The last time I looked thee only one sending these were dig-ned, as I recall
they were sending EQNS that were all zeros at that time.

You don't mention how long you save these, looking at each these for raw data in
last 24 hours:

So, out of the list of 35, only 5 have sent valid data in last 24 hours, all are
digis. The last time I asked about this, the digi-ned people said they had their
own software to view the data and needed no support from findU. No one using
these has ever asked me for support.

Personally, I would need to see more users of this format bedore I went to the
effort of adding these beacons coefficients to findU...
