I didn't see more than the pics on line. Is there more to look at? I couldn't see the heat sink at all, since it seems to be in a box with a fan at the end of it. I'm kind of surprised they could get away with only one fan, but maybe the 1 kW rating is PEP for SSB only, which is low duty cycle...couldn't really tell what its key-down (or RTTY) rating was. Pretty packaging job, though!
