Re: Scheduling A Node Red Zoom Trainng Session?
I created a Zoom for this Thursday Aug 5th at 8pm Central if anybody wants to hop on and talk about Node Red.? We'll see if Dave or Alan can stop by to give us some fire power.? I think we might need to have another Zoom for the other parts of the world as Dave talked about in an earlier string.?

Re: Problem with TGXL flow
I¡¯ve re-read your message Les. I am testing this now. I do not think it is a FlexRadio flow issue. ? Standby ? ? Dave wo2x ? ?

Re: Problem with TGXL flow
Hi Les, ? It is actually working as designed. I will explain. ? The Node Red server as I have designed the VITA49 and Flex Radio flows is designed to be running 24x7 and be running before a SmartSDR client connects (SSDR for Win, Maestro, SSDR for IOS, or MAC). If you reboot the Pi, then disconnect your client to the radio and reconnect, it will work. ? Now, why did I do this? We found if you send TCP commands to the radio while it is transmitting will cause ¡°popping¡± in the TX audio. You can hear it on SSB, see it in waterfall on FT8 and mangled CW character(s). The FlexRadio flow only sends the subscribe TCP commands when the client first connects. I used to send them every 5 seconds and wondered why I had the popping on FT8. Took a while to figure it out. ? I could probably look at client connected global variable and wait 10 seconds. If Client Connected does not equal 1 I could have it send the sub commands again. Let me see if that would be feasible. ? 73 Dave wo2x ? ?

I¡¯m definitely up for a zoom conference! I also have the ?Keyestudio 4 relay board mounted on a RPI 3B and node-red installed, ready to customize.?

Re: Scheduling A Node Red Zoom Trainng Session?
Dave & all,
So I bought a Pi on Amazon, loaded raspberry OS and node-red.? Imported a couple of Pi-specific flows (temp, CPU/disk usage) to see how they worked, and like I am "now what?"? I could really use some help as at this point I don't have a clue what to do next.
Retired in FL and can participate most any time except mornings as we have activities with grandkids.?
THANK YOU for offering this training.

I use my Desktop Smart SDR for the Satellite station and my Maestro for the HF Station. ?Satellite tracking is from SatPC32 which provides doppler connected uplink (TX Radio Two) and downlink (RX Radio One). ?Also, SatPC32 can be controlled from the Flex Radio. ?All CAT work is done via the Kenwood formatted CAT messages. One issue was, my Smart SDR, remained "tied" to SatPC32, and I could not disconnect the CAT from a remote position to allow the desktop slices to be re-purposed, while I waited for the next Satellite. ?I could not find any Flex API or FRStack commands to temporary disable Flex CAT or the SatPC32 CAT VFO mode. So.....Node-Red to the rescue. ?I now have a "CAT Control" button on my dashboard. ?I can also control CAT status from other flows, to automatically set up / disable CAT depending on satellite position in the sky. ?Here is my Satellite Screen, with the new button:  The flow works by setting up Flex TCP CAT ports tied to Flex Slice A (downlink) and Slice B (uplink) (Thanks, Dave WO2X for suggesting this concept).  On the SatPC32 side, I select unique port numbers for each radio (radio one: downlink, radio two: uplink)  Next, using "VSPE Manager", set up a port pairs, to match those selected in SatPC32, and a TCP Server, connected to the opposite port pair and to send out the serial connection via TCP:  Node-Red is now set up to connect the two TCP streams of Kenwood commands, one to/from Flex CAT and the other to/from SatPC32. ?A "Gate" node is used to "switch" the stream on/off.

Description:
Node-Red Flow to allow remote control of the Flex CAT to SatPC32 Satellite Tracker CAT for two slices (radios). The concept is adaptable to other situations where a remote Flex CAT enable/disable, to an external application (via TCP), is desired. Thanks to Dave, WO2X for his conceptual input. Requires use of virtual ports and TCP server, set up using "VSPE Manager".

Re: Changing font color by value of msg.payload
Yes, if you connect to the radio as the PG XL client and format the data correctly then technically you can get amp info to show in SmartSDR.
Good one Warren!

(Acutally was sorta QRT for? while taking care of some medical issues and my 92 yr old mom).
I couldn't get the flow to work at all when I hooked it back up to the PI. Alan helped me get the serial (USB) ports talking, and then I realized I needed to update some things for the new firmware. Got it all running in short order after that.? For a full-sized screen, the dash is great. But I'd like to make just a small touch screen to display PWR OUT from the amp, and the SWR, as well as a button switch OPERATE/STANDBY. I could do it on a small Pi and sit it next to my Meastro.

Re: Scheduling A Node Red Zoom Trainng Session?
Dave ( & Rusty)
Even though I don't have a Flex ( I am currently running a Kenwood TS890)? I am led to believe that much of the Kenwood serial command structure is very similar. I would like to at least sit on on the zoom call if possible,. Rather than try and juggle multiple schedules I'll just try and tag along on what ever you guys decide. I am retired with few outside? commitments. I am in the Floridian same time zone a Dave WO2X

Re: Changing font color by value of msg.payload
Oh.....RUB IT IN...hi hi. I'm very happy with my little KPA500. It really has enhanced ham radio for me. All those Asian countries that had been out of reach are now in the log. Just about to cross the 200 DXCC mark. Very pleased with the station. No big yagi or tower here, just a EFHW up 50'. When I first installed the amp, I was having some RFI issues, but with some tweaks to the feedline length and a LPF, it's pretty much gone.?
I wonder if there is an API for sending data to the Maestro.....would really like to send PA output power and SWR to its screen.
