I have the good fortune to have a nice ground rod just outside my basement wall, which I connect to with the ground for both Blue and Red.
When the RED board was in testing state on my dining room table I had either no ground, or grounded through my home's electrical system.
Admittedly, it is a single family dwelling with good electrician's installation may have made this a more dependable ground than what someone living in an older building or apartment where the ground had been patched around from revision to the home or apartment over time.
As an additional point, one of the longer functioning stations with an excellent history of strike participations uses a house ground for his station.
