Cant reduce TX power??

I don’t know if this behavior is specific to SXT lites, or specific to NV2 (both of which I have just started using), or something else, but my newer units are not obeying the TX power setting like my older units do. Here’s an example:

Same thing happens with “card rates.” The router just ignores any attempt at power reduction. I know it’s not lying to me, because the signal levels from the unit to the tower never vary.

I’m running 5.25.

Why is this happening?

On SXT lite and new chipset - works only Regulatory domain and ALL RATES FIXED.

Card rates don´t work
