How to start with new X2 Receiver?

"There seems to be a device coming out next month that makes that feasible. Hope it is not vaporware."

Not to hijack the thread, but Rick's has had this available for a while. Might be something you're looking for, before the Titanium comes out with their version.

Wen, what are you using to control your polarotor now?

Thanks for the information. I will certainly look into it and see if I can integrate it into my setup. Yes, Titanium was the one I had been waiting for since the polarity was automatically set with the input voltage range. Right now I am still struggling with my BSC621-2D LNBF. Tonight, it scanned 35 channels on G16Ku, then some of them just show no signal. I built my original LNA and down-converter back in 1981 and fortunately, it did not have some of these intermittent problems.

I am using it with a diseqc switch selecting c-band and ku-band labs.

This was my last lnb setup before I moved from California to Texas in 1994, so it is at least 20 years old.

Unfortunately, I could not find the remote control for my old analog receiver, so I temporarily gave up controlling the polarotor and bought the band-stacked version BSC621-2D LNBF. I am still hoping that my old Chaparral Co-rotor II will work better than the BSC621-2D does so far! Wish I could see down to 30W, but so far with a 24 inch actuator, about 50 degrees is as low as I can reach and still get to 139. I can physically see down to 34.5 if I can get the actuator geometry to reach that low and still reach the Western end of the arc.

I've used wide band corotor several times but could never get it to scan in properly, especially polarity. Now that I have a dish dedicated to circular sats, I'm just sticking to lnbfs.

Ha Ha....This is what you needed! This was my original home made 12 ft fiberglass dish with an Alliance AR-44 tv antenna rotator to turn the LNA. Only took 15 seconds to change from horizontal to vertical polarity, but the Chaparral Polarator was a big improvement in speed of operation. The only problem I ever had with the polarotor was that they eventually wear out as they are a mechanical device. Notice that this was before the Chaparral circular concentric feed horns were in use. Wish I knew someone who had used the old type corotor II and the current stacked in line lnbf systems. I also have a DMS BSC421 c-band only LNB, and it seems to work well. I always cut a piece of 1/8 inch teflon sheet to fit diagonally in the LNA/LNB throat for circular polarization.

That's quite an impressive setup for 1981, for that matter it would still be today! Did your dish ever make it in to Coop's Digest. It certainly should have!

Thanks for the kind words. I believe I still have all the old Coop's digests in the barn.

The dish was laid up in 3 sections over a mold of chicken wire and plaster. The reflector was tin foil embedded in the gel coating. It worked as well as any commercial dishes.

I was invited by the local IEEE chapter in San Diego to give a presentation on my system as there were so few in operation at that time. The LNA, Down-converter, and Receiver were also home made. The dish was initially driven by a large ball screw actuator and a motor was then added to it allowing you to steer the antenna with a couple of pushbuttons in the house! Things have changed in this industry and now it is rare to even find anyone that knows much about c-band. In the early days mostly hams and technical guys were at the forefront of satellite technology.

Definitely cutting edge technology for the time. Hope to see and read some more of your posts here...
