APRS DX Aggregator (V 1.6.5)

Using APRS for VHF propagation monitoring

APRS DX Aggregator is a program that allows APRS receiving stations to automatically upload APRS DX reports to DXMAPS so that they can be shown on the APRS DX maps, listings, etc.

The program takes the packets from the APRS server provided by your receiving software (like UI-VIEW32, for instance), interpret and filter them, and upload the data to DXMAPS server. Please notice that the program is not intended to connect to the APRS Internet servers, but to your own receiving software. Any packet forwarded via Internet will be ignored by APRS DX Aggregator.

Using APRS DX Aggregator is extremely easy and if you already have an APRS receiving station you can be uploading AIS DX reports in minutes. Simply follow these steps:

1.- Download the program, unZIP it and place it in any folder of your computer you whish (for instance C:\Program files\AprsDXAggregator). The program does not require installation in most of the cases, just place it in a folder and run it. If you get an error message indicating that some files are missing then download a full setup package , place it in an empty folder and run it from there (do no run it directly from internet)

2.- Enter your amateur radio callsign, your locator/grid square, the frequency your are receiving.

3.- Choose how the APRS DX Aggregator must behave:

Simulating an APRS server: Enter the port where it must listen and then press "Start monitoring". This option is specially interesting fro devices (like the Microsat) and software that allow data sharing with APRS-IS servers.
As a client: Enter the IP address and port where your receiving software is sharing the packets. Then press "Start monitoring". This option is mainly for UIVIEW32 and other programs sharing data as servers.

Example of configuration simulating an APRS server, for instance for connecting to Microsat devices.

In this example APRS DX Aggregator listens on port 1448, but you could configure any other TCP port not in use.

When "Start monitoring" is pressed the program will wait for a connection. Once Microsat (or another software) connects to APRS DX Aggregator, If all is OK you will see the APRS packets received in the "Raw message received" box. Otherwise it means that either the IP address or port are configured in Microsat or other receiving software and don't match with APRS DX Aggregator.

Leave the program running (you can minimize it if you want). As soon as it detects a coherent reception of a station above 400 km it will automatically send the information to DXMAPS.

Example of configuration as a client, for instance to connect it to UIVIEW32.

Please notice that if APRS DX Aggregator is running in the same PC than the receiving software you can use the localhost (127.0.0.1) IP address. If it is running on a different PC then you must use the IP address of that PC.

Optionally you can also also specify a connection string to sent when connecting to the server, if it requires it. It should be left blank in most of the cases.

If all is OK you will see the APRS packets received in the "Raw message received" box. Otherwise it means that either the IP address or port are configured in APRS DX Aggregator and in your receiving software don't match. Please notice that port 1448 used in this example is the default port of UI-VIEW32, but it can be a different port in your system. Just make sure that it is the same that you have configured in your receiving software for sharing the data.

Leave the program running (you can minimize it if you want). As soon as it detects a coherent reception of a station above 400 km it will automatically send the information to DXMAPS.

If you are using UI-VIEw32 for receiving APRS, go to "Setup - APRS server setup" to enable the local server, as show below.

Please notice that UI-View32 server by default uses port 1448, but that this value could be changed in the PORT entry in the [SERVER] section of UIVIEW.INI file.
