When you add the encoder unit to the EchoUAT, you need to apply two software patches to enable the encoder. They can be installed using a web browser connected to your Ping unit via WiFi.

Additionally, if you have a digital transponder with a serial out port such as the Sandia Avionics STX-165, you can connect to the transponder and get the squawk and Bario Alt outputs directly from the transponder via the serial port. That negates the need for the uAvionix encoder. I had the installation in my KR configured that way and it always passed the FAA PAPR reports flawlessly.

Thanks Jeff for this info,

You may know now that uAvionix has stopped making the EchoUAT so there are very few in any pipelines.  I wanted one to install in an LSA that I am working on.    I understand that they MAY be offering something like it in the future with the fix included but no time promise. 

Surprisingly every spot I checked was out of stock but with a connection I found that GRT avionics had a few in stock that they pair with an antenna unit that they have made to do what uAvionix was offering in the past.

I talked them out of one of the last ones on the shelf so this update is something I will need to do.  I will be buying the SkyFYX Ext  antenna from them for my system.

Have you heard anything special to do with these two units together?

Thanks,

I know a number of you KR fliers are using uAvionix EchoUAT ADSB in and out units in your planes. In January, I received a notification from uAvionix that they would be offeringcredit on the Echo UAT units towards another purchase, or send a free altitude encoder to fix an issue with ongoing "Bario Alt" high error rates in the FAA PAPR reports. 2 months ago I was notified by the FAA that I had 45 days to repair my ADSB unit or it would be blocked, effectively denying me in-flight weather updates and access to Class B and C airspace. Sure enough, sometime in the last month my unit stopped receiving inflight weather, so must be blocked.

Yesterday I finally received the free encoder to add to the Echo UAT unit. This morning I installed the tiny solid state encoder and applied two software updates from my phone via wifi to the EchoUAT unit. The encoder comes with a plug and play wiring harness, so the installation is dirt simple. No harness to build, power to run or wiring to be done. After installation, I flight tested the aircraft, then pulled an FAA PAPR report and found no errors reported on my unit. Now to get the FAA to unblock my unit and allow me to start getting weather updates again.

If you have not contacted uAvionix to request the free encoder for your EchoUAT, you can make the request on their web site at <https://uavionix.com/echouat-update/> You will need the specific model and serial number of your unit, but just fill out the form and uAvionix will eventually get the encoder to you. I found the update to be simple enough that I installed the encoder and software updates in all three planes this morning.
