Hmm, does anyone know where to find a 1690MHz LNA? I'd like to experiment with EMWIN some.

I got some silicone tape from Radio Shack, which bonds very well to itself. Wrap up your connections with this (wrapping in the direction that the connector twists on), and then wrap electrical tape over it. That should keep it fairly weatherproof.

I'd like to enter to win a Fortec Mercury II. It would be nifty to have multiple receivers and pit the Fortec's blind scan against my Coolsat 5000 :)

I spotted one in the back of a pickup truck at the grocery store. I managed to catch the driver as he was about to leave and asked if he was going to use it. Turns out it was on its way to the dump :) It looks like it just came off someone's roof, it even still has the LNB!

Wow. That's quite a beast of a machine! If you like Dance Dance Revolution, check out StepMania, it will run very well on a computer with those specs. ;)

Huh. Mini-ITX board, wonder what brand they use...also wonder what tuner card they're using. Aha! This appears to be the mainboard: http://www.logicsupply.com/product_info.php/cPath/78_76/products_id/487 Still curious about the tuner card :) Scott, think you can do some info digging? :)...

Oooooooh....*very* nice. I may have to rethink my decision to go with a 90cm dish, a 1.2m sounds very tempting now.

Is it aimed to true south or magnetic south? For you, your true south is 175 degrees magnetic. Also try slowly sweeping it back and forth across a small arc, adjust the elevation, and sweep again.

Hm. Looks like a bunch of ad fodder with no actual content. Spam?

Hm, I've wondered on the feedhorns with the servo, do the tuners adjust the servo for appropriate skew on each sattelite, or do they just crank it 45 degrees either direction? Or does the movement of the dish on the polar mount take care of skew?

You'll need some way of controlling the actuator. BUD actuators work on a 36-volt drive with pulsed feedback to tell the dish mover how far the actuator has moved, the Twinhan card is designed for 12-volt low-current motors that talk DiSEqC. A V-Box or V-Box II to translate should work.

My guess is that the cable is probably all junk unless the ends are well-sealed, braided shielding has a wonderful way of wicking water faaaaaaaar into a piece of coax.

Probably for credit card transactions... http://en.wikipedia.org/wiki/VSAT

Downside: They take forever to take down/put up, thanks to the several hundred metal clips that hold the mesh to the ribs.

I'm not sure I understand. Somehow the RF is supposed to pass through the sphere, but then reflect off the inside to focus on the LNB?

Huh. How strange. Wonder if that'll change with any future software releases (as well as the scans-before-the-motor-has-finished-moving bug).

Also check out the Radio Laboratory Handbook, might be some good stuff in there: http://wireless.ictp.trieste.it/handbook/index.html

Wow, you've got great quality on 11805. I'm in California, 76cm dish, I get about 75% quality max on the research channel with my Coolsat 5000. Ok, so the short answer is I didn't screw something up with my setup...that makes me happy :) Now I just need to figure out what's keeping the...

Any linear LNBF should do it, either a standard or a universal.

Yep, cut the receiver's power while I was mucking about with the cables. I even waterproofed the connectors with self-sealing silicone tape and electrical tape.

Yesterday I added a DMSI 4-way DiSEqC switch and an 18" dish to my setup (trying to get the music on 119W). I think I've got it all set up correctly, G10R still mostly works on my fixed dish with an Invacom universal LNB, but I'm getting no signal from 11720V (where I used to get around 60-65%...

Heh...time to stick a pink flamingo to the end of the feedhorn cover, just for fun :)

There's a bunch of info on making motorized az-el dish mounts here: http://www.ultimatecharger.com/dish.html
