Its my quick setup to use a rpi as a sdr server.

The deploy playbook will configure a fresh raspios instalation to serve as a sdr server.

• Raspberry Pi OS Lite 64bit - debian 11 bullseye
• Raspberry Pi 3 B+ hardware
• RTL2832 usb hardware

• Build a raspberry pi os sdcard.
• You can easily build a sdcard using rpi-imager tool.
• Connect rpi wifi/ethernet to internet.
• Have ssh access to rpi with sudo powers.
• You will need to have ansible installed (in your pc, not in rpi host):
• Ansible Instalation Docs.
• Clone this repository:
• git clone https://github.com/braghetto/rpi-sdr-server.git
• Change to repo directory:
• cd rpi-sdr-server
• Run ansible deploy playbook inside repo directory:
• ansible-playbook deploy.yml
• You be prompted for rpi ip address, ssh port, ssh username, ssh password, telegram bot token, bot owner id and bot group id.
• Grab a beer and wait, we'll be compiling a lot of stuff using rpi hardware...
• Wait for rpi reboot.

• spyserver
• soapyremote server
• telegram bot
• rtl_airband
• rtl_tcp
• calibration tool
• rtl_433 tool

• spyserver.service
• soapyserver.service
• telegrambot.service
• rtlairband.service
• rtltcp.service
• rtl433.service

• spyserver /etc/spyserver.config
• rtl_433 /etc/rtl_433.conf
• rtl_airband /etc/rtl_airband.conf
• telegram bot /usr/local/src/telegrambot/bot.py

• Its possible to change telegram bot TOKEN, GROUP_ID and OWNER_ID inside file: /usr/local/src/telegrambot/tokens.py
• If you want to change the airband channels you can change their names in: /usr/local/src/telegrambot/airband.py
• The telegrambot service is enabled by default.
• Do not run or enable multiple sdr services at same time.
• Use systemctl to start/stop or enable/disable sdr services.
• Use calibrate command to ajust ppm error.
• Calibrate script is very tailored for my use case and my dongles, you probaly want to change it.
• Channels configured by default in the airband are specific to my region, you probably want to change them too.
• Use only one usb RTL2832 dongle at time.
