Station Preferences

• Callsign:
  1. If you have installed your QTH license, you will be able to select your callsign in the popup menu.
  2. If you are using QTH without a license, you will see NOCALL in the popup. QTH will be unable to transmit any outgoing information, but you will be able to receive and view data.

• SSID:

  This suffix, which is generally a number, will be appended to your callsign. This is useful for differentiating between different stations that may be using the same callsign, such as a home station and a mobile station.

  Here are the recommended SSID conventions:

  SSID	Recommendation
  -0	Your primary station usually fixed and message capable
  -1	generic additional station, digi, mobile, wx, etc
