Per-Station Tag Deployment

Toggle which tags each station should listen for. Selection drives the station's SDR tuning and matched-filter templates. Changes are staged locally — click Deploy to queue a set_tag_config command to the Pi.

Type DEPLOY to unlock. Queues a set_tag_config command that the Pi applies atomically on its next command poll (or immediately on LAN).

Distance Model Parameters

VHF tag signal propagation model based on path loss formula.

Typical VHF collar: 5-15 dBm
RTL-SDR stock antenna: ~2 dBi
Free space: 2.0 | Forest: 3.5-4.0
