Tlog to look at Radio Link

Hi, I am having issues with my 3DR radio dropping in and out. I have other problems too but I want to try and get this sorted first. I have my radio well away from other electrical components. Here is my log. If you would like me to chart any other values I can do that.

Log file:

Any suggestion appreciated,
Ben

I have RFD900 pair now so no longer an issue.
