Oudie/Flarm alarm from my own ADS-B/Transponder

Thanks to 5Z and Roy B. for their help. I adjusted the FLARM configuration file:
-My config file already had "$PFLAC,S,OWNMODEC,0", but I noticed that I had:
$PFLAC,S,MODEC,1
so I set it to:
$PFLAC,S,MODEC,0
-Per Roy B. I cleaned the FLARM SD chip and put only the latest firmware update and the config file
-I also made some adjustments to the transponder configuration to correct errors found on the PAPR report. One of those was that the aircraft ID was missing the "N". I corrected that in both the transponder and also the FLARM.

I don't know which of these changes fixed the problem, but I tested the system yesterday and I am no longer getting the conflicts.

Thanks again for the help!

You are welcome. If the problem re-emerges intermiently, please let me know. Mine still does it once in a while. Yesterday in a 7.5 hour XC flight I got what I call the "chasing your own tail" alarm about 3 times that stopped when I hit the "dismiss" button. It seems to happen near a large Air Force base and a practice drop zone the AF uses. I have no idea why.

It was most certainly the aircraft ID.
But now you disabled mode c alerts all together. You may want to turn that back on.

I re-enabled mode C yesterday and when flying again got the continuous conflict alerts. In flight I managed to turn the mode C off in the Flarm and the alerts went away. Is there something wrong with my configuration of the FLARM or transponder/ADSB that is causing this? My ADSB set up was just tested and passed, and I just generated a PAPR report for the flight yesterday and it was clean. I updated both my FLARM and Oudie firmware this year, so they should both be up to dare. My FLARM config file is:

Try $PFAC,S,MODESALT,0

Why are you asking for it to look for every ADS-B target with 65 km horizontally and vertically (215,000')? You might be overwhelming it and this is a symptom.

Many of us depend upon configuration advice provided by the vendors.
I buy my stuff from Paul Remde (Cumulus Soaring).
Does anyone have concerns with how Paul advises to set-up the Flarm?

Guy,

Paul has been very helpful to us on several problems. I set up the FLARM per his instructions, and also the transponder that we bought from him (Trig TT22 with TN72 GPS). Of course I might have missed something...
