Hi - a few questions:

What's the frequency of this interference - I can't read the timescale at the top of your screen image? Ignoring the interference, do the two built-in mics pick up sound equally when the DR-1 is pointed at a central sound source? Is the interference independent of whether the DR-1 is running from internal batteries or from the power adaptor? Do you get the same effect on the L channel of external stereo sources fed in via the 1/8" line input?

the wavelength is about .026 seconds. Both mic's pick up sound equally. I am running the DR-1 on battery power, i do not have an ac adapter. The static is present on the L channel while fed through the 1/8" line input. Another thing is that while I am recording, I can hear the sound through the headphones as soon as I hit the record button. I have recorded without headphones plugged in and the static is still present.
