Unknown ID-TEST1234


#1

This image is from my Skyview display. I have 2 TEST1234 ident tracks with no heading/distance info nation with huge message numbers- 400,000 plus. See attached picture.

Any idea where these are coming from? My antenna location is marginal at best so the signal has to very strong to get to me.

I’m near Kansas City International airport, both Garmin and King Avionics are located within 30 mile also.

Check this external forum topic. They have kind of sorted it out.

As noted in the link above, they are beacons used for FAA equipment calibration. You will see these in the USA if you are close enough to the airport transmitters.
