Our two cats didn't seem to be bothered by the transformer or coil noise at all. They were simply inspecting the hardware with due curiosity, and one of them even took a nap in the vicinity. And I am sure they do hear well, proven by their unambiguous reaction to certain little noises coming from the kitchen Marcus, maybe it's because they practiced listening to DHO38 for so long, that a 9kHz whine doesn't annoy them now :) they hear up to 64kHz according to this: http://www.lsu.edu/deafness/HearingRange.html VY 73 Jacek / SQ5BPF |
