In this step we set the serial numbers of our RTL-SDR device(s). You can skip this step if you're not using an RTL-SDR radio (for example: bladeRF).
As most RTL-SDRs ship with the same serial number, confusion may be caused if more than one SDR is present. It is a good rule of thumb to change your SDR serial numbers to match the frequencies they receive for.
The remainder of this guide assumes that:
The SDR used for ADS-B Mode-S (1090MHz) reception will have a serial number of 1090
The SDR used for ADS-B UAT (978MHz) reception (if used) will have a serial number of 978.
To set these serial numbers:
Unplug all SDRs, leaving only the SDR to be used for 1090MHz reception plugged in. Issue the following command:
You should be presented with the following. Your details may differ slightly, however ensure the device's new serial number will be 1090. Press y to proceed.

Next, if you intend on receiving ADS-B UAT (978MHz) data with a second SDR, Unplug all SDRs, leaving only the SDR to be used for 978MHz reception plugged in. Issue the following command:
You should be presented with the following. Your details may differ slightly, however ensure the device's new serial number will be 978. Press y to proceed.

Unplug all SDRs and then plug them back in again to make the system aware of the new serials. A reboot will not accomplish this. If you have more SDRs, repeat the above process with each of them, replacing the last number in the command with your desired serial number.
