When testing in SDR#, the noise floor value (assumed dBm) does not show the same value as compared to the values shown in HDSDR, SDR-Console and SDRUNO.
The same RTL-SDR dongle and antenna where used for all programs tested, with the exception of SDRUNO which used the SDRPlay RSP1A.
SDR#
HDSDR
SDR-Console
SDRUNO
Should be noted, even when the SDRPlay RSP1A is used in SDR#, it shows the same elevated noise floor value.
I have seen a video of an old SDR# (v0.0.0.0) showing values similar to HDSDR, SDR-Console and SDRUNO.
Does anyone know why it has changed from been similar to other SDR programs to been different?
Is this value something other the dBm?
