FLARM data volume depends on the connection

I'd heard that, but have seen any documentation of either those messages
or the FLARM additions to their IGC log files. IIRC both message sets are
regarded as proprietary/undocumented.

The FLARM message sets for traffic and collision warnings are very
well documented and used by at least a dozen other manufacturers
and software packages to display FLARM info. See "Data Port Spec":

See the "Sentence PFLAA" section for explanation that 19200 is
required to receive traffic information.

Hearsay is dangerous (and rampant on RAS)...
