2old, you rule! Your posts are among the most informative I've come across on the sat boards in a long time. Thanks!
Of the links above, one still works (http://redrival.com/madtrax2) and I've downloaded a log from there. Now what do I do with it? The site has a program I cannot get working, any suggestions for other software that can use these logs? What info is needed to extract HMKs from it?
