Dear Friends, By the way, on the Mods DK site, it tells me that all I have to do is find W163[AT] below IC1 in the CPU compartment and clip it. BUT... mine has no jumper installed whatsoever in these circuit board holes. See the article here: http://www.mods.dk/view.php?ArticleId=3020 Thanks in advance!! Steve, XE1UFO a.k.a. KA5SUT
