[App_rpt-users] RTCM voter problem - try 2

Wed Apr 6 14:31:45 UTC 2016

Thanks Jesse,

That was a miss on my part, has been rectified, and didn't solve the
problem.  Still searching for some answers, but getting pretty close to
throwing in the towel on RTCM-based voting.... been at this for 6 months
and still doesn't work and can't seem to find any answers.
