Re: [Discuss-gnuradio] Could this output be a problem with my Hardware or the python codes?

[Matt Ettus]

Are you trying to simultaneously transmit and receive with the 
XCVR2450?  Because it doesn't do that -- it does not do FDD.  The 
RFX-series will work in full duplex mode, but you still need to put them 
on different frequencies.

If you really need to do this with the XCVR2450, then you will need two 
of them.
