Just wondering.
Is it normal that even without antenna the signal does not go below S3 or around -111.7dbm ?
I am using ESDR3 0.12.1
Thanks for your help

YES, a true direct sampling SDR will always have / show a noise figure
you notice if you engage the preamps the noise floor without antenna will decrease as well again this is correct
it is created from the components
Please do not email me and ask for help I no longer will be part of this, If I could delete /remove my profile I would do so.
Regarding the S5 S-Meter reading, one of the best explanations I've seen is on the Flex site.
Back before I upgraded to the Dx, my 6600M did this and I also asked the same question.
