1. Please take a look at the FAQ, section ExpertSDR2, questions# 6. 9.
2. What are the noise floor and S-meter values without antenna?

Hi Roman
I take a look @ FAQ on point #6 and #9 and done some test playing with Attenuation and other feature :
Without antenna in the connector i see this values:
the lowerest signal i obtain with "Front and Preamp" on and with 0 Db Attenuation level : S6 with -92.1dbm
with still "front and preamp" on but with -20Db attenuation : S9 with -74.7 dbm
Simple Rate is 312 Khz
Nb : antenna is ALA 1530

Many thanks for Help

Do you have a signal generator with a known signal?
Can you apply this signal on the receiver and compare it with what you see in the software.

Just did the upgrade to Version 1.3.1 Update 7. Seems OK until it asked me to upgrade the Firmware. Now the S-Meter is reading 20dB with 50microvolt in.
Before firmware update, baseline (no antenna) s meter read about S-1 no4 reads S-5.

Usually unless they have sent you a new file or made a comment directly to you

It means the issues has been resolved in the next release- so look at the next release (or perhaps check your current version and compare to what is posted on the site)

then usually I like to report back to GitHub as confirmed or still exits etc.
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.
