WFB Transmit is a drone-profile page at /transmit: WFB-tx adapter, channel, bandwidth, MCS index, and TX power. Home shows the same card.

​
Fields

The WFB Transmit card carries a state badge (active, ready, connecting, error or disabled) and these rows:

​
Empty state

When the state is disabled, or error with no interface, the card reads “WFB-tx is not running. Plug in an RTL8812EU dongle and set the channel + tx power in Settings”. The agent starts the transmit pipeline automatically when an adapter and a channel are both present.

​
Data source

GET /api/wfb, every 2 s.

​
Change channel and TX power

The dashboard’s Settings has no radio section. Change the channel and TX power from Mission Control, or through POST /api/wfb/channel and PUT /api/wfb/tx-power. Both are refused while the vehicle is armed (see Safety interlocks). See WFB-ng for channels, power limits and pairing.
