To simply run direwolf for you rigs run
Simplex VHF: `direwolf -c /home/$USER/aprs/Simplex-Support/direwolf_VHF-APRS.conf`
Simplex UHF: `direwolf -c /home/$USER/aprs/Simplex-Support/direwolf_UHF-APRS.conf`

Cross-Band: `direwolf -c /home/$USER/aprs/Cross-Band_Support/direwolf_MultiBands.conf`
Everyone's setup is different, Please ensure you have checked your
`PTT` method (If you're using an RPi your PTT method will be via the GPIO pins)
You can find the documentation on GPIO PTT here: https://www.marcelpost.com/wiki/index.php/GPIO_pin_on_the_RPi_to_trigger_PTT

`bash 1200b_RTL-SDR_APRS.sh` or `1200b-10m_RTL-SDR_APRS.sh` or `bash 9600b_RTL-SDR_APRS.sh`

_______________
Currently as far as I'm aware there is no easy way to get the RTL-SDR to run at 300 baud on Sideband for HF APRS
Short of using an SDR software such as "gqrx" and piping audio into a loopback device and creating a custom config
for decoding HF packets, This is unfortunely a limitation of the RTL-SDR software
