What could this be?

What ever it is its sending a lot of messages;

ADF9CE and ADF9CF

When I click on them they both say N/A or unassigned

The age of messeges keep staying at like 0 to 1 sec.

Can be local stations for testing/calibration.

I have them on my device in Germany from time to time too with other HEX codes.

Oh ok cool. Didn’t know this.
