VCO Too High Error

Hello all,

I have ran this flowgraph to send a cosine signal and receive with our LimeSDR. I have the SDR connected to a external power supply and running gnuradio on a Linux computer.
I am using this flowgraph.

We are getting this error below. (I took out the part where it shows the files etc)

Traceback (most recent call last):

Done (return code 1)

How do I change the VCO on gnuradio?

@andrewback Any idea for this error I am receiving?

Error message indicates that Rx filter calibration fails. Try using higher filter bandwidth (e.g. 5 MHz instead of 1.4 MHz).
