>From what I know Zcomax use their own amplifier design and its output
power cannot be changed via standard Manual TxPwr setting. Also it does
not report current power correctly as well.

>From what I remember when you change the power manually the driver starts
to report the power you have set instead of getting it from the card which
would explain why iwconfig says that you have 23db power.
