True interoperability isn't just about the equipment. Any clown can go out and buy a bunch of radios. Where the issue lies is in user training. A lot of public safety people don't have a clue how radios work. It's just another appliance. They know how to turn it on, push the button and speak. Spending millions on new radios won't change this.
Officers are required to re-qualify on their skills frequently. I've never heard of anyone being required to qualify to use a radio. This is a big issue. User training is often ignored, or not given anywhere near enough attention. The push is to buy the radios, get them programmed, and get them in the hands of the users. Attempts are made to "match" the functions of the older radios so users don't have to learn anything new. While this sounds like a really good idea, it usually isn't. I've done this before and it does make it easy in the beginning. They get their new radios, as long as it looks, performs and sounds like the old one, they are happy. If you change the color, size, brand, or way the channels are organized or the buttons are set up, there will be a riot. Some radio programming goes back well into the 70's when hand held radios made the scene in big numbers. A lot of agencies are still using "Color" channels, going back to the time when the radios only had a few channels and their was no display, only colored channel selector buttons. It works to a certain extent, but it has resulted in users who have no idea how to use the radios they are carrying.
This article exemplifies that. They gave DHS members brand new radios with new channels and new functions all with good intentions. The result isn't the radio failed, it was the lack of training that failed.
Easy to fix, but it will be easier to blame someone else.
