I've decided to bite the bullet and buy new ones Depending on your needs, I think you can get a new CAP version for as little as $2000. More likely though you will more features, so figure more money. That said, I still think it is worth it. Current EAS boxes are only capable of storing and relaying a two minute message. Right now, the National Weather Service seems to ignore that limitation all the time and frequently gets cut off, just when they are getting to the important part. As I understand it, CAP has no such time limitation. If you use a converter, and the message is over 2 minutes, I suspect it will re-launch more duck-farts and start a new alert on your old EAS machine. That will get real old, real fast
Then there is the printer.... The two EAS boxes I look after have built in printers. While that seems like a good idea, in reality, they are a service nightmare. If you let them run out of paper (Oh, that's never happened...) they are a bitch to thread, especially when the box keeps going off during a round of severe storms. Of course, that's when they unexpectedly spew out 30 yards of paper and all of a sudden, you have to reload them. Did I mention the ribbon? It’s also a pain in the posterior to change.... It's almost worth the extra money to not have to deal with that.
All the new units can store your logs electronically, which you can off-load onto a computer where you can burn a CD, store them on your hard drive, print a paper log or whatever. I'm led to believe that the FCC will accept an electronic log as long as it contains a digital signature showing that you reviewed them. They also have multiple USB ports and Ethernet connections (some more than one) so connecting a printer or to a network should be easy.
For the extra money, I think you get enough value to justify the cost. It will also help you keep up with the next edict from FEMA, the FCC, your state or some new and unforeseen governmental force. You know that they will keep tweaking on this system every time some government agency thinks of a new way to defy the laws of physics. CAP and EAS is not going away, and resistance on your part is futile. All of the new boxes I've seen are software upgradable by just downloading the new parameters. Hopefully, that will be a relatively simple process. We'll see.
Let’s also think about how old your current box is. One of mine is about 15 years old. The other is about ten years old. How much longer should I expect them to work? Not long, I suspect. Putting a new converter on a 15 year old EAS box is a bit like the "hundred dollar saddle on a ten dollar horse."
Now the big question is which one? Digital Alert Systems or Sage?
