Found a few descriptions on Google:

    agrello relative bearing quality

I want to get into playing with RDF units, but it's not at the top
of my list yet.

I'll work on the Xastir RDF code just a bit more and have it spit
out only strings that _might_ be Agrello format.  Doesn't mean
Xastir will be plotting vectors for them yet.

So far I've found descriptions of these three:


    Agrello format:  "%AAA/B<cr>"

    "AAA" is relative bearing to the signal (000-359).  Careful
    here: At least one unit can report in magnetic instead of
    relative degrees.

    "B" is bearing quality (0-9).

    "%136.0/9"
    "%136.0/8/158.0" (That last number is magnetic bearing)
