Weather station transmission
When you transmit as a weather station, you should
set the weather station’s settings, and input the
weather data to the [DATA] terminal.
You can input the weather data from a third party’s
weather device by converting it to the APRS weather
format in your PC or microcomputer.
After completing the weather station’s settings, and
inputting the weather data, you can transmit as a
weather station.

Depending on the PC environment, the COM port number
used by the ID-4100A/E may be higher than 5. In that
case, use an application that can set it to higher than 5.

Confirming the weather data input
You can confirm whether or not the weather data is
input to the [DATA] terminal.
1. Set the “GPS TX Mode” to “D-PRS,” and the “TX
format” to “Weather.” (pp. 5-21, 5-22)
2. On the standby screen, push [QUICK].
3. Rotate [DIAL] to select “Weather Information,”
then push [

].
• Displays the weather information screen as shown
below if the weather data is input to the [DATA]
terminal.

When the weather information is displayed, you can
transmit as a weather station. If “-” is displayed on
the screen, the weather data does not input to the
[DATA] terminal. In that case, check the input data
settings.
