Alan,

Wow!? That's going above and beyond!? I have only taken a quick look at it, and only see a minor issue.? It appears that once the AUX is turned on (Green) that there is no way to turn it off.? Granted, I'm only playing with it via the dashboard (and I'm operating my shack PC remotely, so there is no hardware, other the the RasPi connected).

yes that's correct.? I did sudo reboot not shutdown (but will have tried that by the time you read this :D )

Yes I did do the restarting (even reboot, although I know it's overkill).

I have the spe utility running on my windows machine, I'm not aware on a Linux version.

Ill look again for a firmware update, and may try and see if using the remote serial interface works any different.

Thanks for all your help!

Read up on variable types.? There are very good tutorials on the Node-Red.org web site:

Many ways to get there.?

From the Inject, take that msg.payload and you can use a Change node to set the msg.payload to flow.x (or any other name).

Feed the msg.payload to a function node.

var y = flow.get(“x”);

msg.payload = (msg.payload * y);

return msg;

You could probably condense into single function node.?

Since you have only one Com connection to the RPi, you can try to just use the default port path:

/dev/ttyUSB0

Next, Dave, WO2X, said to test the SPE amp USB port by downloading the SPE utility. ?Make sure the SPE amp and the Utility work OI, that way you know your USB connection is good.

And last, another ham on this list had the same equipment and problems you are having, and in the end said he found a later version of firmware, that solved his connection issues.. ? ?I forget who it was, so maybe they will see this and jump in.

far as I can tell there's no config option for the baud rate in FRStack, and the amplifier is supposed to be auto-baud detecting...

I have found pasting the path to the "by-path" serial link into the COM on the FRStack "appsettings.json" config works well to link to the correct serial cable.

Three items to check.

- For the SPE amp, use a simple USB cable from the SPE USB connection to the Raspberry Pi.? If you only have one serial connection to the Pi, your port config should be good.? Otherwise, look in the "/dev/serial/" directory?for the name of your com connection

- Make sure the SPE amp firmware is up to date.

- In the FRStack Config file, select the correct protocol:
