Thanks for the great review, glad you highlighted the possible design plagiarism (I feel less guilty about owning the 808 since I also have the CC Crane original...). One thing I noticed is you wrote that your radio did not have squelch on Air Band; mine (bought about 18mo ago) actually does.
On my example:
Hardware: squelch available on all bands (including air);
Manual: states squelch only available on air.
A bug on my example is that this sequence leaves the backlight on even with the radio off and keyboard lock activated:
The battery is large but obviously will eventually discharge in storage if you activate the KB lock and expect the light to go out after a delay, something to be aware of when travelling.
Thanks again for sharing the review!
