I hadn't heard anything about this & didn't get a notice from uAvionix. Thanks for the heads up.

I missed it till I asked why my altitude when it ghosted was off by 1,000'.  Looked into it and the original scheme was to use Mode C altitude and if Mode C isn't available it uses a previous value.  The add on encoder is very light and small, comes with a wiring harnass and uses ambient pressure.

I was too getting that request from the controllers for a while.  Then someone here posted about the Echo free upgrade.  It took a few months to come in, but it was simple to install and then upgrade the software.  I haven't been asked since by a controller and I checked with the app on my phone and it was reporting pressure altitude.
