    Well.....tried again, and this time it worked.   Maybe I did not get a full "copy".

    By the way, upgraded to SDR 3.17 and all went smooth. Everything including Maestro and multiple third-party apps worked out of the box.  W10 running on Mac Parallels.  Nice!

    Nice job!  Dave has some Flex IP stuff he can share and if you can follow the code, you can hack your way to the next part.  I just love the way I can rapidly prototype this.

    BTW, if using Chrome for your interface, you can shrink the screen size with zoom in and zoom out.  I run mine at 50% but if someone is vision impaired, they could go to 200% as well.

    If anyone would like copies of my flows, please email me at my call at arrl dot net. Allow a day or so to get back to you. Had major surgery today and laying in a hospital bed unable to sleep. Dave wo2x

    Thanks, Dave

    I am in receipt of your flows two weeks ago.  Thanks.

    Please get well soon.  I too had surgery and am in the end stages of recuperation.

    Back to the flows.  

    I was able to get your VITA49 flow working nicely.  I see that it receives the UDP broadcasts from port 4992 of the Flex.

    I have not been able to get your "flexradio" flow to work.  I see that the flow sends a request to the Flex API and looks for a response.  You then parse the response into desired parameters for Node-Red to process.  Your "flexradio" flow also uses port 4992, same as the VITA49.  Is that correct?   Node-Red is reporting an error message saying there is a port conflict??

    Get well and maybe we can talk more after your recuperation.

    Hi Alan They are sending me Down for a nerve block. I will resend the flows as I tweaked and fixed a few things. Make sure to edit the FlexRario flow to set the IP of the TCP send to match the IP of your radio, not PC. There were a few tweaks. I changed VFO A Freq to TX Freq. also added some stuff to the KPA1500 flow as well as fixed the Wake On LAN feature. Added power status and power off by tons as well. The DLI Web Switch was tweaked to increase the icon size to make it easier from a smartphone. 73 Dave wo2x

    Thanks Larry. Leave it to me to get a very rare infection in my artificial knee. Luckily I have found probably The Best doctor to deal with it. Now sitting in a hospital in Philadelphia, two hours from home..

    They removed the knee joint and installed rods, plates, and cement spacers until the infection is cleared. Could be anywhere from 3 to 12 months.

    I tried to load your flow and only the Dashboard Node was included in the file.

    Which flow and where did you load it from?  I have flows sort of scattered all of the place.

    Thanks, They are many, and MQTT is good to turn on your lights and/or radio.
    But it's to slow to read and send data in real time.

    Hi StefanI know of at least one contest station using MQTT. What part is too slow for you that you need sub-second response time?Can you provide some examples? Mike

    just got home from the hospital last night. I have plenty of time. 

    Send your flow you are having issues with and I will try to debug it. I really haven’t done much with Flex communications but can give it a try.

    OK. I will send you my flows.  This needs to be straightened out before I go any further with Node-Red.  Thanks -Joe

    Thanks for sharing Joe. 

    I haven’t ventured into the shack yet since I got home from the hospital but plan to do so today

    Next steps are remote audio, tuning the radio and sending CW via Node-Red.  Then I will have a more usable web interface. 

    I will publish my Node-Red code when I'm finished.

    It is awesome how these things evolve.  

    I added a 24V FAN to the cabinet running on a 12V circuit.  So, next I needed a fan control to turn it on and off.   Bam.. I have a thermostat that uses one of the relays in the KMTronic.  :)  It checks the Temp as recorded by the probe on the RPI every 5 minutes.

    I'm still working on smoothing it out.  I need to understand how the high and low pass filters work.

    I’ve been doing a lot of remote operating over the last 1 1/2 weeks. I have been using the iPad and Bose earbuds. Then bringing up Node Red GUI on my iPhone for monitoring and control of ancillary equipment. Node Red has been flawless.

    If a solution for audio from radio to Android phone can be easily cobbled together then radio control and operation from an Android phone is doable. Don’t get me wrong, it is not going to be a replacement for Marcus’s excellent SmartSDR for IOS but a fun project none the less.

    Just a thought.
