I was hoping to avoid the big price tag of a UHF system and got the 88W instead. I wish I hadn't. The initial tests were promising, until I walked further from the reciever, and had some small obsticles between the two units. I began to pickup static that switching between the two channels didn't change. A day or so later, I used it in the field and had the same static problem even when I was well within the suggested range. And again, changing frequencies didn't help at all. Perhaps this is the nature of an FM system vs. a UHF system. And while I saved hundreds of dollars in going with the 88W, I'm afraid to use it most of the time, making this a hundred bucks wasted instead of four hundred saved. Of course it doesn't always do this. And when it works, it is great. It's larger size, compared to the top of the line UHF models, is'nt anything I couldn't live with. But its range and susceptability to interference is a big drawback.
