    I was just looking at Production Intercoms website, and I came across this new type of wireless system- Half-Duplex. There are one or two disadvantages, but it is cheaper, and if you are only using one or two wireless there are barly any disadvantages. There are also many perks too.... for instance, it does not eat up as many channels as full-duplex systems do. Below is a section I copyed from their website-

    There is a diagram as to how they work at- http://www.beltpack.com/HD903-diagram.pdf

    Cool stuff-


    What do you all think? Has anyone used this?

    An interesting system, but in a school system would it be worth the cost? From some of the prices I have seen just to setup the base station would cost about two grand. Maybe for a production company it would cut down on long cable runs. How much does licencing cost in the States.

    It would be nice but if your venue is small enough you could do it with the walkie-talkies that have that caller selection thing that you can set all your walkies to the same call tone.

    I might put it in a brand new facility or maybe in a multipurpose area eg. gym where you can't leave in permanent cable runs for the coms.

    This isn't anything particularly new. Interfaces to allow a ClearCom system to broadcast via a two-way radio with the call button as the PTT button (as well as to allow the CC system to listen to the radio) have been around for a long time. It's just a small box that plugs right into the external mic/speaker/headset jack of whatever radios you're already using.

    Its not the same two way radios into your existing headset system. Two way radios are simplex. When you combine them together you get half the system full duplex and half simplex all talking together. With this new system the wireless part uses half duplex (hence the name) instead of using simplex. It is not the fullduplex that the traditional wireless headsets use, but this system uses less channels- a real plus if you are using lots of wireless mics. There is more info on the differences between the systems at:
