What frustrates me to no end is calling to report something and clearly and succinctly giving all of the pertinent information, in a clear yet quick manner, and then they say "OK so you're reporting an accident? What's the location?" Gee...already answered! They could have people on the way but they want to ask 20 questions that were just answered. Extremely frustrating. Just listen lol
A couple of answers for you:
1. CAD,
Computer Aided Dispatch. Dispatchers are sitting at a computer and are having to type information in to specific fields. The caller doesn't know what order the fields are in, and most dispatchers are being bombarded by a huge amount of input. Letting the dispatcher -ask- you the questions in the order they need them really helps the process a whole lot. When they answer the phone and say "911, what is your emergency?", you should be answering with no more than about 4 words. Anything else is just information overload. This is what I meant about the 45 second monologue. Short answers to the specific questions you are asked.
2. The dispatcher you are talking to on the phone isn't necessarily the one that is on the radio passing the information.
Often the "call takers" are typing the info into a computer and then route it to the appropriate dispatcher. In big centers they may have radio dispatchers assigned to the different services/districts/agencies/beats, etc. That means the person you talk to isn't going to be able to recite all that over the radio.
3. Prioritization.
This is the -BIG- issue. When someone calls 911 (or pipes up on a public safety radio channel they shouldn't be on) they are assuming that their specific emergency is tip-top priority for everyone involved. Often, it isn't. I've sat in our 911 center and listed to this happen more than a few times. The dispatchers job is to prioritize the incoming calls and get the right resources to the right places as quickly and safely as possible.
This is the issue I have with amateur radio operators, GMRS operators, CB'er's, etc. all assuming that they need special treatment from the public safety field. The assumption that a 35 question multiple choice test or a paper license somehow makes an individual suddenly more knowledgeable than everyone else and able to assign priorities in situations where they have a little tiny slice of the picture is dangerous.
What would be an -awesome- solution is that if the Amateur/GMRS/CB community took on this task themselves. Amateurs could monitor 146.52 or high-site repeaters. GMRS operators could monitor 462.675, CB'ers could monitor channel 9. Heck, one guy with an amateur license and a GMRS license could do all this themselves. It would be a great club project, or a job for retired amateurs.
Expecting the already overloaded, stressed, overwhelmed dispatchers to take on yet another role is expecting quite a bit. They are already having to take on SMS/Text Messages, which isn't fun.
This is why I recommended a PLB as a solution. It's a proven tool and it's affordable. It doesn't cost anymore than a new mobile radio. It follows the protocols that already exist, and it doesn't require building out any more infrastructure.
