+# A rude work around to get JTAlert v.2, N1MM Logger+ 1.0.7422.0 (first version with WSJTX support), and WSJT-X 2.0 working
+# together.
+#
+# 0. Start this program (python 3.x)
+# 1. Start wsjt-x. Configure UDP server port to be 224.1.1.1, port 5007
+# 2. Start N1MM. No configuration possible for wsjtx window
+# 3. Verify that N1MM's wsjtx window is receiving CQ spots from wsjtx
+# 4. Edit the file C:\Users\<YOURUSERNAME>\AppData\Local\WSJT-X\WSJT-X.ini
+#     add these two lines above the UDPServer=224.1.1.1 line:
+#        udpserver=127.0.0.1
+#         udpserverport=2238
+#     Put a comment in front of the UDPServer= and UDPServerPort= lines, like this:
+#           #UDPServer=224.0.0.1
+#           #UDPServerPort=5007
+# 5. Save the file.
+# 6.   Start JT-Alert (JTAlert will read the .ini file with the 127.0.0.1:2238 values, and start receiving packets
+# 7. Comment out the 127.0.0.1:2238 UDPServer lines with #
+# 8. Save the file again.
+
+#  You'll have to do this again each time you start up JTAlert to 'fool' it into using port 2238.
+#
+# Issues: JTALERT-X closes it's socket connection while the settings dialog is open. We do the brute force thing of trying to
+# reestablish the connection to the port
+
+
+# WSJT-X talks to a multicast port. This program sits on the multicast port, and forwards packets it receives to other Unicast sockets.
+# It also listens on the unicast sockets, and forwards received packets back to WSJT-X.
+
+# It assumes that there's only ONE other application sending packets to the multicast socket (WSJT-X)
+#
