Noel, are you sure about that? If I recall correct, this parameter is optional for mode S users, and Flarm defaults to Flarm ID if you don't supply one, which is different for each unit. This is the first time I hear this explanation.
But I agree that one must configure the unit first. A friend flew without configuring his unit and we could only detect each other when circling together, I am not completely sure why. Also his display showed constant transponder alert from his own transponder.

Ramy - Maybe they fixed this in newer deliveries... I was warned
about this (along with many others) by a west-coast FLARM dealer; and
was able to confirm that two PFs in close proximity with default
settings didn't see each other; but that was back in June. I haven't
had to touch the config on my PF since Nationals so perhaps my info on
the defaults is out of date (would be a good thing if it is, I
suppose)!
