Bob, while the number of FT-51s and TH-78s might outnumber THD7s, I think
the question that needs to be asked is are the owners interested in such
a service? Instead of focusing on older HTs that people may or may not
have. Has anyone ever looked at a APRS -> POCSAG[1] Gateway?

Older, working pagers are a dime a dozen on the used market and there are
some people who have refitted them to work on Amateur bands[2]. With the
fact that there (quite literally) buckets full of working pagers at
HamFests, why not have a "messagegate" that takes APRS messages to
stations and translates them to a message destined for a POCSAG
compatible pager. There were certain KAM TNCs that could encode POCSAG
natively

Comments? Laughter? Rotten tomatoes? :)
