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.

>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.
