F--K ME that RFI setting is dodgy!! It's so inconsistent! I can only get it working occasionally now! Reboots, power cycles, resetting it to 1; none of these seem to be working now. I can't get it working properly on ANY of the RFI settings now!! It's SO FRUSTRATING!!!
An alternative explanation is that the RFI setting isn't doing anything and that some other factor is coming into play here, but TBH, since I've seen multiple 8+hr runs with RFI on where I get 0.5 CRCPM or less, where previously I'd been consistently getting 8+ for weeks on end with RFI off, I'm reluctant to settle on this conclusion.
Is anyone else willing to do some testing with RFI to confirm if we're all hallucinating or not? Stevehodge - your testing was interesting, but I think most of your changes were due to SNRM increases vs any difference with RFI.
