If you're getting true brown outs then its a power problem not a radio problem and you will get that with any radio system if you don't provide adaquate power input.
True. But not all radios have the same threshold or reaction to a loss of voltage. If a low voltage "brown out" can be induced by normal flight operations versus the low voltage being due to an actual battery problem (loss of charge, depletion, pack damage), then those are fundamentally different situations and to say that all radios are susceptible to brown outs is not particularly meaningful. In addition, some radios are also capable of warning that the voltage is getting dangerously low before it actually causes a loss of control.
