What panadapter noise floor reading are the SunSDR2-DX users seeing with a disconnected antenna and +10 dB preamp engaged?

My SunSDR2-Pro shows about -128 dBm on all HF bands and -138 dBm on 2m.

Hi Paul,

on HF the value is the same (-128 dBm) but on 2m it is about -131 dBm.

My noise floor on the panadapter is running -140 dBm on HF and -138 on 2M.
Using the vertical scale on the far left side of the display.
Using the sliding scale on the S-meter its approx. -120 dBm on HF and -116 on 6 & 2 M.
