Re: Simple programs to run
Thank you Ron, Understand what you are saying.? I guess I best sit down and figure out what I¡¯m trying to accomplish with this. Honestly, I haven¡¯t really thought about it. Like Kyle, I¡¯m primarily a contester with POTA chasing when no contests are going.? Currently chasing grids on 6m.? So I¡¯m thinking my focus is going to be on improving my ability to accomplish these goals. Let me think about this some. Here is the current local rundown. My station is a Kenwood TS 890 for hf work with an Ic7100 used primarily for vhf/uhf. The towers/beams are gone sine I cannot maintain them ( no climbing decree), so that eliminates rotor control etc. ?zero five 40-10 ground plane and inverted v¡¯s comprise the antenna farm. The amp is also gone as it didn¡¯t get used, however that is not to say another May show up. Thanks again, let me crawl back into my man cave and contemplate exactly what I want to do with this. 73

It might be useful if you provide some insight into the types of devices you're planning on integrating into Node Red. Then with the group's help, we can point you at hopefully existing flows for you to try. Then you can use that as a stepping stone to move forward.
73, Ron WB2WGH Good morning,
I¡¯ve reached the point of wanting to built simple programs to learn how the different nodes interact.? I found a couple on the node red web site but one doesn¡¯t do anything while the other is a little too advanced for me at this stage.
The ¡°dummies ¡° (remember them lol) books used to be great with simple building block type programs for us dummies. An in depth search indicates no dummies books for node red. Perhaps indicative that there are no ¡°dummies¡± in the node red world . Lol ?
Bottom line, is there any place where I can find some sample type programs that I can use in my learning process?
Watching Kyles videos have been extremely helpful, after watching 2 to 3 times, I¡¯m even beginning to understand him.? At 81, this is a major accomplishment. Thanks Kyle.
Last but not least, thanks to the group for the welcome and the resolution of my first problem concerning the dashboard.
Hopefully, the problems encountered will be mininual.
Y¡¯all have a good day and week.

Adrian, not easily done as there are a number of unrelated changes. It should be easy to populate the table with your power settings. Let me get you the flow when in the shack tomorrow. Ron WB2WGH?
Ron, Are you able to export the added sections you can email me, so I can just import those into my existing respective flows please ?
Mainly because of my custom SPE power scales and type etc.
Thankyou
Adrian

Adrian, thanks for the video. I'll get you the SPE beta version tomorrow. Provides similar functionality to your tweak, table driven (you customize the table), 4 drive level columns (standby, L, M, H) and a row per band. A link out node to couple with a corresponding exciter flow's link in. Ron WB2WGH?
Ron, A little vid of my basic setup ;

Alan,
Sorry I don¡¯t have a computer with me at the moment (traveling) so this is from memory. there¡¯s a pan.data = function(data) that I think does that part.?Likely Wednesday before I can actually look at the code.

Stephen, thanks.
Another question.? I have built my first d3 SVG line chart.? I am looking over your "Panadapter" Dashboard template node and cannot identify where you bring in the msg.payload as "data" from the Flex Steam node.
I am looking for something?like ".data(msg. payload)", but I do not see anything similar.
Q- How/where, do you bring the msg.payload array from the Flex Stream Node into the d3 script?
Alan
Alan,
Should work. You just need fix the y-axis to the audio data range and?then use the Left or Right channel data for display. Or merge them into mono channel¡. or display both!
The only trick will be creating a rolling buffer of data with new values pushed in from the left or right (visual left or right not audio channel) so that new data appears on the left or right of the display. So you get:
? ? newest sample ¡¡ oldest sample
or
? ? oldest sample ¡.. newest sample
I don¡¯t think you are missing anything. In fact I recall looking at examples just like this when building the original. I don¡¯t recall if they were for audio data, but they were for data where new samples were added and then ¡°scrolled¡± across and expired off the other end of the chart.

Adrian, I have already coded an option for exciter drive level "output" parameter based on band and SPE power level setting. The user configures the table in Node Red much like the SOE does it for Flex. I have not released that version yet for beta rest but can and will get you a beta in the next few days.?
The challenge has been to ensure the lookup is performed on "valid" SPE data. Without blgetting into the details, sometimes the CSV data is corrupt (bad checksum or wrap around of the data). That has resulted in adding additional code to verify packet validity as I don't want to perform a drive level lookup based on bad data.?
I'll get you a beta shortly. Ron WB2WGH?
I see using
msg.payload.col10? in debug
"H"
27/06/2022, 17:03:54msg.payload.col10 : string[1]
"M"
27/06/2022, 17:03:54msg.payload.col10 : string[1]
"M"
27/06/2022, 17:03:55msg.payload.col10 : string[1]
"M"
27/06/2022, 17:03:55msg.payload.col10 : string[1]
"M"
27/06/2022, 17:03:57msg.payload.col10 : string[1]
"L"
27/06/2022, 17:03:57msg.payload.col10 : string[1]
"L"
27/06/2022, 17:03:57msg.payload.col10 : string[1]
"L"
which should be simple to tap.

Re: Question about how to "zero" meter data when radio connection is dropped
Dave,
Much thanks for your flow, it was VERY helpful... though I do have a question about your flow.? After the switch node, you have a split node then a delay node.? Curious as to the purpose/function of the split node since you know the radio is "disconnected" from the switch node.

Re: Dashboard Alignment Issues
Dave, Alan:
Finally figured this out. Dave, you were right. It was a layout issue.
Once I changed the group width of the WebSwitches from 3 to 4 (in the Dashboard group nodes) and the switch sizes to Auto (in the switch node Properties) then the dashboard started looking just like the pictures you had posted. Now I can use spaces in the labels and everything looks like it should.

Re: Question about re-install
Click the three horizontal lines in upper right corner of Node Red Editor and select export. You can select current flow or all flows.
Make sure you install all needed nodes on new Node Red install before importing flows back in.
What is the problem you have?

Stephen - Question
I was poking around with your pan adapter and D.3 based frequency domain chart. ?I am learning a lot.
Question, I tried resetting the Steam type to the different audio modes. ?The message output appeared to be the same as the panadapter's output.
My thought was to build a d3 based, frequency domain chart of the audio spectrum. ?What am I missing?
