I have two TwinRX daughter cards plugged in to a X310.
AGC has three settings: Default, Enabled, and Disabled.
When set to Enabled or Disabled, I get an error.
self.uhd_usrp_source_0.set_rx_agc(True, 0)
RuntimeError: RuntimeError: NotImplementedError: set_rx_agc() is not supported on this radio!
Is there an AGC loop on the TwinRX?
