Bad Legacy twin?

[RonnieT]

I am wondering if I have a bad LNB or just a sign of the times?
I have a Twin Legacy, one cable to one VS Ultra pointed at 110 and 119
Have been noting black screens on 110 channels with good S but no Q.
So I re-aimed the small pan and got a good S & Q on both sats but when did the auto scan still came up with short list of channels.
Clear skys, thought the ultra high winds of late has moved the dish some. But could it be the Twin not working like it should?
Did this sevral times after doing the Factory default.
Any hints?
Thanks

The legacy twin is getting old yes, I really never had good luck using that particular lnb and the VS. I always replaced w/ the dp type twin in the past.

[RonnieT]

I may have an old DP Twin? will look.
I was trying for 2 sats one cable no external switch and maybe later add another box later on another cable.
I guess the DP twin will do that? Do you know what I should select for the DP twin on VS set up as for lnb type, switch type, tone, etc?

I am a little rusty on the settings of the VS, but I think the LNB type will be obvious. I think it sayes OCS-DP.

Your switch type will be off, and the LNB frequency will be 12500, and you will want diseqc #1 for 119 and diseqc #2 for 110.

I had a DP twin and put it on, I wasnt sure about the settings so I guessed, I guessed wrong because I got worse results than with the Legacy Twin.
I used these.
sat. Echo 7
Lnb Pow.= on
Lnb Typ.= OCS-Dp
Lnb Frq. =11250
22Khz = off
tp frq.= 12297
disq. 1.0= None
Motor= off
Legacy Sw =sw21-dish1


Same for Ech 110 but
tp Frq.=12224
and
Legacy Switch = Sw21-dish 2

Will try your suggestions tomorrow and post back with results

for dp use diseqc settings not sw-21

[brotherstores]

Follow DU's advice and turn off your SW-21 setting.

Also make sure that you do not have a DPP twin versus a DP twin. The obvious difference will be a third port on the LNB for a wing dish. The DPP LNBs require more power than the typical FTA receiver can produce.

If you are having more issues, than you might need to check your dish alignment.

May have to re-aim although I am getting great S & Q on both sats.
My setting used for the DP twin are
sat. Echo 7
Lnb Pow.= on
Lnb Typ.= OCS-Dp
Lnb Frq. =11250
22Khz = off
tp frq.= 12297
disq. 1.0= PORT 1
Motor= off
Legacy Sw =none

difference on Echo 10 were

Disq. 1.0 = port 2
and
Tp Freq.=12224

But auto scanned less channels than before. last scanned did back on last ultra update was scanned 598 channels
this time less than 200 total
Yes it is a Dp twin , w/correct logo and only 2 terminals
Thanks

[RonnieT]

Something I believe is wrong prehaps with the Ultra?
Still after re-aiming only getting about 200 auto scanned between the 2.
I am using a TP freq. of 12297 on Echo 7 and port 1.
I get very little Q at that setting , lots more when I set to port 2.
I dont know if the ultra is not sending a signal to the Lnb or? but its about the same with the DP twin as was with the Legacy twin.
I may be off on the re-aim espically if the VS is not switching to port 1 as I am using 119 to aim.
May have to set up using a legacy single to aim with?
any clues?
thanks

Dish is still not aligned, menu setup is correct as in post #8. When you set up the sat only scan 1 sat at a time, then set up the second sat and scan that sat.

[RonnieT]

Yes scanned one at a time and 110 is the better of the 2.
I found a Dishpro quad also that I have.
I suspect the alignment of the dish. I am having difficulty aligning it, although I have the correct readings for my area
I am using a sound/needle meter and also watching for the S & Q on the receiver while set up on 119. am not getting much Q
at all . I know to use 119 to set and then Skew for 110 but right now my 110 is best.
Should I use a single legacy to get 119 pointed?
I have a single cable off of one LNB terminal to the back of the ultra. no switches, Correct?
all help is taken seriously,
Thanks

was 2 bad LNBs, both were used.
The first was the Leg. twin that I suspected. all the while putting on a bad DP twin and started chasing a ghost.
I was suspect of it because of slow scanning and no polarity switching while scanning. So re-aimed the dish one last time with a single legacy at the 119 spot and with correct settings for that LNB and got huge Q gains.
Changed LNB back to DP twin and same story again.
So switched to a DP Quad I had and that solved it, scanned over 530 on both and the polarity switched back an forth easily.
Thanks for the help. Who would have guessed?
I was suspect of months of continual winds of over 50 MPH here, so finally caught a good calm day to look at it.
I appreciate the help and hope this helps someone.

If you think the dish is moving due to the winds I would pin it down, (once its re-aligned) this involves drilling a 1/4" through hole through the mount and mast then using a 2 inch 1/4" bolt and Nylock nut you pin it so it wont twist.

If the mast is shaking around you can go to an electrical supply house and get some inch and a half standoffs like the ones used on the electrical power drops to a house, then using some conduit you make the supports to keep the mast stable
