Information for programmers

The following information is provided for software authors who wish to exchange data with the new DX Summit web site. A basic understanding of the HTTP protocol is assumed.

Retrieving spot data

To receive DX spot data from the DX Summit system, use the URL http://www.dxsummit.fi/DxSpots.aspx with the parameters below. Once the HTML page has been retrieved, the spot data is located between the <pre> and </pre> tags and can be extracted and parsed.

Example:

The following URL will fetch the last 50 HF DX spots: http://www.dxsummit.fi/DxSpots.aspx?count=50&range=2
The following table provides all possible values for the range parameter and specifies what type of data is retrieved in response.

Retrieving custom spot data

To receive customized DX spot data from the DX Summit system, use the URL http://www.dxsummit.fi/CustomFilter.aspx with the required parameters below. Once the HTML page has been retrieved, the spot data is located between the <pre> and </pre> tags and can be extracted and parsed.

Example:

The following URL will fetch the last 50 20m DX spots: http://www.dxsummit.fi/CustomFilter.aspx?customCount=50&customRange=14

The following table provides all possible values for the customRange parameter and specifies what type of data is returned in response.

Retrieving announcement data

To receive announcement data from the DX Summit system, use the URL http://www.dxsummit.fi/Announcements.aspx with the required parameters below. Once the HTML page has been retrieved, the announcement data is located between the <pre> and </pre> tags and can be extracted and parsed.

Example:

The following URL will fetch the last 250 announcements: http://www.dxsummit.fi/Announcements.aspx?announcementCount=250

The following table provides all possible values for the announcementCount parameter and specifies what type of data is returned in response.

Example:

The following URL will send a spot from OH2BH who is spotting OJ0DX on 14025.5 with a comment of “very strong”: http://www.dxsummit.fi/SendSpot.aspx?callSign=OH2BH&dxCallSign=OJ0DX&frequency=14025.5&info=very strong
