Transmitter / Receiver question
Hello All,
I'm looking at designing a broadcasting system to broadcast a one way signal to a receiver within a large building for speech. I don't want it to be picked up on AM/FM radios and I also need a very inexpensive receiver to pick up that signal only. I have to admit, I know nothing in this field and any information would be greatly appreciated. Darryl |

You probably should look into cuing transmitters, as used for IFB to newscasters and the like. Vega makes a very popular system. You may also be able to use one of the assisted listening systems that work on the 72 MHz band (not the infrared ones). This will be more wideband and may be cheaper. --scott -- "C'est un Nagra.

I'm unsure on the budget for the transmitter - it will cost what it costs -
but I want the receiving unit to be as low cost as possible "Scott Dorsey" wrote in message ...
