@Zack  
I still get the same result with new software, and on a different computer.

So here are the versions of software that I’m using

1. I’m on a Intel Core i5 running Windows 7 Professional (64 bit)  
a) I uninstalled Pothos and GNU Radio and rebooted.  
b) The windows driver hasn’t changed in git, so I didn’t re-install that.  
c) I programmed the 18.06 firmware yesterday with this version of LimeSutie: LimeSuiteGUI\_20180613\_1cb1723.exe
2. I installed GNU Radio (gnuradio\_3.7.12\_win64.msi) from here [http://www.gcndevelopment.com/gnuradio/downloads.htm](http://www.gcndevelopment.com/gnuradio/downloads.htm)
3. I installed gr-limesdr from here: [GitHub - myriadrf/gr-limesdr: gr-limesdr Plugin for GNURadio](https://github.com/myriadrf/gr-limesdr)
4. I started GNU Radio and ran [two\_tone.grc](https://onedrive.live.com/?authkey=%21AOG9_4m186ktP0g&cid=C212FD8760DDD7C4&id=C212FD8760DDD7C4%21936&parId=C212FD8760DDD7C4%21935&o=OneUp)
5. I get the same picture as I did on my Ubuntu computer:

EDIT: I removed the USB 2.0 extension cable I was using and now the picture looks correct:

It was not just the cable because plugging the LimeSDR-USB directly into the USB 2.0 port gave me the same picture as the pictures with the USB 2.0 extension cable. All pictures, except the one where I said that I removed the USB 2.0 extension cable, were using the cable; this cable was used for taking the self test pictures in my previous posts.
