[amsat-bb] Re: AO-7 lost track

[Clayton Coleman]

The method to positively confirm AO-7's mode is to try working the
transponder.  If it doesn't work in mode B, it's probably in mode A.

Stations worldwide post almost each and every day the status of the
mode on the website http://oscar.dcarr.org (as pointed out by WB3CSY's
email.)  A quick glance at the site should reveal that presently it's
in mode A and tomorrow will be in mode B.  Actual satellite users post
the status.  In my opinion it is a reliable indicator.

It is a mystery to me why there is often so much discussion over the
mode of AO-7 when the 24-hour switch has been going on for many years
in the exact same manner.   You can search the AMSAT-BB archives and
find lots of information on this topic.  If scheduling future DX
contacts is a concern, keep a close watch on the current time of day
for mode changes and base your predictions on that, taking account
when AO-7 is next expected to enter eclipse.
