Re: K4D and Node Red

 
Edited

Some thoughts off the top of my head:

1) Toggle between CW IIR and standard filters - with a complimentary adjustment of the pitch to be a multiple of 50

2) Sliders for AGC attack, decay fast/slow, slope, and threshold
3) Radio buttons for fan speed
4) Internal screen cap button? trigger the event
5) External screen cap button to trigger the event
6) Toggle of spectrum amplitude unit dBM/S-Units
7) VFO counts per turn radio buttons

8) TX and RX EQ sliders for each range

?

my apologies for the slooooooooooooow response.??? Not been on the interwebz much lately.

Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

Yep, glad you got it working.

I'm working on a dedicated WFD and FD dashboard that will be a separate screen, but nothing more to install, just an upgrade to the existing dashboard.?

Kyle


Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

Kyle, I got it working after a clean install.? Thanks for your help.


Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

Hey, that's ok.? Thanks much for your help, your videos, and this project.? I'm looking forward to using it at our club (W9ATG) winter field day.? I think at this point I'll just start over and bake a new pi (hi hi).? I probably screwed something up the first time.? 73's jon


Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

Jon,

You're above my troubleshooting level now.? Maybe someone else can chime in here as I think you've got some deeper issues of just trying to load the dashboard as it's not installing or recognizing some of your pallet nodes.? There is also a Node Red forum on the Node Red website that you can probably muster up some help, as there are back end developers that monitor that forum.

Thanks

Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

After the uninstall, I rebooted it.? Then in user settings, searched for node-red-node-sqlite and it says it is still installed.? So, I can't install it via the GUI.


Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

Thanks for your help, Kyle.?? Can I ignore these warnings on the uninstall?:

?

pi@raspberrypi:~ $ sudo npm uninstall node-red-node-sqlite

npm WARN saveError ENOENT: no such file or directory, open '/home/pi/package.json'

npm WARN enoent ENOENT: no such file or directory, open '/home/pi/package.json'

npm WARN pi No description

npm WARN pi No repository field.

npm WARN pi No README data

npm WARN pi No license field.

I also notice a file, package-lock.json,? in the home/pi directory.? Is that normal?

Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

I would remove the sqlite node and reinstall.? You might need to remove the sqlite node manually via the command prompt.? I think all the nodes in Node Red are installed though the npm manager.

I would try issuing sudo npm uninstall node-red-node-sqlite and let it do it's thing, reboot and try installing again letting the install finish with the GUI before moving on.? It will take a while.? Maybe 15 mins or so.

Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

Yes, everything was done from the Pi login.? I did the reboot but get the same error message.? Also, on user settings, under nodes tab, on the node-red-node-sqlite node, it reads "MODULE_NOT_FOUND" with "remove" and "disable all" buttons on the right.


Re: https://github.com/kylekrieg/Node-Red-Contesting-Dashboard

 

Jon, I've never seen that error before, so I'm going out on a limb here, but you installed Node Red and installed sqlite back end server under the same username, correct??

I would do a reboot of the Pi to make sure there isn't something hung up on your install.? Keep in mind, it takes around 15 mins to install sqlite node on a 3b+.

Re: Global variable initialized as number errors as NaN

Hi George,

?

I¡¯m late to the party on this conversation. Been hectic here (and they say you relax in retirement).

?

In the future use the debug node liberally to look at data at every point in the flow. In the debug panel you would see the payload as buffer, string, or number.

?

The debug node is also good for people new to Node Red so they can import a flow for equipment they have and see how each node affects the ¡°payload¡± as the data moves between nodes. It helps you understand how flows are written. Kind of like reverse engineering the flow. Everything in Node Red is in the public domain so plagiarism is OK ?

I looked over the flows again today.

I found a spot in one of the first flow function nodes that was set to flow.get instead of global.get.?

For some reason it worked for a while...? After changing the function to look up the global variable the flows started working again.

I created a new project and cloned .? I get an error "flows stopped due to missing node types" sqlitedb and sqlite.? In manage dependencies node-red-node-sqlite is on the list but greyed out and the only action is to "remove from project".? Under manage palett install tab, I search for it and it indicates it is installed.? I have tried to re-clone the dashboard twice with no change.?? I uninstalled and re-installed node-red-node_Why can't it find the node types?
Node red just installed yesterday on raspberry pi 3b+ with new install of raspberry pi os.? I followed install instructions in? install.md file at github.

Re: File /!1! Flows by Type/SVG Based Flows/Tuner Sweep.json uploaded #file-notice

 

Thanks, Bret

It would be easy enough to add Antenna information to the Tuner Sweep Dashboard, but for now, I think it would take away from the Tuner Sweep's KISS approach. ?Dave, what do you think?

Our next big idea is to have the frequency bars change colors to show the SWR levels and other stuff.....I sent Dave the HTML code, and Dave is working out the details of the color schemes and "other stuff". ? ?Stand by for the next update.

Re: File /!1! Flows by Type/SVG Based Flows/Tuner Sweep.json uploaded #file-notice

 

This looks very good indeed?and really takes advantage of the Capabilities of the Tuner Genius and a huge thanks to you Alan and Dave.
I was thinking maybe if there was a way to add the Antenna Genius Antenna selected to show in the Flow somewhere? and there could be a way to step through the Antenna ports?

Thanks again guys and I would be available?to test?your flows if you need someone to test stuff, Not a very good code writer?for sure but I can usually muddle my way through if I have something to look at.

Re: File Notifications #file-notice

 

Added the WO2X modified "Skinny" Bar Chart and made it the default chart. ?The "Fat" Bar Chart is available but not wired in:


Also, on the Tuner Sweep, added a display to show "Tuner Solution" status, with a five-second countdown. ?If you have a segment of frequency set up in the Tuner Genius, set to not tune (because tuning is not required) when the Tuner Sweep sequencer reaches this segment, the "Tuner Solution" will display, "Tuner Solution-None," and after five seconds, will continue to finish the remaining frequency sweep sequence.

Here is the new dashboard, with "Skinny" bars and the new Tune Solution status:



Here is the "Tuner Solution" status, when it encounters a frequency that has been bypassed in the Tuner. ?After five seconds, the sequencer will move onto the next frequency:



Dave, WO2X, will be making a video on his integrated Flex/Tuner Genius/Tuner Sweep flow set. ?That set has been posted in the Tuner Section.

Re: Global variable initialized as number errors as NaN

Thanks Mick,

? My issue is the other way around. ?

? My Node Red function is sending the Non Numeric to the MOAS II server.?

? I will try adding the node.status anyway to see what is being sent instead of the sequence number. ??

? I will also try hard coding a number to see if that confirms the problem is truly with my Node Red flow and not the MOAS II server.?

Thanks again,

George / W7GES?
