Well, since hams use satellites also for operating, maybe that will help keep it going...?
"I am not a HAM operator but it will still be around because it is a proven way to communicate that does not use VOIP or GPS."
In 50 years we will be so "wired" by glass, HAM will be a dead tech. HAM is already dying. Look at the increase of the average age of the HAM radio operators. The always gets thru willl be a thing of the past as well. Satcom and glass will ensure this far better than a CW rig.
