Define this radar code ??

[elizabethreeder]

I've been tracking flights around my area in southwestern Ontario in Canada, when I clicked on a yellow plane icon, this is what it says for what the radar was tracking it, R273c, Anyone can identify this oddball. I have never seen any alieas radar of this nature, not sure if it is just an annomoly or what.

This is indeed an odd one! We believe this is a radarcape without a sharing key, and it will eventually disappear. However please note this is simply our best guess, as we would be unable to confirm this with certainty! I hope this helps clarify this a little

I'm pretty sure the "R" codes are temporary ones until the new feed gets assigned a permanent one.

Edit. Just found the post:

There was one of these R codes around Melbourne, Australia for the best part of 12 months a couple of years ago. One day it just vanished but I have no idea what it changed to, if anything.
