Science, Technology, Engineering & Mathematics


DMR talk group 31630 is where people can have a discussion about anything that results in learning about science, technology, engineering or mathematics and NOT make it 100% related to amateur radio topics.

STEM is easy to remember for such a BIG idea!
  • Casual discussions about STEM topics are encouraged to happen at any time from anywhere in the world with anyone.
  • Scheduled discussions however help make it easy for like minded people to listen in or join in active discussion.
