USRP SBX board and RFX2200

GNU Radio

I wonder if SBX board can replace all RFX series including 2.4G ISM band
and
so on.

And currently I tried to use RFX2200 with GRC
but it says RFX2200 is unknown (0x002d)

How can I solve this problem?

Common dude, you have been around on this list for a while now. Post the
verbose from whatever you are running, or even better, post the output
of uhd_usrp_probe.
