I imagine that due to the KPA1500's size it requires a higher volume of air than a large amplifier would. Its small size and weight make it appealing. The Acom 2000 has a control box that is separate from the amp so you really never hear the amp run. I am wondering it something similar can be done

Andy, I have seen this too.  My remote tuner will sometimes quit with SWR in the 1.4 : 1 range.  Sometimes it causes a KPA500 SWR Fault and sometimes not.  My GUESS is that it depends on whether the impedance is <50 ohms or >50 ohms.  The SWR does not tell you which. Michael Blake
