FLARM for SAR

QUESTION: I recorded the NMEA output of the PF with my LK8000 software.
Do you know of any software or technique for playing back the NMEA
output into the PC simulator of my LK8000 so that I can see the FLARM
information and warnings?

Do you mean:

1)Can I capture the NMEA stream as it is being read by LK8000 so I can
replay it into LK8000 again at home.

2)Does LK8000 record the PF data in its IGC log so it can be replayed
later or examined by the FLARM range checker?


If you mean (1), I'd guess the only answers would be to use the PF's IGC
log (I can do that now with my LX Red Box FLARM and, no, I do NOT have
the IGC log certification firmware installed, just an SD card slot)
instead of the LK8000 log, or to buy, borrow or build a gizmo that is
connected between the PF and LK8000 and that records the NMEA sentences
as they flash through it.


OTOH if you mean (2), I don't know the answer, but there's an easy way to
check if the FLARM contact data is being captured by LK8000. Read the
LK8000 IGC log into your PC and open it with a text editor such as
WordPad. Then scroll down past the heading stuff until you find lines
starting with B. If FLARM contact data is being passed through to the IGC
log you'll see a *lot* of lines throughout the rest of the file that
start with LFLA followed by 36 characters of complete gibberish. In a
FLARM IGC log there is around one L line for every two or three that
start with B, so I'd expect something similar from LK8000 if its logging
this stuff.

Normally an LK8000 IGC log doesn't contain any L lines.
