Having the engine monitor operational during start is 'nice' and
seems like a must, but for me the brownout problem was for the rest
of the EFIS function - flight plans and such - along with the engine
monitor display. I had this brownout problem with a dual alternator
-dual batt Z-14 on my RV10.

Well, it's not a 'radio' but the EFIS. I don't care if the 'radio' gracefully
recovers or not from a brownout at start.
Too specific on my part . . . sorry. It's an
electro-whizzy. In particular, one that stores
data in non-volatile memory and/or takes a
non-trivial interval to wake-up after power-ON.
In my case, little/no risk if devices are allowed to fully boot or
re-boot. Having them re-boot during the boot process can make them
sick. I'm not worried about the oil pressure either.
Not sure what you mean by 'sick' . . . other
than loss of data that could/should be in
flash as opposed to ram.

Yes, part of my 'kitchen sink' of electro whizzies. I knew what you
meant but maybe would should stick to proper technical terms like
'whizzy' and 'kitchen sink' going forward.

I can't draw a straight line between my need to return a unit to the
manufacturer for ''adjustments' a few years ago and my repeated re-boots
during the boot process. A manufacturer rep suggested that it could
have caused the problem that required the return but I'm not sure that's
accurate.

Understand . . . but color me skeptical. Design
deficiencies not withstanding "booting
up" is not a stressful activity. I am reminded
of an oft proffered diagnosis by the warranty
service tech praying over a slightly smoked
radio, "I guess a spike got it."
