TCI Panadapter Spots

For Thetis (ANAN/Hermes-Lite 2), ExpertSDR3 (SunSDR), and other TCI-compatible SDR software: enable Push to Thetis/TCI panadapter in Settings → Display.

POTACAT connects via WebSocket and sends color-coded spot markers to your panadapter with black text labels for readability. Configure:

  • Host and port (default 127.0.0.1:50001)
  • Per-source filters (POTA, SOTA, DX Cluster, RBN, WWFF, LLOTA, FreeDV)
  • Max spot age

Spot Colors

Each spot source has a distinct background color on the panadapter:

  • POTA — Green
  • SOTA — Orange
  • DX Cluster — Purple
  • RBN — Light blue
  • PSKReporter — Red
  • Nets — Yellow

Text labels are rendered in black for contrast. POTACAT uses the Thetis JSON tag extension for text color compatibility.
