1000.4 to 1000.2 Modification

[ivanme]

I did the 1000.4 dish to 1000.2 dish mod exactly as it says here in the stickies, im getting a lock on 119W where the 129W LNB is supposed to be, which is the far left lnb if you were standing behind the dish, TP 12501 S&Q is 74% and 69%. 110 W is locking on at approx. the same S&Q and on the correct LNB,far right standing behind dish. The middle LNB, which is supposed to be 119W, only seems to lock onto 110W. I have made adjustments in elevation and azumith and cannot get S&Q any stronger and there are no obstuctions or interference. Can this be due to LNB not being grounded? Im using an nfusion nova to find sat signal. Seems like 110W is much easier to lock onto than 119W. Im not sure if im reading the elevation correctly, im using the elevation indicater line under the nut instead of above the nut as would be used on a dish 500, its seems to be the only way I can get a signal locked whatsoever. ANy advise greatly appreciated.

Use the marking on the elevation scale above the side nut. Connect your cable to the port 1 on the lnb (farthest left of lnb in) and use tp freq 12370 on 119 to peak the dish. If your skew is set correctly the 110 and 129 sats should fall into place.

Thnx BKR im gonna try that out as soon as I get home and I'll be sure to post my results.

You also could be having DC power issues with that triple head LNB you are using, most FTA receivers only put out 500 mA of DC current, this is not enough to run the D1000.2 LNB it needs at least 650 mA of DC current to run right.

Symptoms of being starved for current are switching problems or missing TP's or satellites.

Ways to fix this are, 1, use an old Dish 301 receiver to power the LNB on its port #1, 2, use a DPP44 switch DC power inserter on port #1 of the LNB BY ITS SELF, 3, use a DPP44 switch with power inserter to run everything, if you use this configuration the power inserter has to go to the switch receiver #1 port by its self on its own coax.

Also the coax your using can affect the power to this LNB, too long a run of the cheap copper plated steel cored RG-6 will cause a big voltage drop and you will have problems, recommended coax for long runs over 50 feet is RG-6 quad with a pure copper center conductor.

Well im still having trouble over here, im using 3 legacy single LNB's so that rules out short power supply. Is it possible the LNB holder arm is to long now that the modification has been done to it. Also I cannot get any signal lock using the marking on elevation scale above side nut, only below side nut as I mentioned in previous reply to this thread.

The focal distance from the center of the dish to the face of the lnb is @ 18.5". You are using the center lnb 119 and the correct tp freq 12370 on the receiver and you set your elevation and skew based upon some tables. Eventually you will hit 119w sat.

OK BKR I just measured distance from dish to face of LNB and it's 28" I'll shorten it back down to 18.5" and see if that works

The "w" bracket even though is mounted on the smaller rectangular tubing of the older dish, slip it down all the way until it touches the larger rectangular tubing of the 1000.4 arm, the focal distance is closer to 18-3/8".

Finally, success, I did like bkr said to and with alot of patience I now have all three sats locked on. At first It seemed like 110W pop up banner was showing up locked on 119W diseque port but once I exited out and opened antenna settings screen back up the proper pop up banner showed a locked signal on its respective sats, I also have to give a thanks out to another thread where I read about using aluminum foil to block off the other two lnb's while trying to find 119W. May not need to but hey it worked for me. Now time to get this Ilink 9500 up and running. thnx again bkr and Terryl

Great news, glad to see you got it going...............................Now remember on how you did it as there is a test at the end of this semester.......:trampoline::teeter:
