I'm looking at DC-DC converters, as I'd like to supply my HF radio equipment with a clean source of 14.2V to minimize transmit IMD. My power is via LiFePO 4 batteries, and to maximize efficiency, I am thinking about using a 24V configuration with a Orion 24/12-25 to drop this to 14.2V. Maximum current demand is 23A @ 13.8V.
How RF noisy is the 24/12-25 in the 0-30MHz range? The setup will be relatively close to the radio and antenna, so minimal EMI is ideal, at least in the spectrum in question. I've heard that Victron is generally quite good in this realm, but hadn't found any reviews/data about these DC - DC units.
