This is a very simple call/packet router for Homebrew Repeater Protocol. It will forward traffic from any system to all other systems configured in the hblink.py configuration file. It does not check for call contentions or filter TS/TGID combinations. It should really only be used as a proxy to hide multiple Homebrew repater protocol systems behind what appears as a single repeater, hotspot, etc.
As is, this program only works with group voice packets. It could work for all of them by removing a few things.
