Log file / location to show what chans are active in multi channel mode near real time

[KS4EC]

I am building a semi headless feeder box for our local ham repeaters and am looking for a way to display channel status on a small display on the front of the box. Is there an easy way to tell what chans are active, like the waterfall display.

I am experimenting with an i2c LCD display as the front panel display. In the end there will be 34 chans across 4 SDR's so I was thinking of just putting the chan number with a "*" under it to display activity. I may have to reduce the number of chans to avoid buffer issues, but that's another issue. I use Python for the LCD display but I am not real good at it "yet!"

Thanks in advance - Rob

No such feature is currently available.

It would be a bit of a hack, but what about writing each channel to a file with split_on_transmission = true then use a python script to watch the output directory?

I think this would result in a file with a temporary file extension in the output directory whenever that channel is active, and that can be used to infer activity.

Interesting idea, as this is on a Raspberry pi and an SD card, do I need to worry about excessive writes to the SD card? I'll dig into the write to file option and sort out watching the directory.  I am new to Python and linux so Google will be my friend.   Thanks for the idea.

If you mount a tmpfs and use that for your output directory the “files” will be written to RAM and not the SD card

I've been using inotifywait to watch folders this way, works well.

That is cool, I'll have to try it as it might be a cleaner and faster way to do it.Thanks - Rob On Monday, September 12, 2022 at 03:02:46 PM EDT, HelicoptersofDC ***@***.***> wrote: I've been using inotifywait to watch folders this way, works well. https://unix.stackexchange.com/questions/323901/how-to-use-inotifywait-to-watch-a-directory-for-creation-of-files-of-a-specific — Reply to this email directly, view it on GitHub, or unsubscribe.
