Mission Planner-3DR radio Failing - How To?

Hi, In my current setup i use Reach gps as primary gps. From the original GPS unit (the one that came with pixhawk i use only the compass)

One of the problems with Reach is that the reported ground course (heading) is wrong. That means that your GPS heading and your compass heading will not match. I’m not sure if the EKF will be happy with that. The good news is that I fixed that, the bad news is that your are going to have to recompile the Reach source code in order to integrate the fix into your system.

Fix ground course calculation

and

Fix make install paths

I’m interested in your flight findings with reach as main and only GPS, please post them.

One downside is that you need 2 radio modules if you want to have telemetry and base corrections for the gps.

I do not get this one, you can get both shared telemetry and injection with a single pair of 3DR radios. Are you saying that you need two pairs for this ??? Then you probably did not configured your system right.
