STEP-1: Add this repository to list of apt sources by following 3 commands:
First two commands are long. Please scroll right to see and copy them in FULL.

sudo wget -O /etc/apt/sources.list.d/abcd567a.list https://abcd567a.github.io/debian11/abcd567a.list

sudo wget -O /etc/apt/trusted.gpg.d/abcd567a-key.gpg https://abcd567a.github.io/debian11/KEY2.gpg

sudo apt update

STEP-2: Install packages
sudo apt install piaware
sudo apt install dump1090-fa
sudo apt install piaware-web
sudo reboot

For USA only - dump978-fa
sudo apt install dump978-fa
sudo piaware-config uat-receiver-type sdr

If you want to receive both ES1090 and UAT978, then two dongles are required, one for 1090 MHz and other for 978 MHz. In this case you will have to serialize dongles so that correct dongle+antenna sets are used by dump1090-fa and dump978-fa. Serialize dongles as follows

For 1090 Mhz dongle: use 8-digit serial # 00001090
For 978 Mhz dongle : use 8-digit serial # 00000978

(1) Issue following command to install serialization software:
sudo apt install rtl-sdr

(2) Unplug ALL DVB-T dongles from RPi

(3) Plugin only that DVB-T dongle which you want to use for dump1090-fa. All other dongles should be unplugged.

(4) Issue following command.
rtl_eeprom -s 00001090

Say yes when asked for confirmation to change serial number.

(5) Unplug 1090 dongle
(6) Plugin only that DVB-T dongle which you want to use for dump978-fa. All other dongles should be unplugged.
(7) Issue following command.
rtl_eeprom -s 00000978
Say yes when asked for confirmation to change serial number.

(8) Unplug 978 dongle
IMPORTANT: After completing above commands, unplug and then replug both dongles.

(9) Configure dump1090-fa and dump978-fa to use their respective dongles.
sudo sed -i 's/^RECEIVER_SERIAL=.*/RECEIVER_SERIAL=00001090/' /etc/default/dump1090-fa
sudo sed -i 's/driver=rtlsdr[^ ]* /driver=rtlsdr,serial=00000978 /' /etc/default/dump978-fa </br>

sudo reboot
