As suggested by several here on the AMSAT mailing list, I removed the USB adapter in my LVB Tracker and inserted a MAX232 chip into the appropriate socket. I am using a Utek UT-880 USB to serial adapter with a Panasonic Toughbook CF-29 running XP Professional. It appears that everything is working now with no lockup failures. Before these changes, I simply could not track a complete satellite pass without the program stopping. I have been tracking the moon for hours with no problems noted. Now to test this arrangement with my Mac! Before making this change, MacDoppler worked perfectly. I hope it will continue. My next step is to fine tune the control of my IC-910 using SATPC32.

As they say, "I was all dressed up with no place to go" late last night on FO-29. My LVB Tracker was working great with SATPC32, I had my IC-910 running about 20 watts, I could hear myself 59 on the downlink, there simply was no one on. Oh well, there will be many more orbits in which to play.
