OPUS post processing and static collection methods

I collected static data for the second time and again did not obtain a solution from any of the 4 control points when uploaded to OPUS rapid static.  I am using an R7 with a zephyr 2 gnss antenna.  The area I am collected is a somewhat clear area within a deciduous (no leaves) wooded area.  At least 10 satellites were tracked the entire time for all of the collection sessions.  I am pondering three things:  1. Should I try to collect for a longer period - maybe even 2 hours or more and upload to OPUS static processing?  2. Should I be using a zephyr 2 geodetic gnss antenna?  3. Is there software out there that will enable me to "weed out" bad collection epochs?  I have tried collection at 1, 5, 10 and 15 second invervals for over 30 minutes each control point.  Any input would be greatly appreciated! thank you.    All points come back with 1 of 2 of the below error messages from OPUS:

 6034   ATTENTION!! The quality of the GPS data from the rover or nearby
 6034   CORS sites was too noisy and below minimum standards to attain a
 6034   meaningful solution. To avoid this unexpected inconvenience the
 6034   user may want to re-observe at a different hour of the day and for
 6034   a longer period of time.

 6009   The OPUS-RS solution for the position of the rover has
 6009   failed to converge after 5 iterations. This could be due to
 6009   especially noisy data (among other reasons). If you really need
 6009   a position for this station, you might try another data set.
