It does, in fact. It has a 3.6V NiMh, which I suspect is a much
harder (lower impedance) voltage source than the 280's 1.5V alkaline.
But it could just as well be a shielding or power supply filtering
deficiency. We nature recordists are as demanding as classical music
recordists.

Level MIC L 12. Just barely audible fitzing mixed with the mic noise.
Quiet desert scene. Later takes (wind died down) at MIC L 17 had no
problem, so it wasn't a problem of coupling to the mic preamp (if
that were the case, it would get worse when gain was raised) but
probably in the A/D converter.
