[WriteLog] Message breakdown

Thanks Jon and other contributors. It doesn't sound like it is specifically a WL issue so I won't carry on the debate here. I have some microHAM boxes that I used with the previous rig (756 ProIII) and never had the problem with that setup so will consider using them if I can't find another solution.
