Yup. Look at the channel busy statistics. YOur channel isn't busy at all.

Anything bursty, wide or narrow band, will cause issues.

Ambient/Automatic Noise Immunity. There's some code which adjusts some
PHY parameters to do with signal sizing and offset; however I may have
(more) broken it.
I need to sit down and add some further debugging and write an
inspection tool or two to figure out exactly what's going on.
