This script will automatically control a rotor (both azimuth and elevation) based on data obtained from APRS packets (locally via TNC, or APRS-IS).
- Download the script
- Install these dependencies:
- hamlib2 (
sudo apt-get install libhamlib2 libhamlib-utils) - Math::Round (
cpan install Math::Round) - Ham::APRS::FAP (
cpan install Ham::APRS::FAP) - Screen (
sudo apt-get install screen)
- Change the variables in the top of the script
- APRS-IS users will need to enter their callsign and password. The password is a hash of the callsign; google it.
Run rotctl -l to list all of the available rotors. At K5UTD, we are running a Kenpro G-5400, and the homebrew interface board uses the Yaesu GS-232B protocol, so our model number is 603.
I recommend running both of these commands in screen sessions so you can disconnect and come back later, but two terminals will also get the job done.
rotctld -m 603 -r /dev/ttyACM0
