The witty response Bob is amateurs would do a better job (radio amateurs of course). Some people love the Q900, especially V4, but I am skeptical of the longevity of the unit. I am now using mine outdoors portable only and at half power if on FT8 into an amplifier. It still gets warm though. It should "be cool" to have two fans but it is not cool in the literal sense. I think, as you say Bob, the design is not optimum.
