ASTRS - A Simple TFAR Radio System is a Quality of Life mod for the ARMA 3 written by Chatter and M3ales which allows you to save/load your TFAR Radios configuration via an ACE Self Interaction.
The mod stores data locally in profileNamespace which means it stores configurations on a per profile basis. This has the added side effect of requiring you to save a new configuration for each profile you make use of, but also ensures you can have different LR configurations for different units etc.
