I guess that is why I mentioned something about doing it competently.
The FCC so seriously winged the methods usable by hams as to render them effectively useless. A nice direct sequence spread spectrum system with a couple of MHz spread would be well below the background noise of any narrow band receiver. Sure, you could find it with a wide band detector if you were close by, but how would you know that you weren't looking at some other anomaly, like a bad insulator, or trash coming off of fluorescent lamps? Done correctly, you could run spread spectrum just about anywhere you wanted to, and remain undetected. Using direct sequence, you would be so low in power density that it could easily be argued that you were operating within the constraints of a part 15 device's leakage. -Chuck Harris Bob Camp wrote:
Hi Remember that this started out running a sequence that was 127 hops long. With something that short, it's pretty likely you will be rude to somebody. Even if you are running a massive hop rate, I can likely walk around and track you down within the average neighborhood. A diode detector behind a bandpass filter and a small-ish directional antenna is about all I'd try to use. I suspect it would also work with one of the power detector chips. Range wise, a lot would depend on just how good your local cable company is at keeping their stuff running right. I'm not really sure the chip would add a lot of range in a normal setting. Bob
