I’ve desinged a script what collect the activator-callsigns from pota.app spots and activations-scheduler-subpage.
My script run every 5 mins. to collect callsigns, deduplicate them, generate the file where the calls are comma separated in.

You can download the txt-file and import it in JTalert via Settings, Wanted callsigns. You can also import the calls in your wanted list at JTDX, JTalert or wherever you want. Feel free to improve it and build own import script.

You can point it to this permanent file-link: https://dm3ks.de/pota/activator_callsigns.txt

Let me know your suggestion for improvement.
