I believe it's TRX-B and RX2-B , the LED lights should light up when the
ports are active.
You would directly modify the xml. change gain_mod manual, and add gain_dB
to rx site, and then modify tx gain to -65. Something like this:
```
{rx true,
tuning_freq_MHz 2450,
bandwidth_3dB_MHz 0.24,
sampling_rate_Msps 0.25,
samples_are_complex true, gain_mode
manual, gain_dB 0,
tolerance_tuning_freq_MHz 0.01,
tolerance_sampling_rate_Msps 0.01,
tolerance_gain_dB 1}, {rx false,
tuning_freq_MHz 2450,
bandwidth_3dB_MHz 0.24,
sampling_rate_Msps 0.25,
samples_are_complex true, gain_mode
manual,gain_dB -65,
tolerance_bandwidth_3dB_MHz 0,
tolerance_tuning_freq_MHz 0.01,
tolerance_sampling_rate_Msps 0.01, tolerance_gain_dB 1}
```
