This weekend i took out of the box my limesdr ( i bought 1 year ago and i didnt use it since then), and i followed the quick guide in order to get my limesdr working in my windows pc.

I got 2 issues:

and

this one:

About the second one , i tryed to transmit an AM modulated 3khz tone at 60MSPS using a simple flowgraph in GNURadio. The issue dissapears when i reduce the sample rate bellow ~ 43 MSPS. To visualize the limesdr output i connected a coax cable from limesdr output to a rtlsdr.  
To connect the limesdr to my windows machine i use a 1.8 meter usb 3.0 extender.  
Can it be related with my first problem?
