Good to hear you have it working.
Other image sizes are possible by changing some of the function code.

Alan, you mean put spacers between the W2 WATT METER and the Flex Radio group so it forces the Flex Meters group to the 2nd row, but then doesn't overlap the lower left hand corner of the Flex Radio group hanging down?

I'll see if you can complete your button idea...my only issue with that is, anybody who connects with a larger resolution, there is going to be this spacer hanging out on the dashboard, right?

Just wish NR did a better job of dynamically arranging the UI based on screen resolution.

I live around 3 hours from a three tower M/2 contest station and have the opportunity to move my Flex down to the station full time as one of the two operating positions. The contest station just got 500Mbs fiber up/down so remote capabilities are now possible.? I'm hopeful we will get another Flex for the 2nd position in the near future.? Now I just need to purchase another Flex for my original remote station!? Lot's of Flex's in my near future.? LOL.??

As of right now, there are three hurdles that we must overcome to gain full access to the station without the amps.

Here is the setup.

One SixPack antenna switcher 2x6 with a rotary knob controller.? This controls tower what position is on what tower.? Tower 1 (6m yagi, 80M vertical, end fed), Tower 2 (40 meter beam), T3 (80M dipole, 20/15/10 Tribander, 160m diploe)



Each tower has an Ameritron RCS-4 antenna switch at the base to switch the antenna on said tower.? Rotary control box in the shack.

?

Rotators are Hy-Gain.??



Power meters are LP-100A but after the 800W amp which we are not using.



**

Here are my questions regarding how to control all this via Node-Red.

The LP100A is solved, as I believe there is a flow for that and it has serial on the back of the box.??

On the Six Pack antenna switcher, how do I switch that remotely?? Is that with the BandMaster box by Array Solutions?? Is there another solution?

Same question regarding the Ameritron antenna switcher.? I don't think it has serial out or I haven't seen a flow for that if I can get serial out of it.

The Hy-Gain rotators have an RS-232 kit board from Ham Supply I can purchase that brings RS-232 out the back and I'm assuming I can use another rotator node-red flow for a building block for building a new flow for the Hy-Gain.

I know this forum isn't station design, but thought some of you might have an idea on what to purchase so I can eventually control all these things with NodeRed in the future.

Thanks

As a new user in the last 3 or so months and virtually no programming experience, here are some things that confused me the first time around after the install.? At first I think you very briefly go over the install of NodeRed.? The instructions on the Wiki are very good.

I don't think you get into FRStack at this time as that's a very confusing flow to load as one of the first.

What is controllable and what are the limitations of NodeRed?
What do you NOT want to control or monitor via NodeRed?

General Items
1) Loading your first flow
2) The panel layout on the right hand side and what the different tabs are
3) Installing required or useful pallets
4) How to make a backup
5) How to get to the UI after deploying your first flow
6) How to tweak the UI
?- tabs vs groups
7) How to debug and troubleshoot your flow
?- expanding debug output default

Nodes
1) What are the basic and popular nodes and their functionality (inject, switch, change, etc..) we would use in ham radio?
2) msg.payload and some background on how the nodes pass information from node to node
3) How to pass more than one payload from node to node
4) Again, more debugging and troubleshooting flows.??
5) How to disable nodes to remove them from the flow and how to disable whole tabs.

Formats
1) JSON and array data
2) Strings
3) HEX
4) How to convert data from one type to another

Connecting to devices
1) TCP
2) Serial

Dashboard
1) Overview of some of the different dashboard graphics (gauge, meters, LED, etc)
2) How to get to the dashboard
3) Column widths and how some dashboard nodes are locked vs unlocked and how to change them

How to get started with your first "from scratch node"
1) Are there basic things you should be thinking about?
2) What type of data is coming out of the device that you need to read?
3) How to inject commands back into the device via an action?
4) Are there other troubleshooting tools other than the debug node?

Good net resources to help you get unstuck on a problem?

I could probably go on and on, but I'm sure most of these topics could spawn other questions.? Problem is going down the rabbit hole once a question is asked.

For the azimuth map, once I have created it in PDF format I import it to Microsoft Word. I convert to Word document then I can delete the header info leaving just the map. I right click the map and save as PNG. Next edit the PNG file in MS Paint and resize to 500 x 500 pixels.

I decided to leave the header as a reference at hand. Another way to eliminate the header is to create the map on pdf and use snipping tool to select the desired area (no headers) and save the snip as PNG, then edit in MS Paint for resizing.

Gary, followed same principle but created a different map to sort of have a different perspective. It is a bit off center but close enough for the purposes of having an idea.

So I've downloaded this node and it displays, but I get an ECONNECREFUSED error on the GetSPEINFO function.? What am I missing in the setup?? The IP address is set to the radio (192.168.1.34:4996).

My Node-red is running on a Pi, and it feels like I need a port setting opened up but I'm pretty sure I don't have firewall installed (yet)

Any ideas?

Thanks, just did it with same map to try. Will come up with a different map of interest tomorrow.

good night.

Yes, just duplicate the Svg node and use a different map. I ended up adding duplicate controls also and then put the US map on another page. I can then select if I want the World or just the US heading display.

Interesting. How do you do it? Duplicate the Svg node? Will try it tomorrow.

It's possible to zoom in and have a US (or anywhere) map also. Both maps can be functional at the same time if desired.

After a couple of swing and misses I got it. Created the file and found how to import it. I configured the zoom/pane features and the coordinates on mouse over. Great addition to dashboard.

Hi all

For members who are using Node Red for the first time, we are looking for simple comments on your initial experiences using Node Red.?

The purpose is to show new Node Red users how easy it is to get started. Getting Node Red loaded then installing some existing flows and then customizing to your needs.?

If you want to convert the image to a transparent background, I use this online editor.

Great addition! Thanks for sharing.

Here is my version showing the actual antenna pattern width.

Make sure it is 500 x 500 pixels. You can use Microsoft Paint to resize it. Then save as PNG file.?
