Hello all,
Can anyone tell me if the Azimuth of the station being called is available in the UDP messages from WSJT?  I've looked through NetworkMessage.hpp, and cannot find a reference to it there. Unless it is RX_DF or TX_DF.  I cannot tell what they are for...
I'd like to extract it in a Node-Red flow, in order to direct my rotator without doing calculations that have already been done.
Thanks...

Hi Randy,

sorry that information is not available via the WSJT-X UDP Message Protocol, the DX Gid that the Az is calculated form is available in the Status(1) message along with the home grid as specified in the "Settings->General" panel.

Ok Thanks for that info, Bill. I’ll go on to plan B...

Hi Phillip.  It is a coding environment as well.  It is different from the typical line-by-line structured coding that you may have seen for arduino or other environments.  In Node-Red, there are graphical blocks that you drag onto a working area, each having it's own functionality.  You then fill in some fields in each block to give it the details it needs to do its job, and connect them together in the logical program flow you are working toward.

I am an old-school programmer that is used to structured languages like C & fortran (that dates me!), VB, and things of that ilk.  It took me about 4 hours of playing with Node-Red to become enamored with it.

With Node-Red, I am currently monitoring and controlling my Flex Radio 6400, controlling my beam antenna with a graphical, map-based user interface, and controlling/monitoring a web-based PLC (Programable Logic Controller) that lets me monitor power supply voltages, turn things on and off with a bank of 8 relays, and monitor other status (on/off) of whatever I hook it up to.  And all with a simple to make, simple to use browser-based interface.
It is simple to make connections via internet, local ethernet or serial ports.

It really is a lot of fun, and useful for running my station from a different room, or a different state.

There is a ham radio node-red group on groups.io:  https://groups.io/g/nodered-hamradio
It has lots of flows (programs) that others have put together, and this was the starting point for most of my projects.  It is very easy to copy and paste other's work to your own node-red to get started.

Enjoy!

It runs in the node-red environment only.  For most people, they have it running on a Raspberry Pi.  They set it up to run automatically on restarts.  Typically, there is a timer or two to set off the program at appropriate intervals, or just once at the right time.  Mine runs 24/7 and attempts to listen to or make connection with the devices periodically if they are not online already.
I've read that  an always on micro such as the PI is better than Windows because of this.
Besides ham radio stuff, it is also useful for other home control projects which would typically be running 24/7.

Oh, hate to reply to my own message, but the cool thing is that a program created for node-red on one platform (Linux/Raspbian/Mac/etc) can be easily copied to another platform.  At most, if you haven't loaded some functions that are used in the imported program, you would have to install the missing functions from the new platform node-red.
Much easier than finding missing libraries in C or other languages.
