 Hi The dash board has limited space , has anyone find a way to fill the whole dashboard? with scroll bar to the side . ?Instead having links can i have everything on page on ?? -- Nick W7NIK

Re: Initialize relays at RasPi startup
Domenick For my GPIO based relay flow, to "initialize" a relay on Node-Red restart, just change one of the "Test" inject nodes to inject one second after start. ?This will position the relay and store he result in context memory. ?I show below an example of using the "false" or open the relay, as an example. Of note, one of the issues with Raspberry Pi GPIO pins, is the first initial "state" on boot up is undetermined, that is the purpose of waiting one second to initialize the relay. ?Keep in mind, as a result, the relay position could be anything for the first second before the "initialize" inject node fires off.

Re: Initialize relays at RasPi startup
For automatic just use an object node to send Boolean false. Connect it to all the Pi relay GPIO outs. Set the inject to send once after 5 second then interval to never. When you start the Node Red server it will initialize the relays after 5 seconds.?

Re: Serial Control of the ERC-4 Rotator Controller
Hi Nick.? Yes I did add a map like Dave did.? I have uploaded my most recent versions of Rotator_20210806.json and Map_Interface_20210806.json to my wb0smx_Flows/ERC_AzMap directory (Note** Moved to !1! Flows by Type/ROTORS/ERC Controller/ERC_AzMap_wb0smx) in the files of this group.? The Rotator flow replaces the original ERC_Control flow that I posted earlier.? But you can change the name to whatever you like.
The two flows are designed to interface with each other through the link nodes.? I modified and simplified Dave's Map flow for my purposes.? It still shows the current beam heading and target heading (for 20 seconds after setting target), and allows for clicking on the map to set a target bearing.? The Rotator flow still has buttons for shortcuts to specified bearings, as well as free form input of bearings in text and numeric fields.
Good luck and enjoy...

wb0smx <rdpecken@...> added folder /wb0smx Flows/ERC_AzMap
The following files have been uploaded to
the Files area of the [email protected] group.

Description:
Flow to control Azimuth Rotators with Serial ERC-4 controller. Has links to the Map_Interface Flow, which will display an Azimuth map (with clickable steering).

Re: Scope Creep and Graphics: My Solution
Working on Mike's idea of a global MQTT broker to share data.
Is there any interest?
If so, what data is of interest? ?Seems like data similar to what is now "spotted" on DX servers would be a starting point. ?Since this data is now "public", sharing the same on a un-secured MQTT broker would be the same.
Anyway, I built a flow, to take the Frequency Data and MOX status from Daves's, WO2X, Flex API flow and upload that to the "test.mosquito.org" Public MQTT broker. ?To limit data flow, the TX frequency is only uploaded when MOX is on.
Here is a link describing the Public MQTT broker. ? ?
I set the topic to be "call_paramater", or in my case for frequency, ?"wa9wud_freq". ?I see others using Node-Red, wanting to know my frequncy, to subscribe to the same topic, and building flows to display.
Other ideas for designing the MQTT "topics" are welcome.
Depending on interest level, I will or will not pursue this idea.

Does anyone have a working flow to control and load frequency data to an Alpha 87a amplifier??

Re: Serial Control of the ERC-4 Rotator Controller
Randy?
thank you for the flow, did you add an Azimuthal map .
I was trying? to add a? map like? Dave did, but his flow required? PstrotatorAZ . any ideas ?
I works great ,?

Re: File /Node-Red DAX and CAT/nDAX nCAT Multi.json uploaded
#file-notice
Thanks, Mike.
For this project, I wanted to try running Linux WSJT-X.? I have repurposed?an i5 NUC to ?Linux Ubuntu, and am using that to run my Node-Red station, and now WSJT-X.
I want to compare Windows DAX, CAT, and WSJT-X to Linux nDAX, nCAT, and WSJT-X. ? So far the Linux device is very fast and stable. ?
I saw you were, too, setting up nDAX and nCAT.? How have you found it to compare to Windows?

Nice work,

I added a second Linux nDAX / nCAT Node-Red flow to add an optional second instance.
Here is the dashboard.? There are selectors for "Instance One" and Instance Two" to select Slice and DAX channel.? If "None" is selected for "Instance Two", only one instance of nDAX and nCAT is created.
It took some effort to create icons to run multiple instances of Linux WSJT-X, but I found a way.? Anyone who needs to know, email me.

Have you tried a different image writer?? I had the same problem and used a different image writer and all was fine.? You might also want to re-download another image just to make sure it's not already corrupt.?
