Hey Wim,
Glad to hear that the grounding solution was in fact the easiest fix, for now.
Yeah, extra wiring is ugly, but sometimes it’s necessary to make things work
out.

Thanks everyone for your suggestions. Chris was right: I needed to ground
my recorder. The buzz stopped as soon as I wired the headphone jack to a
gas pipe in my house. While my Marantz PMD661 is a nice recorder, it
apparently is not designed to be powered by AC while getting its signal
from
Wim, I don’t know if your Marantz accepts external USB power. If it does you
could buy a high capacity powerbank (say, 2mAh or more), connecting it with
a USB cable, and that would probably solve both problems: autonomy and noise.

I am guessing you are using a power supply from your junk box, not one that
came with the recorder, and that is a switcher (most of them are now) and
it's a cheap (noisy) one. Ham radio people address by either finding a
better switcher or by using a linear supply.
Batteries don't care about

Is the Marantz powered with a two prong AC to DC power supply, or is it also
grounded? It might be worth trying to ground the Marantz recorder housing to
house ground. I had a similar problem with a home stereo system and the 21c
OldBird flowerpot mic. Grounded the stereo to house ground and
