Could be because the ATC facility isn't using ADS-B data yet and can only see your transponder (Mode 3/A code & Baro).

Personalized service from the Fed, sincere smile included

I got my report back from Jim 10 minutes after sending the email. Everything appears to be in working order.

For the record I have a 430W and a Skyview system with the Trig transponder. When the Skyview capability became available, I updated my 430W firmware, added a serial output pin and connected it (with the resistor) to the pin on the transponder.
I don't remember the settings used but I do know I just followed the Dynon install instructions. It seems to be a successful recipe.

I have a 430W and GTX330ES. I just got the report back from Jim and I am failing on:
NIC - 100% fails
NACp - 100%
NACv 100%
NIC-SVT 100%
NACp-SVT 100%
VAL - 100%

Geo altitude also fails 91% of the time.

For NIC, they are receiving 0 - unknown. For NACp, they are receiving 0 - >= 10NM. for NACv they are also receiving 0 >= 10m/s

I need to go back and check but I am pretty sure my 430W is set to send out ADS-B + and GPS integrity is set to IE-7. I do believe my GPS X OFST and GPS V OFST are set to the default of unknown. I will try changing those.

On a portable GDl-39 I do get TIS-B information and the other areas on the report do pass. It shows that I am sending a SIL of 3 and a SDA of 2. The GVA is a 0 though.

Does anybody have a suggestion?

Verify you're on ADSB+... I have my doubts..

Hmm--nothing on purpose! Any idea what might have gone wrong, per the post 5/17 numbers?

Bob, I'm on the wrong side of the FAA firewall so can't dig any deeper till tomorrow afternoon (meetings in AM). If no joy will engage our cert folks for guidance.

Do you have the newest software (I think it is version 5.1) in the 430W? You must have that to work properly.

Disappointed to hear from jdm117 this morning that my report has not changed materially after making the recommended changes.

Had my 430W software updated to 5.1 and changed the setting to ADSB OUT +.

Changed the 330ES setting to ie7.

The 430W seems to be communicating properly with the 330, because the "no adsb" message in the upper left corner of the 330 goes out as soon as the 430W come on line. Additionally, I still get good TIS info on the 430W screen. Any Garmin gurus here that can suggest any other settings I might have wrong? It would sure be nice to have a definitive list of the settings necessary for ADS-B out.

I think I have it correct. On the 430W Channel 1 is going to my portable GPS and channel 2 is going to the 330ES. On the 330ES channel 1 is from my encoder and channel 2 is from the 430W. As ytou can see I have SW 7.02 on the 330ES and main sw 5.03 and GOS sw 5.0 on the 430W. I will double check tomorrow that RS232 port 2 on 430W does connect to rs-232 port 2 on the 330ES.

ANy other suggestions?

It looks like I am having the exact same problem. Is there any need to turn off TIS-A between the 330ES and 430W and only use the TIS-B from ads-B on a GDL 39 or similar receiver? Are there any other setting that can be set?
