This would slow down the tuning process though. Instead: How's the chance the firmware is being fixed not to crash but to gracefully ignore data it can't handle? Some configurable plausibility checks on header data would certainly do (This would obviously also help on the subject off ARM crashes upon loss of signal or garbage received)
