The FAA removes the ID when the radio facility is out of

signal being broadcast [maybe part of testing or trouble

at low volume. The monitoring decoding by the hardware is
very nice.
The TEST case brings to mind an amusing story. I was in the
backseat while my wife and her instructor were flying around
trying to track the EMI VOR. They had the IDENT volume up
so I could hear it sending. I finally had pity on them
and let them know it was sending TEST. Shame on Margy, she's
a HAM radio operator from the days when she had to copy CW
at more than twice the rate the VOR sends to get her license.
