Two words: 'water goods'. At least that's what they are called in HK.
Amplifying handhelds to 50 and 100watts in the VHF range, certainly in
a consumer product, is just not done. And the other markings, because
they cover the air band *has* to be wrong.

At least this is how my western mind would keep from being betrayed :)

I would wager reasonable money if you bench tested this radio it would
neither xmit in that range or power
