Question for the Optima owners: I was reading through the owner's manual and on Page 9 it states: "The Mosfet PA devices used in the Optima will automatically decrease in power if they experience excessive heat build up." 1. Do any of you run this radio mobile? If so how does it handle heat? ANyone know the temp at which the output power is reduced? I'm curious if the radio would transmit 100% power in a truck cab that's been parked in La. summer heat (100 F in the shade, hot as hell inside the truck cab) Thanks for any info.
