set up a second GPS03 + icE1usb setup
As we have some strange GPS hold-over events in #5883 it would be a good idea to set up a second "identical" setup, i.e. icE1usb with RS422 board and GPS03 receiver to compare against.
I already have a icE1usb operating my OCTOI link at home with its internal GPS receiver right now. I also have spare GPS03 and one RS422 board and free output ports at my GPS splitter.
Let's set that up at some point.
