?Here's a happy new year treat. I was finally able to get a usable looking panadapter (or just the frequency part) up and running today. Using the "stream" node that I have been poking at on and off the past few weeks. The flow needed to create this is pretty simple with only one "function" node that watches incoming messages to see when a panadapter for the current client (need to be a GUI client to create panadapters) is created. Then the function node sets the X & Y size (1024, 512) and sends the stream id to the "flexradio-stream" node to configure it to listen for the stream/panadapter data. Lastly, that data is sent to a UI template node which is using D3js to make a chart.

The below example is at 10fps. I've not tried higher rates yet.?
This is also with NodeRed on a regular desktop computer (Linux) and displaying in a browser on a different desktop computer (macOS).

More details to follow ... next year after I get some documentation written up and clean up my example. Waterfall data to come next!
