikael Larsmark]

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.


I also tried to do a factory reset but behavior remains.
Any idea what this can be?
