[OZAPRS] Direwolf on RPi

As a guess I'd say that it's failing at the pipe into direwolf. Cron is not the best way to auto start programs. Now I vaguely recall some chatter on this a week or so ago and iirc there is a script included in direwolf source code for starting it as a systemd service (this way any permissions and users are better handled)

However my memory is not as reliable as it once was!

Good afternoon and welcome to my nightmare

Running the latest Raspberry Pi OS Lite 32 bit –previously  known as Raspbian Buster - on a Pi 3B+. Trying to auto-start direwolf at reboot. Wrote a cron job in nano using crontab –e

@reboot /usr/bin/rtl_fm –f 145.175M - | direwolf –c sdr.conf –r 24000 –D –

The file saved without error and assured me that the new crontab had been installed. Now at reboot, quick as a flash, nothing happens. No error message. Nada. Almost as if the cron job isn’t being run... or read... or something. I know the command line works, that’s how I’m starting it at the moment.

So what have I done wrong, or not done right? 🤔
