TalkGroup 24098 is the Data-Voice-Meeting-Point of the Robust Packet Network community.
Here RPR, HF-RPR-APRS and PACTOR experiments on HF are coordinated.
Technical discussion and the daily small talk happen as well on TG24098.
The website http://robust-packet.st tells details of the groups activity.
The basic idea:
Spot stations on the HF-APRS map and talk to them instantly via BM DMR.
