IBM collected a lot of hams. Back in the days when I was in DC they
were already migrating to digital, hooking ASR33s (teletype) to their
ham gear. Some still worked 2 meter radio telephone but not that much.
The guy from Ft Myers who retired in Tennessee says they have a pretty
active ham group there but they are connecting up PCs.
I guess ham has become just an RF modem.

Digital comms is sort of on the cutting edge of ham technology these
days although it goes back more than 15 years at this point. There is
a device called a Pactor modem which acts as a combination modem and
packet encoder. It attaches to either a ham rig or commercial marine
tranciever, and allows error free transmission at speeds up to 4800
baud under good conditions. It's fairly sophisticated in its
operation, automatically adjusting speed and re-transmissions based on
radio conditions and error rates. I use it when we are cruising in
the boondocks for EMAIL, weather, stock market quotes, etc.
