Select your audio device for transmitting. It must be using a sample rate of 48000Hz

Rig Control

This section is where you configure rig control method (none (VOX) or hamlib) for both GUI and TNC. For the best experience hamlib control is recommended.

None/Vox

Select "None/Vox" if you want to use Vox for triggering PTT. No connection to rigctld will be established. No frequency information is availble.

Hamlib

Select "Hamlib" if you want to have more control over your radio. Define your hamlib settings in settings, and click the start button to start rigctld. You may use the 'PTT test' button to ensure rig control is working.

SSID

Enter your callsign and SSID. Your callsign can have a maximum length of 7 characters

Enter your position as a 4 or 6 digit grid square, also known as a maidenhead locator. Six digits are recommended.

Auto-Updater

The auto updater loads the latest version from Github and installs it automatically. You can select the update channel in settings. Once an update has been downlaoded, you need to confirm the auto-installation and restart.

Alpha

Alpha releases are more frequent and contain the latest features, but are likely to be unstable and introduce bugs.

Beta

Beta releases are more stable than Alpha releases. They are a good tradeoff between latest features and stability. They will be updated less often. A beta release has not been released yet.

Stable

Stable releases are the most stable versions with no known major issues. A stable release has not been released yet.

Local tnc Remote tnc

Local / Remote switch. If the TNC is running on the same computer as the GUI, select local. Otherwise choose remote and enter the IP/Port of where the TNC is running.

tnc ip :

Remote IP of TNC. Port is port of daemon. The tnc port will automatically adjusted. ( daemon port - 1 )

Start tnc Stop tnc

Start or stop the TNC service. The TNC daemon must be running and will work whether the TNC is local or remote.

-38 dBFS (Audio Level)

Represents the level of audio from transceiver. Excessively high levels will affect decoding performance negatively.

-24 S-Meter (dBm)

Represents noise level of the channel from the transceiver. Requires hamlib rig control.

Tune

Adjust volume level of outgoing audio to transceiver. For best results lower the level so that a minimum amount of ALC is used. Can be used in combination with rig's mic/input gain for furthrer refinement.

Record audio

Create a recording of current channel

Send a ping to a remote station by entering a callsign and optional SSID (-0 will be used if not specified.) Alternatively click on a station in the heard station list to populate the call sign field. If the remote station decodes the ping it will transmit a reply. If able to decode the reply, a signal report will be listed in the heard station list.

Sending out a CQ CQ CQ to the world.

Sends a periodic broadcast (duration is definable in settings) that announces you are available. Check explorer to see other active stations that may have decoded your beacon.

Waterfall

Displays a waterfall for activity of current channel.

Busy Indicator busy

Green when channel is open and changes to red to indicate there is activity on the channel.

Signal Indicator signal

Changes to green when Codec2 data is detected on channel.

Constellation Plot

Displays a plot of last decoded message. A constellation plot is a simple way to represent signal quality.

Speed Chart

Shows history of SNR and bit rate of messages.

Stations that you've been able to decode will be listed here. Details such as time, frequency, message type, call sign, location and SNR will be listed. Existing entries are updated if they already exist and more detailed history can be viewed in chat window for each station.
