LimeSDR-USB Transmit with gr-limesdr

@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
  3. I installed gr-limesdr from here: https://github.com/myriadrf/gr-limesdr
  4. I started GNU Radio and ran two_tone.grc
  5. I get the same picture as I did on my Ubuntu computer:
    20180621_windows

EDIT: I removed the USB 2.0 extension cable I was using and now the picture looks correct:
20180621_windows_USB3

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.
