Command-line calculator for Maidenhead- (QTH-, QRA-) Locators.
... something that would work off-line.
* There are also several GUI- (Windows-, X11-, etc.-) based calculators, but I wanted something for the command-line, something that could also be used in (bash-)scripts.
* The repository for my GNU/Linux distro has only one such a QTH-calculator.
--- This program has a few issues
--- Made worse by the adaption for Ubuntu, that removed half of its functionality
So, I had to roll my own. (Which I enjoyed anyhow.)
Perhaps also useful for others
