Editing Getting Started (section)

== First transmission ==
The default configuration is chosen to work immediately:

* Frequency '''4625 kHz''', power '''100 W''', modulation preselected with a '''2700 Hz''' bandwidth.
* Antenna: '''End-fed half-wave (EFHW) with 49:1 transformer''', 32.5 m wire at 10 m height. This antenna is close to resonance at 4625 kHz, which is why that frequency is the default. Changing the frequency far from resonance without changing the antenna produces a severe mismatch and very little radiated signal.

Steps:

# Set a callsign in the '''Station''' section (default PA3NL) and click the world map to place the station, or type latitude and longitude directly.
# In '''Transmission Source''', keep the source type '''Audio File''' and press '''Choose...''' to select a file, or drag an audio file onto the window. Supported formats: wav, mp3, aiff, aif, au.
# Press '''Start TX'''.
# Watch the '''Radio Deck''' on the right. Before the server reports data it shows a local estimate; once telemetry arrives the header changes to measured output. The session also appears in the '''Active Sessions''' list.

If the server is full the session is queued and the list shows the queue position, see [[Sessions and Queueing]].
