Hi all. Name here is Art and I'm brand spankin' new to the forum so I'm sure I'll do something silly in my learning. I have had major issues with converter noise in a trailer but I was able to solve mine with some basic troubleshooting. The new power converter I put in an old (new to us) trailer turned out to not be FCC Class B certified. The certification means it should not emanate any rf noise, however, mine did. I emailed the manufacturer and asked why it wasn't certified and they pretty much blew me off. I then removed the converter and installed a 40 amp ham radio supply and ran it through a battery isolator. The isolator was necessary as the meter lights and fan would continue to operate as long as there was 12 volts on the output terminals even with the trailer unplugged. The isolator prevented this.

Hope this helps as I know the frustration of the hash from a power converter. Especially when I found my problem, Field Day weekend.
