Well, it's been saved from the dumpster, at least for now. But, I kind of don't care much about the dish itself - it's probably a bit big /heavy for my Az/El rotor setup, though it's hard to tell with the huge steel support mount still attached. I nearly wrenched my back out carrying it over to my side yard this morning. (I think the Advil is wearing off... oow)
But, back to the pre-amp and other electronics pieces... I found a reference to the Hughes DirecWay (not wav) service on the Web. Looks like the stuff runs in the Ku Band (11-14.5 ghz, according to Wikipedia), and has a 0.5-2 watt transmitter, depending on model. Sounds like it's possibly a good bit out of band for P3E needs, and I'm not much good with microwave hacking. Am I better off taking another two pills and putting it back on the pile, or is there a reasonable chance that I can do some simple (think "Drake") modifications to get it to work?
