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

Using the WO2X Tuner Genius Flow as the TCP stream and polling source, I built a SVG based Flow that will sequence the Tuner Genius through a range of selectable frequency range, and step width, to "Teach" the Tuner Genius the tune solution for each frequency. Results are displayed in a SVG bar chart. ?Here is a screenshot of the results of teaching my Tuner Genius the solutions for a G5RV antenna, across the 40 M band, ten steps. ?Also, attached is a video of the Tuner Genius "Learning".  Because the Tuner Genius only allows three TCP connections, I used Dave's Tuner Genius flow to move the TCP stream to my flow. ?In my case, I used MQTT nodes, but you could substitute "Link" nodes too. Here are the required connections:  Alan. WA9WUD

Plagiarism at its best!
As Ron said, customizing any of the flows you find to fit your specific needs is why Node Red is so flexible.

Ron, I realize my idea conflicts with your separate 'standby' drive control allowing high txcr pwr in standby.
So this is just my custom fix for me, as I like the drive level to be set by power zone in either Operate or standby.
I would never use txcr high power via the amp with the amp on. I have done this with MP 200w in the past > amp off,
but SPE handles that power in/out to default Ant 1. I find your band control useful as I have higher gain on some bands.
Sorry I have asked for something that messes up your original design. I just share my ideas.
Thankyou

Welcome to the group. ?You can install Node-Red on most any operating system, including Window and Mac.
Most prefer to use Raspberry Pis because they just run in the background.
I run my Node-Red on a Mac, Window and Linux
The Node-Red home page is an excellent resource for basic instructions, including loading Node-Red on the various platforms.
??
I can never find the Mac and Window instructions, so just "Google", "How to install Node Red on a XXXXXX".
Dave, WO2X has an excellent set of instructions in the group file section, for everything you need to know to set up a Raspberry Pi Node-Red.

Re: Node-Red Totally Newbie
Juan, welcome! I too along with many in the group have Flex radios although?the group is not?Flex specific. You will find different approaches to shack integration with Node Red. Some of us?with?Flex radios integrate?Flex SmartSDR functionality into Node Red. I personally do not. I choose to continue?use of SmartSDR for my Flex 6600 and use Node Red to manage my other devices so I in effect have 2 panes of glass (and a few more if you roll in WSJT/JTalert). My Node Red dashboard (shown below) has left to right: - DLI Power Switch control (8 120V network controlled outlets)
- Band activity (I should remove this as I find it of little value)
- My SPE Expert Linear amp
- My LP-700 station monitor
- Ham-IV rotor controller (2 dashboard elements, buttons and map) controlled via an ERC-4 module in my control box
In my case I do not have a remote shack. All equipment is local. If you search the forum and look at the various screen snapshots attached, you'll find all kind of creative Node Red dashboards. I've been using Node Red for about a year and have found this group to be very supportive and helpful.
So to answer your question on "what to do first", figure out what devices you want Node Red to manage. The start with them, one at a time, and roll them into a dashboard. Extend the dashboard as needed for other devices you choose to integrate.
If you need help installing Node Red, Kyle, AA0Z, has an excellent series of YouTube videos on installing Node Red on a Raspberry Pi (RPi) along with some easy flows to play with.

Hello everyone and greetings from Guatemala.
I have a Flex 6600 (with an extra toy in route) and I have been hearing about some of the things that can be done with Node-Red for amateur radio, but unfortunately I¡¯m a complete newbie to programming at all.
What will you suggest me to do first ?
Well besides been on this, the right group.
I have a Windows 10 PC for amateur radio related but also have an iMac. Can I start with either one ?
In advance thank you for your time, support and patience.

Adrian, My flow simply provides PC control of the SPE. The front panel allows power level changes while in operate mode and I see no reason to enforce a restriction in the flow. Feel free to add an interlock to the power level portion of the flow to ensure the SPE is in standby. As to band changes, the flow is totally band agnostic as it is the exciter that initiates band changes (assuming CAT/Band data is available to the SPE). In fact, my flow does not implement band change capability. The band "icon" is a status indicator of the SPE's band setting and not a "button" that initiates band changes.?
I have considered adding the two following features (per the future enhancements section of the read me) and I could easily add an interlock for power level (low, middle, maximum): - Disable hot switching from standby to operate while in TX mode
- Disable hot switching power on to power off while in TX mode
Ron WB2WGH
Ron, Yes that was my question how to allow it in standby please?
It is smart to do all band/power zone changes in standby to ensure the
amp is not keyed before drive and antenna have been set.

Adrian

Adrian, You may need to customize the code. Look in the function node "Define Exciter Drive Power"' You will find a table (see below) that sets the drive levels for standby, low, middle and high settings. The code defaults to the first column in the table for standby operation. It looks like you prefer to leave the SPE at the operate drive level rather than the standby drive level.? The following code snippet?should do what you want. In a nutshell, the select/case statement is commented out to ignore operating mode and one additional statement is added to set the power level. --------------------------------------------------------------------- /*? ?Optionally comment out VVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVV switch (mode) { ? ? case "S": ? ? ? ? slmh_index = slmh_string.indexOf("S"); ? ? ? ? break; ? ? case "O": ? ? ? ? slmh_index = slmh_string.indexOf(pwr_level); ? ? ? ? break; ? ? default: ? ? ? ? slmh_index = -1; ?//infaclid mode returned, flag for zero power ? ? ? ? break; } ?Commented out ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^? ?*/ slmh_index = slmh_string.indexOf(pwr_level);? ? ? ? ? ? ? ? ? ? ? //Add this statement to force mode agnostic drive levels for Low, middle and maximum ---------------------------------------------------------------------
var drive_pwr_table = [
// ? ?Standby ? Low ? ?Middle ?High
? ? [ ?100 ? , ? 1 ?, ? 2 ? , ? 3], ?//160M
? ? [ ?100 ? , ? 1 ?, ? 2 ? , ? 3], ?//80M

Ron, I have noticed that I cannot change drive auto with power level change in standby, and only in operate.
This is risky when you want correct drive set before setting amp in operate.
What can I do to change & test please?

Adrian, the exciter drive level is determined from the band and drive level table which had 4 settings per band (standby, low, middle and maximum). If tou want the standby drive level to be the same as the operate drive levels, you'll have to tweak the logic to make it operating state (standby, operate) agnostic and set drive level based on power level setting. If you need assistance, let me know. Ron WB2WGH?

I built a SVG based SWR Sweep Flow. ?This version is set up to work, stand alone, as a Non-GUI Client, with a Flex Radio, Slice (0). ?This means you need a GUI client connected to the Flex Radio, so the Node-Red Flow can command the radio. The basic SVG SWR Sweep can be easily adapted to other radio types, that Node-Red may command the "Tune" and the "VFO Frequency". ?E-mail me for help if needed. Attached a video of the flow scanning my G5RV antenna on 40M. Here is a screenshot of the final scan results. Alan. WA9WUD

Re: Remotely monitor RPi devices
Ron,
I looked at that option but its a bit too complicated for my needs... I just completed the creation of a Python script and using the NR Exec node am able to monitor the system variables for all of my remote RPi.? I'll upload the zip file with the script and flow in the next day or too.

Re: Remotely monitor RPi devices
Mike, MQTT seems to be popular for Node Red inter-host communication as is evidenced by many of the threads here. I have not needed that capability so have not delved into it. At some point I'd like to see your solution as it might be a good learning example. My Python experience is limited to test equipment (IEEE 488 GPIB) scripts. 73, Ron WB2WGH?
[Edited Message Follows]
Ron,
Thanks... I've looked at that solution.? He installed NR on all of his RPi and used the MQTT nodes to exchange info.? Its a bit too complex and high maintenance for me.
I found a way to run a Python script on the NR host which will remotely execute a shell script to obtain the system info.? Once I get this working, all I have to do is use a NR Execute node to run the Python script.? I'm going to give this a try and see how it works.

Got it worked out. Seems all of the script was not needed to open settings. Not out of woods yet but am trying to work it out. Thanks all for what you do.
