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.

73,

Mark N8MH
