WsjtxUtils.WsjtxMessages

The WsjtxMessages library contains the classes and methods needed to serialize and deserialize WSJT-X messages in the QT QDataStream format specified in the WSJT-X source code in NetworkMessage.hpp.

We can easily read messages from a memory source using the extension methods provided.

Memory<byte> source= new(new byte[] { 0xAD, 0xBC, 0xCB, 0xDA, 0x00, 0x00, ... };
WsjtxMessage? message = source.DeserializeWsjtxMessage();

We can write messages to a memory source just as quickly.

Clear message = new("WSJT-X", ClearWindow.BandActivity);

var buffer = GC.AllocateArray<byte>(1500, false);
var numberOfBytesWritten = message.WriteMessageTo(buffer);

WsjtxQsoParser is a utility class attempting to extract as much relevant QSO information from 77-bit modes (FST4, FT4, FT8, MSK144, Q65) WSJT-X Decode messages. The returned WsjtxQso will have the state of the QSO in progress and callsigns, grid square, and report if available.

var qso = WsjtxQsoParser.ParseDecode(decode);
 
var dxCallsign = qso.DXCallsign;
var deCallsign = qso.DECallsign;
var grid = qso.GridSquare;
var report = qso.Report;

WsjtxMessages does not contain a server implementation to allow flexibility and use cases where no server or a custom server is required. A basic UDP server using WsjtxUtils.WsjtxMessages is available with WsjtxUtils.WsjtxUdpServer.
