UHDDevice.cpp:611:setRxGain: Requested non-existent
channel 1
The error comes up because in MCBTS there is only one physical channel
- as in one hardware RF gain element. So the receive gain on channel 0
is effectively a global setting for all ARFCN channels; gain on each
ARFCN cannot be set independently.
Note that the transmit side behaves differently. The same gain effect
exists for all channels, but there is no warning. Instead, the gain
control command is sent to the device regardless of which ARFCN is
selected.
Perhaps we should make the Tx and Rx gain behavior consistent. I'm
open to suggestions.
