Transmit and receive images on gnu radio using FMCOMMS3


i have this project that i want to send a jpg image using gnu radio and fmcomms3.

Without the hardware, if i do the encode-modulate-demodulate-decode step, i can send and receive images without a problem.

To test if i can send and receive signals i used the 'cyclic-sine' example and it works.

but when it comes sending the images using the setup below, i could not receive anything,

any thoughts or hints on what could be going wrong? 

Thanks in advance,
