    Well, I finally managed to get around to testing an old Primestar dish with the 105(and 121) on my 501 receiver using an SW64. With a 35.5" x 26.5" inch dish, I could barely get 70 on the 105. I just switched it to a 39.5" x 29.5" dish, and now most trans are running 80-100. I used the same LNB on both dishes. I had some problems with the switch test until I checked the SD box. Then, the switch test went from 38 to 50 tests, and detected the 105 OK. Trans 1-19 are 80-100. 20 is 65, 21 is 48, 22 is 0, 23 is 60, and 24 is 80. I was really suprised that the signal increased that much with the larger dish. The 121 #s went up some as well, but is actually in line with the 105 sigs now. So, I guess that the bigger the dish the better with the FSS locations. Has anyone else gotten any similar results?

    Yes, with a 35.5x26.5 dish all I could get was the low 70s for 105. On 121, using the same dish I was getting 100-110. When I switched out the dish for a SuperDish 121 dropped down to 100ish. I was surprised that the SuperDish only dropped the signal about 10 points given its smaller size vertically.

    105 gave me fits trying to aim it since it was so weak.

    I had a lot of problems trying to get the 105 with the smaller dish. I have yet to do a SD on the 105. Myself, I think I would stick with seperate dishes since I have heard so much about signal problems with the 110/119 on the SDs.

    I just installed the SD and cannot yet get anything from 105 . 119 and 110 are both above 100 but nothing from 105 yet.. been tweaking for about an hour. I heard the signal is weak here in Florida. Has anyone gotten a decent signal from 105 with the SD down here?

    I have separate dishes for 110, 119, and 61.5. I just have the single LNB on the superdish.

    As far as getting 105 it is so faint that it took me a while to lock on to it, I tried a meter but it was impossible since I kept getting adjacent satellites. So, I had to drag a TV up there and watched the reciever bar. You just have to barely move the dish and wait 20 seconds before you move the dish again. I would count 30 buzzer soundings on the TV and move it again. I managed to get 105 in about 20 minutes this way.

    I had some of the same problems. My meter would pick it up, but the receiver wouldn't. Also, since the P* LNBs are line locked, if you forgot to have the screen on the right transponder, you don't get anything either... :D

    Once I went to the larger dish, I pegged it fairly easily. I guess the bigger the better......

    Remember that the PrimeStar lnbf's have to be rotated to have the correct polarity which would have an affect on the signal if not rotated to the correct spot.

    Yeah, I know. Had a problem with that when I switched out the LNB to see if I could duplicate my efforts and forgot to adjust the barrel. I did notice that it didn't seem to matter as long as it was within a certain amount of adjustment. I really couldn't get much fine tuning out of it.

    So with the new 105* sat how much should our signal strength go up? Anybody heard anything yet?

    Supposedly. I just switched the 105 onto my 721 with an SW64, and got 80+ on all 24 transponders(the 721 only goes to 100, not 125).

    I would say that we could expect to get the same signal strengths if not higher than what we could get from 121.

    Sorry to bug in, for some reasons I cannot find any signal for 121 or 105. I'm using P* f-76u dish and pt5500 lnbf. I keep getting some 119 signal :confused:

    Northern...
    Did you rotate the LNBF to correct polarity?

    I can't get it either, have a signal above 90 on 119 and 110,(SD+dp34)
    and for a few seconds I had about 30 on the 105, but that didn't last.
    Itll probably be easier once I get the cast off my arm :joy:

    If you are getting 119 are you useing a KU-FSS or KU-DBS LNB? The LNB is not the same as the ones used for 110/119 (KU-DBS) it is a Ku-FSS for 121/105.

    I did rotate the lnb, but not sure if its right.
    Isn't "pantsat pt5500" a ku-fss lnb??
    I got channels like hbo-e,bet,bravo,animl....

    I'm using the Ku-FSS with a dp-34 and have tried just about everything (for 3 hours today) and can't get 105 at all. IS there a weaker signal in Florida.
    I looked at the 105 footprint and it doesn't look like there should be any problem.

    You would need to use the H side if you are using the PrimeStar lnbf without a switch.

    If you are using anything other than a super dish, you have to be using a legacy swithc, or your system will not see the lnb. If you are using a P* style dish, you need to connect port 1A to the V and port 1B to the H on the LNB. The V is for odd, and the h is for even. lecagcy LNBs will NOT work with any dish pro switches. While DP uses 19.6 volts, it stacks the evens into the 1650-2150Mhz band, and the P* or legacy LNBs will only send it back on the 850-1450Mhz band. You will need either an SW44 or SW64.

    Larry ,I'm using a SD 105 with the 3 lnb setup.. into the dp34 then a dish pro adapter to my 4900. I'm thinking of putting 110 and 119 on a different dish
    and use the SD for 105 only. any opinions about trying that?
