Re: Waris (CDM1250): Limit Tx power on a Personality basis?

I don't know that you could do it with tuner anyway, in the CDMs the tuner doesn't adjust the output power, it calibrates the power sensor. The radio then adjusts the power so the wattage it senses matches the value set in the codeplug. Even if you can trick it, it's going to take a lot of fiddling ...
