I think we've strayed from my main point, which was that there is no reasonably easy way to power one of these so it will recharge the battery or to power a docking station by using a run-of-the-mill linear power supply.
For practical purposes, I really don't care what inside the supply is causing the RFI, not do I want to debate the relative merits of whether or not the DC line has a ferrite on it (which could be of a completely inappropriate composition on these Chinese-made knock-offs anyway).
I've found a supply that, after wrapping the power cord around a large ferrite, generates noise at a low enough level that I can hear most stronger stations. I've moved the 6m rig away from the computer. It's the solution I have to use, but a much better solution would have been to be able to use a nice, stout Lambda linear supply. My bone of contention is that you can't disable the "feature" from the setup or otherwise in the software.
