The xcvr2450 will work happily with gnuradio 3.2.2 and 3.3.0 (probably
earlier versions and definitely the latest git master)
Have you tried usrp_fft.py? Use a command like:
usrp_fft.py -d 16 -f 5.0GHz -R A
Have you tried it on both sides of your USRP? (change "-R A" to "-R B")
Have you tried more than just the 5.0GHz frequency? Try something in
the 2.4GHz band
Did you try both antenna ports?
Try using a Signal Generator to inject a sinusoid at 5.001GHz and
-40dBm. Can you see the sinusoid in your usrp_fft.py window?
