Hi there! I’ve had an ADSB feeder online for around a year and I’ve never quite figured out what to do with the gain. I have this antenna: Radarbox Antenna (I know it’s not the best) and my goal is to figure out what gain would be the best for the furthest range possible. If anyone could help me find that out I’d really appreciate it.

I loaded this the other day and it improved my numbers and range.

Yeah, I’ve seen that one. I’m trying it right now so I’ll wait and see! Thanks for the recommendation.

Thank you for the response. How would I install the program with putty?

You just need to follow the steps under prerequisits
sudo apt install python3
sudo apt install python3-pip
sudo pip3 install beautifultable
You then istall the script
sudo wget https://github.com/sxb1n9/ADSB/raw/main/GAIN_CHECK/gain_check_v3.py
And run it
sudo python3 gain_check_v3.py

For some reason, it gives me that error when trying to run it. The script installed fine.

What image is on your SD card? It needs to be one of piaware, flightaware, adsb x or radar box. Any others, I don’t think it’ll work

Not sure then. I use piaware and it’s fine. Will need to wait for @b1n9

You need to adjust the following in the script to work with your setup
# PIAWARE SD SETTINGS (comment out and uncomment other settings to switch)
host = 'localhost'
port = 30003
config_file = '/boot/piaware-config.txt'
config_setting = 'rtlsdr-gain'
config_setting_after = ''
service_restart_cmd = 'sudo systemctl restart dump1090-fa'
# DUMP1090-FA on RASPBIAN
# host = 'localhost'
# port = 30003
# config_file = '/etc/default/dump1090-fa'
# config_setting = 'RECEIVER_OPTIONS="--device-index 0 --ppm 0 --gain'
# config_setting_after = '--net-bo-port 30005 --net-sbs-port 30003'
# service_restart_cmd = 'sudo systemctl restart dump1090-fa'
# DUMP1090-MUTABILITY on RASPBIAN
# host = 'localhost'
# port = 30003
# config_file = '/etc/default/dump1090-mutability'
# config_setting = 'GAIN='
# config_setting_after = ''
# service_restart_cmd = 'sudo systemctl restart dump1090-mutability'
My guess is that you need to use the second set but I don’t know how you adjust your gain currently you basically need to make those settings so they can adjust the config and restart the service that you use.
# ----------------------------------------------------------------------------------------------------------------------
# REQUIRED DUMP1090 SETTINGS DESCRIPTIONS
# host url of dump1090 (default PIAWARE SD)
# port 30003 = SBS port (default PIAWARE SD)
# config_file path and filename of where gain settings are stored (default PIAWARE SD)
# config_setting gain setting before the gain number
# (ex. "rtlsdr-gain 49.6" the config_setting is "rtlsdr-gain" no space after)
# config_setting_after gain setting after the gain number
# (ex. "rtlsdr-gain 49.6 something" the config_setting_after is "something" no space before)
# (ex. "rtlsdr-gain 49.6" the config_setting_after is "")
# service_restart_cmd command to restart service to apply changed gain (default PIAWARE SD)
