In this dialog you configure the hardware resources that EuroScope will use for voice input and output and the associated keyboard buttons. You also use it to calibrate the squelch and test the microphone sensitivity. After installing EuroScope you should come here at least once and perform the necessary settings and calibrations.
EuroScope uses two independent voice hardware connections, called the primary and secondary voice connection. The primary voice connection is used for your air frequency. That is the one, you select in the voice communication setup dialog with a check mark in the primary column. All other voice channels and also the controller-to-controller intercom calls are routed over the secondary connection.
It is possible to use the same hardware device for both, primary and secondary connections. But provided that your computer is equipped accordingly, you can also assign them to different hardware devices and have for example the primary frequency go to your headphones, while all secondary voice channels go to the desktop speakers.
To avoid confusion, all secondary voice output is automatically muted when the primary voice output is transmitting.
In the following dialog you can change and test your hardware:
- Primary and secondary input hardware – Use these combo boxes to select the primary and secondary audio devices to which the microphone is attached. They might be the same but can be different.
- Primary and secondary output hardware – Use these combo boxes to select the primary and secondary audio device to which your headphone or speakers are attached. They might be the same but can be different.
- Bass filter – If checked the built-in bass filter is enabled. Sometimes it sounds better and is easier to understand if only higher frequencies are transmitted and the bass is filtered out. But check it out yourself.
- Find squelch mode – When you press these buttons keep silence for about 5 seconds. During that time EuroScope analyzes the background noise of your system and adjusts the squelch level accordingly. You should test your system’s squelch value before using any voice connections.
- Test buttons – After pressing a (mike) Test button, speak normally for about 5 seconds. During this period EuroScope analyzes the volume level of your microphone input and displays the result as a message. Based on the result, you might want to change the settings of your audio device in your computer, for example enable the microphone boost check box.
- Set buttons – The Push To Talk buttons are used to transmit voice to the connected voice channels. It is not necessary, but highly recommended to define different PTT buttons for the primary and secondary voice connections.
