S9+ Noise on all bands in all modes

My radio is the 6600 running SSDR V 2.1.32. This morning the rig was working fine. I left it running and this afternoon I saw a station spotted that I wanted to work. I found that I had S9+ noise on all bands and all modes. Some strong signals were visible on the waterfall. When I disconnected the antenna the signals went away but not the S9+ noise. I have nothing connected to the radio except power and the ether net cable, still have the noise.

I have another radio which works fine with the same antenna with no noise problem.

I have shut down and restarted SSDR and I have rebooted the radio with no change.

Anything else I can try?

    Thanks Steve. Tried that but NB and WNB have no effect on the noise.

    Paul, was your reboot on the radio a factory or just turn off and on? Also ck your power supply. It could have failed.

    Thanks Roy,

    I have not done a factory reset, just shut down radio and turn off power and then restart. 

    The power supply is good.

    If a factory reset does not resolve the issue, then I think you need to open a help desk ticket..
    ( I had the same problem ).

    Me too but on a 6400M. Did a factory reset (actually several) to get it to clear. Now I have problems with my transmit audio. Not sure if it is related but I think it may be. I have a help desk ticket open already.

    My radio is back at FLex for repair. They suspect a problem in an SCU.
