If they have a truly competent RF shop, and know how to use the FCC database (not some manufacturer website) to look at the nearby TV transmitters, I'd give it about an 85% to 90% chance of being problem free without an RF site survey and without a somewhat knowledgeable RF tech to set up the system and confirm performance. |

A local performing arts school a family member attends is putting on a show where they want to use 18 wireless microphones. They have contacted 2 rental companies more than 300 miles away to supply said wireless systems. I am a little worried which maybe I shouldn't be but, my experiences with many wireless channels has not been good. What are the chances of a rental company(in Austin Texas or Dallas, Texas) setting the frequencies on 18 units to not only work together but work in the civic auditorium in Harlingen, Texas without issues? |

Most UHF systems of professional caliber have "auto-tuning" features; turn them on, tell them to look for an open channel and they'll perform their own UHF sweep. Then you just leave that one on, fire up the next one and tell it to find an open channel. Rinse and repeat for the rest of em. |

Not quite, If the units are all in the same frequency range and are not networked so they can communicate with a computer then you need to scan with one unit, choose a frequency group that that unit has found to have enough available frequencies and then tune the others manually or allow scanning but be certain to use the same channel group when you set your frequencies. Also, it is important that you set your squelch levels the same from unit to unit or one unit may see available frequencies that another unit does not. His, Lee Buckalew Pro Sound Advice, Inc. |

Henry, would you care to expound at all about "some manufacturer website"? You don't have to name any names, but I'd like to hear what kind of problems you've experienced (or heard of) when using the manufacturer's recommendations. |
