ON9CJX Is there a good example how to use broadcast. The manual is Chinees to me. We like to go over the internet from M1KE to M1KE.
FredFeddersen You will need to install a server on a Raspberry Pi or Ubuntu. I used a Raspberry Pi 4 I made one, and my 3 son's can call me anytime. I have a dashboard using local ip address and shows everyone connected. These instructions seem to be accurate if you've installed Raspbian on your Raspberry Pi: https://www.johndball.com/compiling-sharkrf-connector-server-on-ubuntu-16-04-lts/ It's for Ubuntu but the same should work on a Raspberry Pi. 73 SharkRF IP Server
HA2NON You don't need to install a server. Enable Sitelink server on one of the M1KEs and others can connect to it through the internet if they have Sitelink client configured and enabled. There's a diagram with example descriptions at the bottom of the user manual page https://manuals.sharkrf.com/m1ke/web/connectors/bcast.html
