"""
To use DMR and YSF, the digiham package is required. You can find the package and installation instructions here:
https://github.com/jketterl/digiham
Please note: there is close interaction between digiham and openwebrx, so older versions will probably not work.
If you have an older verison of digiham installed, please update it along with openwebrx.
As of now, we require version 0.2 of digiham.
