Thank you for the reply and for troubleshooting this.
I have tried out PyMultimonAPRS because I was experimenting with the RTL
dongle, SDR, gnuradio, etc.
It looked like a nice application to have.
I will forward this information to the "raspberry_pi_4-ham_radio" list
on yahoo where the information on this project came from.
BTW. In this setup, it uses MultimonNG but I don't know the relationship
between multimon and multimonNG.
