Hi all,
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?

Greg- They seem to be an off center feed antenna, similar to the old primestar dish of which I have been successfully using for several years. If it's free you can't beat the price. 73 Bob W7LRD

Hi Art,
The DirectWav is an Internet link - data, not TV - but good point about LO stability being an unknown.
But, my base question was whether any of the pieces can be used, and it sounds like it's worth saving. Thanks!

Greg, These dishes are used on 10 GHz and lower frequencies. Designed to operate in Ku Band ~12 GHz they will give ~30 dBof gain. The LNB and feed can be used , at least the LNA section. As the intended use is television the LO is not stable enough for Amateur Satellite work.

Hi folks,
My neighbor appears to be tossing their Hughes "DirecWav" satellite internet dish and associated dish-mounted electronics. By any stroke of luck, is this stuff reasonably convertable for use with any of the the proposed P3E up or downlinks? I have no idea what frequency it runs. It appears to have both transmit and receive capabilities (based on the warnings posted). There are no model numbers tha t I can find on the electronics.
I've got my AO-40 S-band receive setup, but nothing for the higher bands.
Thanks,
