Chris's C Band list
(Third try to post this)
Okay: you asked for it and here it is. These are the results of detailed, 4Mhz/step blind scans with the Merc II. To recap: the C Band setup is a 120cm dish, GeoSat dual output C band lnb and DG-380 Motor. I'll show what the Fortec indicates for the TP followed by the Lyngsat listing for the same one. The first thing you'll notice is that my polarities are the opposite of theirs! I have no idea why- the "0" marking on the back of the lnb is pointing straight up, and the only way I could be off like that is if I was 90 or 270 degrees out. We'll start in the east and work west. ISS 805 (55.5W)- Great signal on all tps TV: 3858/V/4449 (Lyngsat:3858/H/4444-2/3) Scans in as Scopus Net Tech; Panamerica channel 4097/V/5250 (Lyngsat:4097/H/5247-3/4) Canal 4, 10 (Nicaraguan Mux) 4119/V/3012 (Lyngsat:4119/V/3100-2/3) Edupol distance learning RADIO: 3935/V/3258 (Lyngsat: 3936/H/3255-2/3) BBC radio feeds 4083/V/10328 (Lyngsat: 4084/H/10318-3/4) Radio Sonora, Fiesta, Tropicalida, Galaxia, Alfa, Ranchera INTEL 9 (58W) TV: 3799/V/4449 (no Lyngsat listing) Canal 8, studio news feed? 3880/V/27690 (Lyngsat: 3880/H/27690-7/8) Chinese state TV (CCTV) 4, 9, F, E, YTN, Arirang (Korea). Despite a solid 35% signal quality this tp is so broken up it's unwatchable for me. Maybe it's the low FEC value? 4039/V/16188 (Lyngsat: 4040/H/16180-1/2) NHK World 4 channels, 525 and 625 lines, english and japanese. 4119/H/27531 (Lyngsat: 4120/V/27500-3/4) Yes Italia, RAI News 24, Future News, Salute TV. The opposite of the CCTV tp above- with just 25-27% signal quality I can watch this one just fine. 4125/V/2941 (Lyngsat: 4125/H/2941-3/4) Bethel TV, spanish language religious channel RADIO: 4039/V/16188 (same as TV) Scans in as "Radio 1, 2, 3, 4" NHK World radio, including a slightly creepy (for me) station ID in english and japanese 3807/V/3430 (Lyngsat: 3805/H/3428-3/4) China Radio International, 28 channels 4119/H/27531 (same as TV) "Radio Al Ddikr", "Radio Music", "Orient Radio", RAI radio service, RAI radio Australia, "RI Anni 60", "Radio 2Moro", "Radio Voice of Char." AMC 6 (72W) TV: 3785/H/4344 (Lyngsat: 3786/V/4340-3/4) NASA interactive channel, scans in a "Ch 1" 3974/H/8688, 3803/H/4344 (no Lyngsat listing) both scan in as "Ch 3", no video, just a buzzing sound for audio...some sort of data? 3953/H/4168 (Lyngsat:3953/V/4167-3/4) Pennsylvania Cable Network 4039/H/26688 (Lyngsat: 4040/V/26665-3/4) Nasa education channels ("HQ 1, 2, 3, 4") No radio on AMC6 AMC 3 (87W) TV: 3829/V/3523 (no Lyngsat listing) Michigan Government TV (reg. and AC-3, "MGTV") 4076/H/3027 (no Lyngsat listing) Roberts Communications dog racing feed 3834/V/2736 (Lyngsat: 3833/H/2734-5/6) THiS TV network (AC-3) One radio channel scanned in but there was no audio. GALAXY 28 (89W) Here's where the trouble starts- no tps of its own showed up, they were all from Galaxy 17, the next sat over. GALAXY 17 (91W) TV: 4078/V/2898 (Lyngsat:4079/H/2900-3/4) GEMS television shopping channel 3919/V/26031 (Lyngsat: 3920/H/26000-3/4) Various versions of EWTN Catholic network (19 channels) 4013/V/6625 (Lyngsat:4014/H/6620-1/2) The Word Network (reg. and AC-3) 3820/H/30031 (Lyngsat:3820/V/30000-5/6) Fox Network feeds (color bars, reg and AC-3, scans in as "Network B/U" and "Network B/U-dig") 3859/H/30031 (Lyngsat:3860/V/30000-5/6) Info Card "This programming is available on another channel in your area" (Reg. and AC-3, scans in as "Future" and "Future-Dig") RADIO: 3919/V/26031 (same as TV) Seven channels of EWTN radio GALAXY 3-C (95W) TV: I'm not going to type them all out but there are 25 or so dog and horse racing feeds from Roberts Communications, they all have a 3074 SR and 3/4 FEC, and the signal on all of them is very weak. GALAXY 19 (97W) TV: 3780/H/27625 (Lyngsat:3780/V/27600) scans in as "HD Clear", Lyngsat just says "feeds". No video for me, nothing audible either. 3820/H/26031 (Lyngsat: 3820/H/29270-7/8) Scans in as "GDMX 2, 3, 4, 5, 6", I can hear the audio but no picture, Lyngsat says "CBS feeds" in Digicipher2 So, to sum up, there's nothing watchable for me on this one...what a contrast to Ku band on this sat! GALAXY 16 (99W) TV: 3735/V/3781 (Lyngsat:3735/H/3776-3/4) WAPA America, San Juan PR- This one is a really strong signal (60-70% quality) and can be used as a reference point, they have the "WAPA" logo on all the time so you know what you're watching. 3844/V/15047 (Lyngsat: 3845/H/15030-3/4) Caribbean Mux: NBC, CW, THiS TV, etc. 3999/V/26406 (Lyngsat: 4000/H/26400-3/4) World Harvest TV (reg and AC-3) and LESEA network 3716/H/4344...Golden Eagle Broadcasting; but this is supposed to be on AMC 1, the next sat over, but scanning that one doesn't produce this channel!? RADIO: 3999/V/26406 (same as TV) Angel radio religious channels. AMC 4 (101W)...Nothing at scan time, however I did pick up the New York State Legislature channel last week, very badly. From here on out to the west, things get very iffy, and there's not much I can see reliably. I'll try some more and put the results up if I get any.

...and then something pops up in the west:
GALAXY 23 (121W) 3706/V/5641 (Lyngsat: 3707/H/5632-3/4) Sportstime Ohio- good signal 3719/V/3004 (Lyngsat: 3719/H/3002-7/8) TWV, Washington State public affairs 3723/V/3004 (Lyngsat: 3724/H/3002-3/4) Sportsman's Channel. I could also get AYM Sports on one of the Satmex satellites. CN |

Hi Chris,
I thought you might want to see my C-Band list for the 1.2m dish. I'm using a Geosatpro CK1 and I also was never able to get the KU-Band to work either. The Conical Scalar rings really helps though. Did you ever make one from Satcom1's plans? AMC 6: Penn Cable Net and the NASA channels AMC 3: MGTV and ThisTv Galaxy 17: Fox Movie Channel, all of the EWTN MUX channel, KHIZ, Barstow, Ca and the Divds test cards Galaxy 16: All of the Virgin Island Networks, World Harvest, and the Lesea Network AMC 4: Golden Eagle and WAPA TV Anik F1: Lots of PPV channels that I could lock, but couldn’t watch Satmex 6: Uteg, AGS TV, SYM Sports, TV Nuevo Leon. I stopped there, but could have locked on many, many more with excellent signal quality. However, I don’t speak Spanish and didn’t really need the channels. Satmex 5: Canals 11 through 28 and many other Spanish channels. Again, I didn’t try to get them all. But signal quality was excellent. Galaxy 23: Sports Time Ohio, Sportsman Channel and Jewelry TV Galaxy 13: Louisiana Super Station and Apostolic Oneness channel AMC 11: A&E TV Networks (PPV) and two QVC channels Galaxy 15: The California Channel, Classic Arts Showcase AMC 10: HSN (although pixilated) |

To answer Vitruvius's question...NOPE! Really- I don't have space for a "real" dish, and I'm satisfied with the results of this one. Most likely I'll just leave the dish parked at 58 so I can see my favorite NHK and occasionally go over to ISS805 for the BBC radio.
Electrolaw: What part of the country are you in? It's interesting that you're picking up some channels from the west I couldn't get, but you don't have the far eastern ones that I do. It's quite disappointing, because the one thing I really wanted to find was the plethora of free Music Choice channels on Galaxy 14, I believe, and I can't get a single tp on that one. Anik F1 I could get a couple tps but no locks on any channels. And yet I can pick up three channels on Galaxy 23, but they aren't the same ones you got. BTW, take a close look, you've got a mixup between Galaxy 16 and AMC 4- WAPA is supposed to be on Galaxy 16, for you it's bleeding over to the west, for me it bleeds into Galaxy 19 and even further, so for me it's bleeding over to the east. I've found the only way to minimize the problems is to find a tp you know is in a given place (after I've used USALS initially and scanned in) and peak that one using Diseq 1.2, then scan again and I can usually turn up another tp or two on that sat, and the ones adjacent will get so broken up or disappear that you know they're on the next sat over. One thing I did do this evening was get up there and turn the lnb 90 degrees, so "0" is at the 9:00 position, and started rescanning everything; I'm getting some different things and the receiver is recognizing pre-stored tps now. I need to try the homemade scalar rings but it's going to have to wait as work is getting busy and I'm not going to have as much time for this (for a few weeks anyway). CN |

Chris,
I'm in Northern California. You are right about the bleed-over. What we really need is the old type of Corotor where you can adjust the skew. Search this on YouTube: Waveguide Polariser AV-COMM Test It's in German, but this guy has come up with a solution for the skew problem on a small dish. I also did one other experiment with my 1.2m dish. I slaved my DSR920 4DTV receiver to the loop-out of my Viewsat Ultra and went to G1-3 and got the 4DTV guide to lock. I then went to W-5 and locked (with plenty of signal quality) W-5 603 (FTA American Life Network) and all of the premium movie channels. I could subscribe to these channels now if I wanted to. I then got all of the free 4DTV channels to lock on GB with good signal quality. I haven't tried any of the other 4DTV satellites, but I would think that results would be similar. I just realized that the free music channels you are going after on Galaxy 14 are DGII. You will have to have a 4DTV receiver to get them. Also, I forgot to add that there are a lot of free 4DTV DGII music channels on AMC 18 that I was listening to the other day on my DSR920. If you want another dimension to the 1.2m experiment, you might want to get a 4DTV receiver (either DSR920 or DSR922) and see what you can get. Last edited by electrolaw; 10-07-2009 at 03:59 AM.

Here are some photos of my installation. The pole is a 10ft piece of 2" electrical conduit that I purchased at Home Depot. I used 10 bags of concrete to secure the pole.

Can you post some pictures of your attachment to the C/Ku LNB? I am interested in where you have it attached and where the cone is attached? Is the cone attached to the very end? Is the plastic attachment closer to farther away from the dish? How much skew is optimal? Looking at electro's pics. His cone doesn't seem to be the one from Sadoun.

I fabricated my scalar rings from plans suggested here. Walrus1957 Scalar on Prime Focus Dish - Satellite TV support forum & Digital TV support forum. It took me about an hour to make it and cost about $15 total. It works really well. |

I'm going to try that scalar ring business myself...but before that, a question for electrolaw or whoever wants to answer: I'm not understanding this whole 4DTV business. For example, the Music Choice radio I wanted on Galaxy 14 is listed as DGII, but the individual channels are listed as free, so, they're encrypted but free? I don't understand the aspect of what's encrypted, what isn't, and what you subscribe to with 4DTV. It's intriguing but not $400 intriguing...yet.
Tomorrow I'll post a few pics of my setup, with big and little dishes on the same roof. Of course, the big dish isn't that big ![]() CN |

Chris,
Well, there are better explanations on other websites, but basically, DigiCipher II is a digital signal compression standard like DVB. The DCII standard was incorporated into General Instruments 4DTV receivers (DSR900, DSR920 DSR905 and one or two other ones that I can't remember). It's still used a lot on Digital Cable networks in North America. General Instruments was (I think) the only manufacturer of consumer receivers. The receivers are no longer being manufactured, but you can get one on Ebay pretty cheap. Most people prefer the DSR922 because it handles more symbol rates than the DSR920, but I've never had any problems using my 920. There are issues with these receivers needing their board batteries replaced due to the fact that they are getting pretty old by now. Google "battery replacement 4DTV" and you can get a lot of information. I replaced my battery and thought it was pretty easy, but I'm used to soldering and taking all of the necessary precautions. You can slave a 4DTV receiver to an FTA DVB receiver using the loop-out on the FTA or do the reverse and slave an FTA receiver to a 4DTV using splitters. It depends on which one you want to control the dish motor and polarity. I have my DSR920 slaved to my Ultra Viewsat and use the Ultra to move my 1.2m dish and set the polarity. if I want to see a DCII channel, I go to the appropriate sat with my Ultra, set the polarity, turn on my 4DTV and tune to the channel. Just to confuse things even more, the satellite scheme in the 4DTV receivers does not correspond exactly to what is up there now, so you have to correlate the current satellites to what the 4DTV receivers call them, like current AMC 18 is 4DTV W5. After awhile you get used to it. There are still a lot of signals (both radio and video) in DCII format. Most of them are encrypted and there are at least two programmers who offer subscription programming to C-Band dish owners who have 4DTV receivers. The two I know about are National Programming Service (NPS) and Skyvision. There are some FTA DCII channels that you do not have to subscribe to, but you still need a 4DTV receiver to get. This is the chart that I usually use to look for FTA DCII channels. http://www.skyvision.com/pages/infor.../4dtvguide.htm It's not completely up to date, but pretty close. The music channels on Galaxy-14 are FTA, but in DCII format. There are other folks who are more knowledgable and can supply the details that I left out. |

Okay, now I get it. I checked out some other sites before I posted that and they hadn't been updated in a long time, so I wasn't sure if what I was seeing was accurate or not.
Anyway...here are some photos of my set up, they're pretty self explanatory. In the picture of the two dishes on the roof, they're both looking at Galaxy 19. I included a picture of the C band mast setup in the attic to show that it isn't any big deal to set something up this way- I would prefer doing this to renting a power auger and mixing up bags of concrete! It took me about an hour to do the whole thing. Obviously, you couldn't set up a 10ft dish this way but for the 1.2m dish the house doesn't even know it's there. I also include a couple details for others on the scalar ring adjustment-note that it seems like the both Sadoun and I have ours adjusted to about the same point. There are also a couple pictures I took in Columbus at Sadoun's place showing how they had their C band dish set up; notice the spacer between the lnb holder and the arm to aim the lnb lower (I did the same thing with a sliver of wood cut on a bandsaw). As far as running the two dishes from one receiver, I'm just going to make a little switch box with a DPDT switch inside, to go from C band to Ku and back; it would be just like physically switching the cables back and forth. For safety I can just turn off the lnb power, flip the switch, turn it back on and start watching. When the lnb power comes back on, it'll send that dish to where it wants to go. And since I'm probably not going use the C band that much, I can just use Intel 9 and ISS805 for C band, and leave everything else Ku. That way there's no confusion between C band and Ku on the same sat. CN Last edited by cnagorka@gmail.com; 10-10-2009 at 01:24 PM. |

A new record!
Just out of curiosity I put in the dielectric (spelling?) plate and tried scanning in NSS806, one of the circular C band sats over the Atlantic (40.5W)...I was astonished to get 28TPS!!! The old record was 27 on Galaxy 3-C. 21 channels appeared, with several being encrypted with "Scopus", which the receiver didn't recognize as being scrambled. The channels which are viewable are coming in great, though. It's all Central and South American, except for Bloomberg Brasil, which has one channel in English (but all the video titles are in Portugese). CN |

this is my first post in this form.I hope i will learn alot from everybody here. I bought last weekend a 1.2m Fortec at Sadoun. I am still in the process of mounting the dish on the roof. But i was wondering how to install the dielectric plate on the ck1. Are you able to discribe how you did it?A picture or two would be nice. Thanks for the advice German |

German:
It's easy, just look for the little ridges cast into the body of the unit and slide the plate into them. That's it. Mine have black tape on one side, I don't think it matters which side it goes on. Just out of curiosity, I took out the polarizer plate and I was still able to receive a few channels on NSS806, but most of them went away. CN |

Dear electrolaw, Thank you very much for your wonderful info of how to slave 4DTV receiver to FTA DVB receiver, which I was looking for a very long time. Now, I know it can be done. Currently, I have Motorola 922 - 4DTV receiver, and I would like to slave it to my Coolast 6000 - FTA DVB receiver. I would like to control my 10 foot aluminum dish through independent "V Box II" dish mover and Coolsat 6000 receiver. I have also BSC 621-2 Ku/C LNBF already installed on my dish.
In your description (included below) you mentioned that you have successfully slaved your 4DTV receiver to the "loop out" of your Viewsat Ultra receiver. I will greately appreciate if you can provide me more info how did you physically connected these two receicers? I understand you connected the coaxial cable from "Loop-out" on your Viewsat Ultra receiver to your C-band LNB input on your Motorola 920 receiver? Did you connect anything to your Ku-band LNB input on your Motorola 920 receiver? Did you used any switches for passive and active voltages for your receivers so they won't get dammaged when connected together? Did you used DiSQEC switch for your Viewsat Ultra between Ku and C band LNBF or did you had only one type of LNBF installed? Thank you in advance for any help in this matter. I will greatly appreciate any answers from other members and help in this matter. Yours, Sylvester F. Quote:

Alternatively, you can use two splitters and get the same result. Sadoun, etc. sells some splitters that have one side with DC pass and one side without. The input from the appropriate LNB goes into one side of the splitter. The other side has an output that blocks DC and that side goes to the appropriate 4DTV input. The other output that passes DC goes to the FTA receiver. This allows the FTA receiver to control the dish motor and power the LNB while the 4DTV just gets the LNB signal. If you only have one receiver for both C-Band and Ku-band, I guess you could use a Diseq switch to switch back and forth between Ku and C-Band LNBF's and an A/B switch at the receiver to switch back and forth between the LNB inputs to the 4DTV, while still making certain that you still use the appropriate inline DC blocker to each 4DTV input. With my set-up, I don't really need a Diseq switch at all. I would add that there really is not much left to watch on 4DTV KU-band anyway. About the only time that I use the KU-band side of my 4DTV receiver is when there is an analog KU-band college football feed that I want to watch. Therefore, if you just used the C-Band input of the 4DTV, you wouldn't be missing much. Last edited by electrolaw; 11-02-2009 at 08:14 PM. |

Thank you very much for all your help with my two satellite receivers. I truly appreciated what you told me in this matter. For the last 3 days, I was researching your instructions and eventually managed to slave my Mororola 922 with my Coolsat 5000 FTA receiver. Now both receivers work together. Currently, my Coolsat 5000 controls big 10-foot dish movement, and also provides signal to my slave receiver which is Motorola 922. How did I connected them? From my Coolsat 5000 “loop-out” at the back I attached my new 2x1 Diseq input. From its two outputs, I connected one to my Motorola 922 C-Band LNB input and my second Diseq output to the Ku-Band LNB of the 4DTV receiver. Also on each input of my 4DTV receiver I installed inline DC blocker as you recommended. Without DC blocker my dish mover didn't work at all, and the whole system was freezing and was not responsive to any changes which I try to make with my Coolsat 5000 receiver. I noticed that in other to watch some free programs on my 4DTV my Coolsat 5000 must be turned ON and if is set to horizontally polarized transporter then all horizontally polarized channels are also available on 4DTV receiver, but no vertically polarized channels are available on 4DTV receiver at that time. To have them back I have to set up my FTA receiver to any channels which are vertically polarized and then Motorola 922 will pick up all vertically polarized channels. I should mention that in our area there is no one who is using 4DTV receivers anymore, and could help me with some questions I had. I was told that this is obsolete equipment and I am only wasting my time. I get this receiver from a gentleman who sold me other satellite equipment and he didn’t want to keep it anymore. I should say that: there are still lots of work to do with my current system. Now, I planning to find channels which I can pick up clear with my Motorola 922 receiver. So far, I found some on satellite G1 and they are: # 5, 11, 12 and 17. Also, on G4 I can pick up channels 16 and 17 without any problems. However, I didn’t have more time to search for more - today. It took me some time to find my DC blockers. Do you thing you might have some info about other satellites channels which I can currently pick up for free? Please let me know when free. Make a short list or so. Also do you know how to turn off “Dish Limits Option” on my Motorola 922 receiver. Each time I try to enter a different satellite then a big message on my TV shows: “ This satellite is out of limits”. Press Go back. Then another screen shows me Limits: Dish position 5000 (1. East limit 5000) (2. West limit 5000) but when I try to change its values it won’t let me to change unless I enter 5000 for both. So each time I try to enter or change to a new satellite, I have re-start from the beginning. I have to re-program them all over again. Thank you again for your time for reading my response and all help. Have a great weekend. Yours, sylvek |
