Following on from my initial article on plotting realtime WSJT-X decodes on a Node Red map I’ve made a few enhancements to the flow so that it includes even more data then before.
The additions to the flow now enables collection of status information from WSJT-X so that the flow is able to capture the frequency that the radio is tuned to and also the mode that WSJT-X set to. Neither of these two bits of data are in the decode message payload and so a separate mini-flow has to be created to collect the data from the status payload along side the other main flow.
Since the status information needs to be available to all other flows I used flow variables to store the status information in so that it can be addressed directly from any of the other flows in the Node Red app.
If you’d like to use the flow in your radio room then I have put a download link below for a file that you can import into Node Red and build the flow in an instant.
More soon …
