Hello Ib,
Thank you for the report.
The transmitter shuts off (for about a second, maybe less) after 2 minutes, even if people are talking with a 67Hz tone. So, a new 120 sec period will not start until the current one ends.
The bird was loud this morning! Lots of activity for an early (6:15 am local) pass.

Hi Drew, I listened to a pass with AOS here at 0649 UTC. AO-51 turned the TX off as it shall - but it was soon put on by someone. I did not time it.
A question: If people use a 67 Hz tone before the TX turns off will that start a new 120 sec. periode ?

PL is on as of about 2215Z. Before LOS I heard it drop twice for a second or two until it heard a valid tone again. This will happen about every 120 seconds. Reports are welcome, especially from remote users/areas.
