# Agent dashboard: WFB Transmit

> The drone's WFB-ng transmit adapter, channel, bandwidth, MCS index and TX power on the browser dashboard.

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:

| Field | Shows |
| - | - |
| interface | the transmit adapter |
| channel | the channel number and its frequency in MHz |
| bandwidth | channel width in MHz, when reported |
| tx power | current TX power in dBm, and the adapter's maximum |
| MCS | the MCS index, when reported |
| domain | the regulatory domain, when reported |
| bitrate | transmit bitrate |
| packets | packet counter, once non-zero |
| restarts | pipeline restarts, once non-zero |

## 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](/drone-agent/dashboard-overview#safety-interlocks)). See [WFB-ng](/drone-agent/wfb-ng) for channels, power limits and pairing.
