Thanks for the explain Mark. Of course, there would have to be an NTS station available 24/7 somewhere in the country, (emergencies don't happen on a schedule) like, ECARS on 7.255mhz, which i believe is daily.
I'm very surprised the fed's would be interested in SSTV :?: you would think they must have the latest technology at their fingertips :?: :?:
I also live very close to a nuke plant (Indian Point), just one of the many reasons I'm moving next spring.

A national network is not needed, but it would be beneficial. Certainly you can use any frequency to get traffic in and out, but having NTS would make things easier.
I live near two nuke plants, one of which is TMI (Three Mile Island). The EC guys do regular drills, and recently the FEMA people (or whomever; I don't know their real title...but they're gov...) has expressed an interest in SSTV over our 2M repeater. Slow as molassis, but it gets the job done. Now, let's say there was a need to get an image out of my "region" (which you can define as you want). I wouldn't have a clue as to what frequency to squirt out some SSTV. It would be hit and miss. However, if I knew where NTS was operating (voice), I suspect they could relay for me, and get it to the destination quicker than Joe Ham that I stumble across.
