I installed 17.3 in my dual HDX. Now, the traffic targets are dropping out, so much so that they're visible for about 30-40% of the time. I haven't checked the weather screens or the TFRs.

Questions:
- Am I the only one seeing this loss of ADS-B Traffic info?
- I see talk about an update to the transponder: Is that something I should also find and load? (or is that part of the overall 17.3 package?)

According to the instructions the transponder update is included in the 17.3 package but you explicitly have to perform the update to the transponder in the transponder menu of the Dynon, this is not handled automatically

Might want to wait a bit. Most members of the forum don't come here all the time. Even us 'regulars' can sometimes go days without visiting.

We have not had reports of this so far with 17.3.0. We do get reports from time to time of traffic dropping, but there have been some fixes for that over some of the recent system updates. So far it doesn't sound like others have noted any changes there with this one, but as Rhino did note, it is early since the version release.

Question 1: What version were you running prior to updating to 17.3.0? Were you on 17.1.0 or an earlier version?

Question 2: You noted the transponder update, which can be done but I doubt that it's related, but have you updated your ADSB module lately? You can see if the unit itself has an update present by going to SETUP > ADSB STATUS > enter this menu and if an update is available, it will prompt you in the menu to update it (in yellow). The most recent ADSB module update was only for the ADSB-472 module. So if you have an ADSB-470, the last update did not apply.

The update is only for 262 transponder correct? Not sure if scrollF4 has 261 (US) or 262 (outside US)

It's for both the 261 and 262. I have attached the service bulletin from Trig that this update covers for reference for the background on it.

The service bulletin doesn't discuss the software update process with SkyView. This should be used simply as a reference for the reasoning behind the update and what changed. Their process to update is different than our version.

Thank you, I was going by the update and it only shows -262. I wasn't going to update to 17.3 since nothing applied to my configuration, now I will.
