Hi Tom,
For VO-52 it is best to use LHCP (2 meters) for the downlink and RHCP for
the uplink (70 cm).

AO-07 has linear antennas but LHCP seems to be best most of the time for the
downlink.

It all depends upon the satellite - not necessarily on the mode.

Adding switching is a good idea.

Emne: [amsat-bb] Circularity question.

Do I go RHCP on the downlink and LHCP for the uplink or vice versa for 
Mode B?  I may add RH/LH switching later but for now my new antennas 
will be fixed.  Is there a reference that speaks to this issue?

73,

Tom K5VOU
