From AMSAT-bb (http://www.amsat.org/wordpress/pipermail/amsat-bb/2016-November/061297.html):
The AMSAT satellite status page at http://www.amsat.org/wordpress/status/ indicates
that as of the morning of 11/25/2016, AO-7 is once again entering eclipse
each orbit. This means that the 24 Hour mode change timer is interrupted
each orbit, and the satellite will be found primarily in Mode U/v (aka Mode
B).
As the satellite is powered solely by the now 42 year-old solar panels, it
is very sensitive to strong uplink signals, particularly CW. Users should
closely monitor their downlink for excessive chirp, warbling or “FM’ing” and
reduce power as necessary. More information including frequencies can be
found at http://ww2.amsat.org/?page_id=1031
