No Signal on Horizontal Transponders
|
Silver Member Username: KrishnPost Number: 165 Registered: Sep-06 | On satellites connected to port 1 and 4 of DisEqc switch, getting signal only on vertical transponders and no signal on any horizontal transponders However port 2 and 3 has signal on both Horizontal and vertical transponders. Is it due to bad DisEqc switch or some other problem? |

Silver Member Username: LomnaPost Number: 295 Registered: Dec-07 | do you get signal from both tps when not using any switch ??? |
|
Silver Member Username: KrishnPost Number: 166 Registered: Sep-06 | Have not tried it since I do not have a long cable or small TV to test it outside |
|
Silver Member Username: LomnaPost Number: 296 Registered: Dec-07 | It is highly likely that it is the signal from the sat and not the switch causing this.By the way what sat giving you the trouble and where you located ? |

Silver Member Username: KrishnPost Number: 167 Registered: Sep-06 | Thanks Devin. Replaced the DisEqc switch to Cheita from original Coo*lsat and it is working. Also a loose connection on one of the LNB's as well |

Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3093 Registered: Oct-06 | Yor switch is fine Something else is wrong If yor switch is bad yo won't get any signal V or H I bet yo got a short or improper wiring due to use of splitter or other short type Anytime yo short polarity is exactly what happens no Horizontal only Vertical That's a short my friend not a bad switch Yo'll change yor switch yo'll get the same problem If yo list me all yor hardware I'll get yo up and runing in few seconds List no stories LNBs, dish, switch receivers, cables, etc. Snap and seal coax connectors are the way to go Proper cramping is required Simple short problems create big problems |

Silver Member Username: KrishnPost Number: 168 Registered: Sep-06 | Thanks for the offer King it is up and going now. It was a bad switch anyway and probably it was a short that was solved by replacing some cables whose metallic ends had broken. However did fry a DisEqc switch, even though I had powered off the receiver and even unplugged it, wonder how? 2 receivers connected to two DisEqc switches, one port on CB2008 dual LNB on 33" for 188.8/119 and three Calamp dual LNB on three 18" DTV dish - the other receiver was powered on which fired the other DisEqc switch. Dual LNB's when powered on by one receiver just broadcasts the signal on both outputs and it does not confine its output only for the receiver from which the request originated. This is true for CB2008A and CalAmp dual output LNB's, may be there are dual output LNB's that do not broadcast, but that is not the case with these two dual output LNB's. However it is possible to mix and match - watch Horizontal transponder one one receiver and Vertical transponder on the other receiver and vice versa. Please let me know if there are any dual output LNB's that restricts its output to the receiver that originated it? Can you build you own cables with snap and seal coax connectors - any idea how much the equipment costs? |

Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3096 Registered: Oct-06 | If yor up and runing then problem is solved yo don't need me I still think yo had a short applied on 2 receivers due to some splitting coax or short coax due to bad crimp or use of splitter etc. I have no idea what yor talking about here: "This is true for CB2008A and CalAmp dual output LNB's, may be there are dual output LNB's that do not broadcast, but that is not the case with these two dual output LNB's." "Please let me know if there are any dual output LNB's that restricts its output to the receiver that originated it?"  One of the most important factors in any type of installations is WIRING. I advice anyone Armature or Professional to use Good wiring. RG-6 Quad Shield is the way to go: RG-6 double shield is OK too - There are so many different Coax cables Rg-58,59 etc. - There is also RG-6 double shield as well as quad shield. - Quad shield is only 5 or 10 cents more per foot. IT IS WHAT I RECOMMEND. - Will other cables work? yes they will. - RG-6 Best proven product in the market today. Very little or no DB loss. Great for up to 150 feet before your DISEqC Switch - Compression connectors, snap and seal. Great weather resistant. Less problems - Ground your metal coupler or DISEqC switches etc. - Your connection will last yo 50 years good for all weather condirions. Sold at home depo Or e-bay satellite e-store etc. |

Silver Member Username: KrishnPost Number: 170 Registered: Sep-06 | Let me try another shot at explaining my problem. Nalin or any one knowledgable can chip in. Problem description more simple terms: Setup: i) Two independent FTA receivers in different rooms, each connected to a DisEqc switch. ii) Port 1 of both the DisEqc switches are connected by coaxial cable to the individual output of the common CB2008A dual output LNB sitting on a 33" Fortec Star dish aimed at 118.7/119 iii) Port 2 of both the DisEqc switches are connected by coaxial cable to the individual output of the common Calamp dual output LNB sitting on a 18" dish Direct TV dish aimed at 110 Problem description: Possible to simultaneously view any two channels on both receivers as long as the channel is from port 1. Any combination of Horizontal or Vertical or 118.7 or 119 is fine. When either one receiver is on port 1 viewing any channels on 118.7/119, it is impossible to view any channels on 110 on the other receiver, the signal quality on 110 is zero with no signal message Now just turn off the receiver that was on 118.7/119, the signal quality on the other receiver for 110 is back to 97%. Diagnostic Hypothesis: When one receiver is on 118.7/119, the signal from the CB2008A LNB is not sent only to the DisEqc switch/receiver from which it was requested, the signal is sent to both the DisEqc switches/ receivers. Now the dish specification for the 33 inch dish is: KU -- Band Gain @12.5 GHz 38.24 dB. The DisEqc switch specification is Isolation: >25dB. Probably it is the limit. This seems to be the logical explanation of the problem. I have read other places also that dual output LNB's do send signals on both outputs, unless it is overridden by a request for signal from the other port also. Possible solution: i) Replace the CB2008A, with another Dual output LNB that does not send signal back to both DisEqC or ii) find a DisEqc switch that has isolation around 40dB or iii) Place the Calamp aimed at 110 on a bracket next to CB2008A aimed at 118.7/119 on the same 33" dish Please let me know what option would be best to try? |

Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2927 Registered: Jan-08 | Meisha for two receiver you need LNBs with 2 output and 1 diseq switch hook for each output one switch for each receivers or you can buy 2 switch with high and low voltage like this one: http://www.sadoun.com/Sat/Products/Channel-Master/6254IFD%20ChannelMaster%20Mult iswitch4%20copy.jpg Your ploblem is the because 2 receivers give high voltage on LNB Horizontal signal 13 volts Vertical signal 18 volts If you get on 2 receivers 2 channels on horizontal thats OK but if one of two is on Vertical you lost signal on the other because you give high voltage on LNB I hope that help you to understand  |

Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2928 Registered: Jan-08 | Thi is the good way to connect 2 receiver http://sadoun.com/Sat/Installation/Multi-LNBF/2-receiver-4-lnbfs.htm |
|
Silver Member Username: KrishnPost Number: 171 Registered: Sep-06 | Thanks Plymouth. What you are saying makes sense if two receivers are daisy chained - taking IF output from one receiver and feeding to the another receiver However two independent receivers connected to two different DisEqc should not cause this problem, unless the Dual output LNB's sends signals to both DisEqc switch not just one DisEqC switch. As I mentioned earlier in the thread,I did fry a DisEqc switch, since I had not powered off the other receiver and the other receiver was switched on |

Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3098 Registered: Oct-06 | Subash Yor possible solutions are irrelevant to this problem Like I always say Simple short problem can act like a big complicated problem Best solution is to stay with the basics I was hoping yo list yor hardware and antenna settings I don't know what brand of receiver yo are using Yo got a short my friend It's a short!!! no doubt wiring short And usually it's operator's error I asked for receiver's name cuz on some Pansats if capacitor C-1 and C-2 bad it can act like a short Make sure yo go from LNBF out to LNB in of yor receiver Make sure it's NOT going To LOOP OUT It sounds like yo got LOOP out somewhere on yor wiring I'm almost willing to bet LOOP OUT is being used It's hard to know yor wiring I'm not with yo Anything possible  Why don't yo start with few basics: RECEIVER ONE - 118/119 to port-1 - assign (antenna setting) DISEqC port-1 RECEIVER TWO - 110 to port-2 - assign (antenna setting) DISEqC port-2 - Check to see if it works properly - Then add 110 to receiver-1 - Check to see if it works properly - Then add 118/119 to receiver-2 Everytime yo change coax Power must be off to avoid burning internal coil of DISEqC switch No need to get frustrated I assure yo if everything is wired correctly there will be no conflict the V&H conflict is due to a short To find the short is a step by step process of elimination Feel free to ask any question When it gets to hardware There is nothing I can't handle |

Silver Member Username: KrishnPost Number: 172 Registered: Sep-06 | King: Sorry not good at diagrams thats why did not post one. Your diagram is accurate - details to be added: 119 is CB2008A on 33" 110 is Calamp dual on 18" DTV dish RCV-1 Pansat 2700A RCV-2 Sonicview 360 Elite. Yes - answer a fundamental electrical engineering question. RCV-1 is on 119, is the signal being sent to just RCV-1 or to both RCV-1 and RCV-2? Probably Nalin was mentioning this post? [link removed] |
|
Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3100 Registered: Oct-06 | Simple details to be added Yo can treat 118/119 as one satellite assigned to port-1 Look One advice I'll give yo Yo follow my post#3098 and yo'll find the problem in seconds Don't confuse yorself by listening to more than one person in yor situation Yo got a short It's that simple Did yo at least look at back of yor receiver to see if yo are going to LOOP OUT instead of LNB IN? |
|
Silver Member Username: KrishnPost Number: 173 Registered: Sep-06 | It is LNB IN and not LOOP OUT. Agreed 118/119 is in in fact dual band LNB so it is just one sat. Still need to find out the answer to the fundamental electrical engineering question - do you know the answer? |

Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3102 Registered: Oct-06 | "answer a fundamental electrical engineering question. RCV-1 is on 119, is the signal being sent to just RCV-1 or to both RCV-1 and RCV-2?" - Coming In to receiver LNB in is either 13V or 18V - 13V is Vertical 18V is horizontal polarity - Voltage decides specific polarity - When 13V and 18V applied at same time 18V over-rides for Horizontal - When either polarity is selected signal comes from LNB to receiver - LNB has to outlets - One goes to receiver-1 other goes to receiver-2 - 2 signals out of LNB goes to 2 receivers LNB splits signal using internal logic gate So as long as yo got connection from LNB to receiver-X that receiver-X will expect to get connection of both V&H IF Only H is on There must be bridge over-rides Yo got a short somehow Due to signal split 18V bridge Or soemthing faulty Possible Pansat 2700 has something to do with that short Bad bin can do that too Also possible LNB is got internal short Anything possible Do what I advised yo above This is how to find the smoking gun 118/119 to rcvr-1 110 to rcvr-2 (test for problems) If yo do find problems no need to go further If no problems found continue on Then add 110 to rcvr-1 (test for problems) No problems then continue on Then add 119 to rcvr-2 (test for problems) Basic idea is to add one satellite at a time This is what I would do to find smoking gun So to answer yor question If there is a connection there is an expected signal No connection means no signal |

Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2959 Registered: Jan-08 | Iroy You can use only one, but you need many input with 13 volts and 18 volts, one for each LNBs. It,s less expensive to buy 2 switchs |

|
Silver Member Username: KrishnPost Number: 175 Registered: Sep-06 | King: I did follow your procedure,it answered the question I was asking about Dual LNB's broadcasting or sending signal only to the receiver that is requesting it. Please not all are Dual LNB's and two independent DisEqc Receiver 1 ---------- 118.7 & 119 DisEqc: Port 1 LNB Power: on Receiver 2 ---------- 118.7 & 119 DisEqc: Port 1 LNB Power: on If Receiver 1 has H channel on 119 any H or V channel is available for 119 on Receiver 2 If Receiver 1 has V channel on 119 any V or H channel is available for 119 on Receiver 2 So goes the myth about not being able to view combination of H and V channels on different receivers and more interestingly: Receiver 1 ---------- 118.7 & 119 DisEqc: Port 1 LNB Power: on 110 DisEqc - Port 2 LNB Power: on Receiver 2 ---------- 118.7 & 119 DisEqc: off LNB Power: off 110 DisEqc - Port 2 LNB Power: on All channels say no signal for 110 on Receiver 2 and the more interesting part is - if Receiver 1 has H channel on 119, any H channel on 119 is available in Receiver 2 and any V channel is no signal. Very similar behavior if Receiver 1 has V channel 119 - any V channel is available on Receiver 2 on 119. Note that it does not matter even if the DisEqc is off at port 1 on Receiver 2, the signal is still coming in to the DisEqc from the LNB and on to the receiver itself. So the questions are very simple: (i) Dual LNB is sending signals on both coax to the two DisEqc even though the request is coming from just one coax. It it a faulty LNB or Dual LNB design itself? (ii) DisEqc is not blocking the unsolicited signal coming in at Port 1, it is passing it on through the coax to the receiver - faulty DisEqc or DisEqc design itself? |

Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2964 Registered: Jan-08 | Subash Give me info on this CB2008A LNB with 2 output 2 outputs one for 118.7 and one for 119 or 1 output each for both? |
|
Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2965 Registered: Jan-08 | Subash You can not connect 2 receivers on this LNB I read spec. and it seems to be one out for 118.7 and one out for 119 thats the ploblem. That mix the voltage thats why you cannot select Vertical and Horizontal. Try to connect this LNB on 1 Diseq switch only and give me reply. |
|
Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3106 Registered: Oct-06 | Yor dual LNB should have 2 independent outlets 118/119 is considered one orbital location thru 1-LNB i.e. treated as one satellite 2 frequency scans 2 outputs 4 possible combinations - V&V - V&H - H&V - H&H The combination should be independent no matter which receiver is going to Same with DISEqC 2 independent switches selectable by rcvr (4-selectable inputs to 1-output) I do see the part yo say DISEqC is off but signal still coming to receiver I strongly believe yo got a short on yor Pansat 2700 To confirm this the only way to do so is try a completely different working FTA receiver other than pansat If it turns out Pansat problem which I'm NOW 70% certain It will most likely be 1, 2 or even 3 bad capacitors The other 2 possibilities Poor wiring or wrong setup or both I don't like to rule out any possibility What I don't think is DISEqC switch Also a possibilty yor pansat damaged DISEqC switch So it doesn't matter how many DISEqc switch yo snap Yor search is to find the source of the problem not the effect Yo might be dealing with 2 problems now Not just one Good Luck |

Silver Member Username: KrishnPost Number: 177 Registered: Sep-06 | Plymouth: It is band stacked for 118.7 and 119 and both 118.7 & 119 is available on either reciever. Problem is signal interfrence on 110. Here are the CB2008A specs: http://www.worldwidesatellites.com/catalog/product_info.php?products_id=250&osCs id=0c6eee7e79100651a56007c9c07a |

Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2977 Registered: Jan-08 | Subash OK this LNB have 2 output with each output for both 119 and 118.7, thats the good one. Your problem is OK or not? |
|
Silver Member Username: KrishnPost Number: 178 Registered: Sep-06 | Plymouth: Too many things have been talked in this thread, should have started a new thread. The current problem stated briefly is dual LNB's on different dishes (one CB2008A on 33" and others Calamp dual LNB on 18") are connected to two DisEqc switches. (i) When either one recv is switched off, all dishes are OK on other recv. (ii) Any combination of dishes can be viewed at the same time on both recv as long as big dish which has CB2008A is not used on both recv (iii) Moment CB2008A is used on either recv, then only CB2008A can be viewed on other recv, any other dish is no signal on other recv.

Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2981 Registered: Jan-08 | Subash I have a dish with motor but i think you need to setup Legacy Switch on "Sw21" on each receiver, because 2 signals come from each output.Need to set to port 1 on each receiver too. That what i see on spec of CB2008A LNB |
|
Silver Member Username: KrishnPost Number: 179 Registered: Sep-06 | Plymouth: You might be right, dual LNB's and two DisEqc's may not be the right solution for viewing two different channels originating from different sat at the same time. Need to get better knowledge of DisEqc, was reading that DisEqC 1.0 just receives commands and responds with signals. No confirmation sent back regarding sat communication success or failure etc. |
|
Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2982 Registered: Jan-08 | Subash You need the 2 diseq switch each on port 1, but in sat setup set legacy switch on SW21 for select 119 and 118.7, these 2 have 2 different freq. If you dont assign this the receiver select it by default, not what we want. Good luck |
|
Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2983 Registered: Jan-08 | You hook as King post 3098 on this thread and select sw21 dish 1 for 119 and sw21 dish 2 for 118.7 on legacy SW. If they dont work select sw21 for 118.7 and sw21 dish 2 for 119 |
|
Silver Member Username: KrishnPost Number: 180 Registered: Sep-06 | Plymouth: If I understand your setup correctly an additional LNB is needed for 119 and use CB2008A for only 118.7 so that two rec's can be connected. Since CB2008A is band stacked or "Dual output LNB with Dual polarization". Only two outputs come out one for each receiver. Are you suggesting to connect SW21 output to DisEqc port1? As long as it blocks unsolicited input which is causing signal interference it is fine. What about having all other DisEqc on 22Khz off and CB2008A on 22kHz on - will that block unsolicited signal? |
|
Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2984 Registered: Jan-08 | Subash No you dont need additional LNB CB2008A is Legacy switch built-in |
|
Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3112 Registered: Oct-06 | No Plymouh/Sabash I wouldn't touch SW21 at all He's got a short Great chance coming from P-2700 Like I said try a differnet working FTA reciver other than Pansat Process of elemination To rule out one possibilty at a time I don't have that LNB CB2008A But I strngly believe it is a working dual LNB |
|
Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3113 Registered: Oct-06 | Actually I do have a theory I do think the 2700 is yor smoking gun What's hapening here is 118 requires a Universal LNB with Ku =Lo settings 119 requires a Single/Universal with Ku=High settings I do think yor 2700 is not capable to support both KuHi/KuLo at same settings This is why I'm asking to change 2700 Yor LNB is fine A technical problem like this could of been dtected much erlier if yo would of posted yor detailed settings this should include LNB selection/frq Frequency by LNB is known as internal clock freq Yor 2700 is so outdated it may not be able to support two freq spans I still can't rule out a simple capacitor short But if would simply follow my steps when I told yo Yo could of detected it much earlier Replace yor 2700 List yor detailed settings Come back and thank me King |

Gold Member Username: PlymouthQuebec city, Quebec Canada Post Number: 2986 Registered: Jan-08 | King look at spec: http://www.worldwidesatellites.com/catalog/product_info.php?products_id=250&osCs id=0c6eee7e79100651a56007c9c07a This LNB have 2 outputs and in built Legacy sw. You cant selected 118.7 and 119 in same time, because this 2 sats use different Freq., you need to use Legacy switch. |

Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3115 Registered: Oct-06 | I think he got 2 problems not just one P-2700 LNB freq conflict causing all kinds of short Plus now most likely damaged port-2 on DISEqC that has 110W P-2500 and P-2700 should be completely phased out of PTA |
|
Silver Member Username: KrishnPost Number: 182 Registered: Sep-06 | King: Not sure if one can get 97% quality for 110, when other rcv is not on 119, if port 2 is damaged. May be you are right and I am wrong on this one? |
|
Silver Member Username: KrishnPost Number: 183 Registered: Sep-06 | After some reading about DisEqc version 1.0 it appears that DisEqc is not really a switch, since it does not establish a circuit connection with an LNB and then tear it down. All it does is just fork power from rec to alternate destination points - LNB's, send power and receive the signals back from the LNB's This explains the interference, since a stronger signal is coming back from the LNB from a bigger dish - since the other rec has powered it on, causing interference for a weaker signal coming from a smaller dish. The next point of exploration is dual output LNB's. Are there any dual LNB's that restricts returning the signal to only the output from which signal was requested or all dual output LNB's return signal to both output points? |
|
Gold Member Username: TapemanNew York City in-HD, NY Post Number: 3128 Registered: Oct-06 | DISEqC is a 4-input to one output switch It is a switch controlled by yor antenna port selection The DC is another passive 2 input to 1-output switch 2-input is for V&H So it is 2 types of switches 4-input high frequency AC switch 2 input DC voltage switch All together like 8 to 1 switch |
|
Silver Member Username: KrishnPost Number: 186 Registered: Sep-06 | King: You are right, however the issue is it one and only one input at a time or does it permit more than one input concurrently. In strict definition Switch does provide one input only at a time by establishing a dedicated temporary connection for the duration and tears it down when not needed. In a true switch, if the rec has requested a signal from port 2, then only signal originating from LNB that is on port 2 can make its way to the coax that is connected to the rec. Any signal that is coming in from any other point - port 1, port 3 or port 4 cannot come in to the coax. The DisEqc does not work as stated above, it does not block signals coming in from other ports - port 1, port 3 or port 4. Please let me know if I am not correct? |
