RSP duo more noise vs. RSP2

Hi all,

I have a RSP2 and RSP duo, connected to a magnetic loop (antenna amplifier from LZ1AQ: AAA-1B) and a SIMWA (similar to mini whip) antenna from DL4ZAO.
If I connect both Antennas to the RSP duo (only 50 Ohm inputs), there is much more noisy on both antenna than connected to the RSP2 (broadcast band from 49m to 19m).
I have tested several times, but always the same result.
I try to put a 50 Ohms 1:1 transformer between antenna and RSP duo, same result.

Any Idea?

The Tech_support found the reason:
After uninstall SDRUno, reboot the PC, install a fresh V1.32 and reset to default settings is all o.k.
