2.3.0

https://modem73.app

Changelog

  • New Ranked CSMA: Turn order derived from 2-FSK station presence tones and beacon, 3-7x faster turnaround on nets where every station can hear every other one. Useful for simplex VHF/UHF, HF NVIS nets, and repeaters.
  • CSMA settings reorganized into THRESHOLD / SYNC / RANKED modes
  • Shareable copy & paste config token under Config for easy setups
  • Fast Floor option for shorter Sync waits
  • Population adaptive contention windows in Sync CSMA mode, sized from how many stations have been heard recently based on the lead tone
  • RIG frequency presets when rigctl PTT is enabled
  • TX delay is now configurable from the Config tab
  • TUI fixes

All stations must be on 2.3.0 to make use of these new features

See the README for building from source
