Re: CDM1250 Changing mic from front to rear

Since one doesn't normally plug a mike into the Acc Conn, they don't provide power on the TX Audio input for that

I'm pretty sure they do have the bias on the Acc connector.

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 ...
