Hi Jerry -
I've got two of these rigs and have had no problems thus far, although I haven't yet tried any of the APRS features.
Unlike most ham rigs, the typical items used to set up a memory channel are kind of scattered in different menus. I'll try to help you out, but I'll suggest that we take the conversation off-line.
You can send your questions to my email at AVL307 (at) att (dot) net. Try to be specific as to the issues that you're having.
