[TX-Power on newer FW]

Now what we didn't know at the time is that the actual HARDWARE is set to it's max TX power (or the legal max anyway).

I don't have any numbers for what the actual power output of the two cards is, but I can tell you that the software readout is possibly plain wrong.

Seeing as the hardware is locked though, on the newer firmwares it stays at the level it reports.

I'm still a bit confused. So.... You are telling us that that there are a few options like:

- AR9331 radio is locked and nobody really know this because it gives fake readouts

- AR9331 is operating at >18dBm power after changing REG but it gives fake readouts and nobody know its "true" tx-power

- AR9331 cannot go >18dbm because factory limit

Which of these is closest to truth? Because in every YT video of MKV there are "two powerful unlocked radios" and now we have one powerful unlocked radio and one 10x weaker...
