Interesting. I noticed some odd things about the 788T which might relate to what you mentioned: 1.) The first night of testing, I had the unit running off of battery power, but noticed a spike in the level meters when I attached my laptop power cord to my laptop. Strange! 2.) Still in battery mode, I also noticed level-meter spikes when I touched the headphone plug to the headphone jack on the 788T. It definitely seemed as though something funny was going on electrically, but I don't know enough to comment. > A (possible) cheap cure worth trying on unbalanced lines is the clip on > Ferrite sleeves often found on computer cables. > > http://jaycar.com.au/productView.asp?ID=LF1294&keywords=LF-1294&form=KEYWORD > > Even better if you can take a turn round the Ferrite.

I'll experiment with more things in the future - yesterday's method of skipping the extension cable seemed to work great in the RFI-heavy Times Square area, luckily.
