Interesting Uses of the UDP Broadcast Data - n4af/TR4W GitHub Wiki

This page describes uses of the UDP Broadcast Data now sent from TR4W in version 4.45. Note this emulates the same broadcasted data used in N1MM. If you are a developer and would like to use this data, please see this site. I also encourage you to set the SO_REUSEADDR socket option BEFORE you bind to your socket. This allows multiple programs to all listen to the broadcast data on the same PC.

I have been using ClubPi this evening and it is quite a nice system. This is a piece of software that runs on a Raspberry Pi and in real-time sends contact to ClubLog.

Another cool little utility is UDP Display by K6KAL. This makes use of the radio broadcast data to show the frequency on a much bigger window. It also shows the last QSO made. I'm thinking this would be a nice tool to run at our club station to have a monitor that shows the frequency info to engage folks a bit more. More info is here: http://www.qsl.net/k6kal/

I have spoken about the DXKeeper bridge to send contacts from TR4W to DXKeeper automatically.

As I have mentioned before, if anyone wants to implement a bridge to any other logging program (like HRD), then one only needs to have a UDP listener to receive data from TR4W (or N1MM-same interface) and then send the message to the program of your choice. If a Logging vendor wrote this, they could implement the listener right in their program.

This has the benefit of not slowing down the primary contest logging capability of our software with a TCP/IP connection and let's others write whatever interface they like.

I use DXKeeper so I have no need to write another interface to something like HRD, but if a user of HRD or something else wants to implement the bridge, it is not very difficult.

More links to programs I have found that use the UDP Broadcast data

  • Qsorder - Contest Audio Recorder
  • ClubPI - DXPedition/Contest aggregator to send contacts to ClubLog in real-time
  • PstRotator - Rotator Control Software
  • DXKeeper Bridge - Allows contacts to be sent to DXKeeper in real-time
  • UDP to COM Converter - Utility to convert UDP frequency information to Kenwood compatible COM commands to drive SDR and other devices.
  • N1MM_VIEW - Set of Python scripts to generate graphical charts and maps for Field Day (and other contests). Made to run on a Raspberry Pi (or anywhere else that can run Python). It also will create just PNG files for saving to a web server.
  • UDP Display - Windows program that displays frequency and last contact in as large a window as your system supports.
  • AA0Z NodeRed Contest Dashboard - NodeRed flow to show a map of last contacts as well as radio information and other statistics
