Why would 5W at exactly 9V, for the 9V version be ok, but 5W at exactly 13V, for the 12V version, be dangerous? FWIW, I’ve ran my QMX off a LiFePO4, transmitting with as high as 13.8V, but mostly in the 13.2-13.3V range, with no problems. But to be fair, I’m using a manual tuner. ?But again, it borderline feels like what I’m reading, on a near daily basis, is running more than 4W at 12V is a sin.?
