I did hear that it does not work so well with the older cavity type Xponders like mine and was wondering if anyone has had an issue with this setup?

I'm guessing that this was to prevent mid-switch codes from being transmitted?
For example, squawking 1200, issued 0441--
interim codes briefly transmitted : 0200, 0400, 0440, finally 0441.

1). Anonymous Mode does not go inactive in 2020. Period. 978 UAT will still fully support it. Prove otherwise with documentation.

2). Anonymous Mode is accomplished through an onboard device randomization of ICAO code and cannot ever be decoded to a unique aircraft indentifier on the outside. It is impossible by the very method of operation. That's why it drives the FAA control freaks nuts. Prove otherwise with documentation.

3). All cerified uAvionix ADS-B devices such as the Skybeacon and Taikbeacon are out only. So what's this about them missing targets on your screen? They can't provide any onboard information at all. They are out only. The Echo does both but that unit is experimental aircraft only and even then has updated software fix for "in". Prove otherwise with documentation.

4). Mexico has no mandate. If you think they do, then you have been listening to the likes of the FAA and the marketing department of ADS-B manufacturers such as Garmin. Same no mandate goes for but one area of Canada. We have Mexican customers who scoff and laugh out loud when the subject comes up. They have zero plans to equip for Mexico and many of these customers are "in the know" politically in their country. Baja or not.

5). All the fancy GTX 345's, 345R's, Stratus ESG's, and L3 units will be uncompliant in Canada due to their lack of diversity. It's funny but the lowly GDL-82 amd GDL-88 offer diversity but they are UAT not 1090. And in the case of the GDL-82 it won't even support a Mode S transponder or any kind of 1090 Mhz. What are Candians going to do about NavCanada mandating diversity based on a sattelite system just because they are a major investor in the sattelite provider company?
