Armbian Buster on Rock Pi 4 longer has libgfortran3 library.  Other versions of Buster do have it.  Has it been superseded or just went missing?  The ham radio weak signal programs use a lot of fortran modules.

 

Thanks

Here https://packages.debian.org/search?keywords=libgfortran3 is evident that is not a part of the standard Buster package base and Armbian never shipped such library as a part of a standard base. This way should work: https://backports.debian.org/Instructions/

why not updating the app to

libgfortran4 - Runtime library for GNU Fortran applications

or

libgfortran5 - Runtime library for GNU Fortran applications

 

which is available in buster?
 

 

I got 

deb http://httpredir.debian.org/debian buster-backports main contrib non-free

in my /etc/apt/sources.list, but no version 3
