@eli Okay, since he's in Denver I think his best bet is to join the RMRL club, a Denver club with about 250 members. I'm sure there will be someone in such a large club who can help him with APRS. The club is online here. It's only $20/yr to join (see the Membership tab). They have a weekly meeting on the air on Monday night at 8:30 pm. The Membership tab gives the frequencies of the repeaters & the tone he will need to access the repeaters. If he checks in to that net and explains that he needs APRS help, I bet someone will be able to tell him one or more hams who can help him out. They have a club roster with contact information for all the members. Let me know if that works out for him. If not, we'll find some other approach for him to try.
