I've been searching the forum and found a couple of posts that talk of this PSU (or similar). One reported seeing wide band noise but then no further information, others seemed to use with no problem, but of course if it is frequency / load dependent then it may be present, they just haven't seen it.
A couple of threads had people with access to emission testing equipment and said they might test these units, but nothing ever appeared with any results that I can find.
It would be useful to get a definitive answer as these psu modules are physically ideal for box integration.
I would have thought that an eventual natural PAW progression might be to offer a fully packaged, plug and play box for sale and that a working integrated PSU would be needed  for such an item. I suspect that such a box will be needed to provoke mass appeal of PAW to "non tech" pilots.
Thanks Paul for the thread link, this was one I also had found.

Here's another thread with RF interference issues. It has a couple of recommendations but in cigarette lighter format.

Though I see one's not available any more, but a single USB version is. Note that it's 12V only, not suitable for 24V.

By the way, anyone reading this almost in real time, the Anker car USB thing is currently on a lightning deal for the next 2 and a half hours!

Aha! I found the other post about the noise on the CPT and about another recommendation.

http://forum.pilotaware.com/index.php/topic,745.msg9675.html#msg9675

The other recommendation was this:

But again 12V only.
