    Can someone explain to me what spot beams are? Perhaps a web site with some info? Is this why we need elaborate switches and multiple LNBF's in order to have multiple receivers? TIA

    As to the spot beams....There is a very good page showing where each spot beam is here http://www.stratuswave.net/~bryan27/dbsbeam.html
    The satellites that have been used up to now only use a ConUS beam (Continental US). This means that if they transmit a channel, the entire country sees it. A spot beam allows a satellite to send a channel to a specific point of the U.S. This allows the same frequency to be reused several times throught the country. The only limiting factors are uplink channels, how many transponders a satellite can carry and how tight the beams can be made and still cover a desired area. This allows many more channels to be carried on the satellite. The down side is that no matter how big a dish you have you can never ever get a channel if it is on a spot beam pointed somewhere you're not.

    As to the LNB and switch situation....No. Spot beams are not the reason for the switches.

    Each satellite slot transmits up to 32 "channels" (Transponders). On DBS satellites 16 are polarized clockwise and 16 counterclockwise. This is to prevent adjacent channel interferance. An LNB can only receive one set at a time. The receiver tells the LNB which one it needs depending on what program you selected. If you have more than one receiver you can't just split the line coming from the LNB to the receiver because if the second receiver wants to get one polarization and the other wants to get the other polarization then the LNB gets conflicting instuctions. One of the receivers will not work or worse, you'll fly the LNB (unlikely). A dual LNB (or two LNBs in one housing) is needed.

    With Dish a Dish 500 receives two different satellite slots at the same time. This complicates things. Now you have two satellite signals on the same frequencies and the same polarizations. A switch is needed to be able to separate the two. Two LNBs are needed. One for each satellite slot. The switch then activates the correct LNB on the correct polarization depending on the program you choose on your receiver. If you have more than one receiver, you need two dual LNBs and two switches.

    Dish simplified things a little by developing the "Twin" LNB which is essentially two dual LNBs and Two switches in a single housing with outputs for your two receivers.

    If you have more than two receivers, this complicates things even further. A different switching system is now required if you don't want to add another dish! Esssntially, the 4x4 switch allows up to 4 receivers to see all four possible combinations on two dual LNBs. What the switch does is "freeze" each half of the dual LNBs on one of the polarizations. The switch then takes the command from the receiver directing the needed signal from whichever LNB/polarization is needed. Each receiver can then work independently. Again Dish came up with a user friendly option by coming up with a "Quad" LNB. Electronically, it's the same as two Dual LNBs with an SW44 switch built in to one housing.

    And if you want to see one of the side satellites (61.5°, 129°--Philly only--, or 148°) you then have the same deal again! An SW64 does the same thing as the SW44 except for the additional dual LNB. The "Twin" and "Quad" LNBs allow you to use a cascading switch solution. It's cheaper, but limits the side slot to two receivers unless you use more than 1 additional dish.

    Take a look at the EKB at http://echostar.swiki.net for more info. Also the DBSTalk home page has lots of links to techie stuff.

    Hope this helps.

    See ya

    DBSOgre, The first I heard of WPB was yesterday when someone told me about it and I verified it on the EPG data. Other than Grand Rapids and West Palm nothing else has suddenly appeared. E* promised that Honolulu and Anchorage would be added first (so much for E*'s promises).

    Tony, I wondered what happened to CBS and thought it was a typo till I saw that it wasn't in the EPG data. I agree probably WTCE(TBN) independantly owned, WFGC(CTN) they have demanded all CTN stations in an LIL be carried, and WPPB(EDU) will be on 61.5.

    Tony, thanks for the info! It answered my questions! I'm a geek at heart, so I always want to know how everything works. That's what happens when you have an engineer for a father. :)

    The Anchorage/Alaska spot is back up - again a strong signal 300 miles SW of Anchorage. (117/125 on 6' dish).

    This is GREAT news, not only for television viewing, but for the business situation here. Now to complete the story they still have to add CBS, although in my area my customers can get CBS with a waiver with no problem. There is a dealer chat today at noon so hopefully a timetable for activation will be announced.

    I am about 20 miles south of the north end of the WPB DMA and the TP3 spot here is about 15 points hotter than other transponders. The next DMA north of here is Orlando, which I assume is on a different spot.

    Orlando and Tampa haven't been moved to spots. TP1 could still be activated for South Florida. The TP1&3 beam covers Tampa, Orlando, Miami, and West Palm.

    Bryan,

    I've learned that WTVI (8656) and WNSC (8661) in the Charlotte DMA have moved from 61.5 to 119. I'm thinking they're on TP7s14, could you confirm?

    See ya

    Tony, just when we think they are done moving channels they move more :)

    WTVI(8656) TP5
    WNSC(8661) TP5
    WTLJ(8720) TP7
    KBYU(8540) TP9
    KULC(8541) TP9
    KTMW(8542) TP9

    I'll update the chart on page 1 to reflect these changes.

    I checked this morning, and no change in Sacramento. 1 is still CONUS, 3 has no signal, 5 has no signal but is to serve sacramento, 7 is full bore 125 (only once have I seen it drop to 122), and 9 is no signal.

    Bryan...Looks like K.C. may be next! I just confirmed that KMCI moved from 148 to 119. But I don't know what transponder. Could it be starting the K.C. locals on a spot? TP 9?

    See ya

    Tony, KMCI is on TP3 so now we know that the KC beam is 1&3 and the Mexico City beam is TP9. E* kept changing these two beam TPs around. At first KC was 9, then it was 1&3, then back to 9, and now it is 1&3 with 3 activated. I guess E* finally made up it's mind :)

    Looks like this spot needs the three transponders it'll get. Topeka, Okrahoma City, Tulsa and maybe even Omaha and Lincoln could be served from there. I found it funny that E*7 would only use one tp in that area.

    Thanks.

    See ya

    Bryan -

    It might be jumping the gun a bit but do you know what the plans are for the Southern California spot on E8? From your map it looks like they could add cities like Bakersfield, Palm Springs, or Yuma. They could go the other way, though, and put the rest of the LA channels currently on 148 over there. Any thoughts?

    That's a good question. Since TP1 will be activated around June 16th (this is the date that some channels are moving from 119 to 110) most likely those TP1s will have the side sat locals moved to them and any new cities would be added to the spots on 110. There are 25 channels for LA and SD on the spots. E* will probably completly fill TP1&3 at 119 and then put 1 channel on 110. So there would be plenty of room to add Bakersfield and Santa Barbara to the 1 TP beam on 110.

    I would say that Santa Barbara would be added before Bakersfield because several LA stations have Low Power Translators in the Santa Barbara area.

    219 HSN2
    224 SAH
    402 GOLF2

    These channels appeared on the guide this afternoon.(WELL, SAH is still at its old location but displays "Call xxxx" message) They have the message of "Call xxxx to request Dish". But these are the only ones that are showing the message. Ch 101,103, 226,9601 doesn't have the message. I wonder if they decided to only move the channels above instead of the original 10?

    ch 222 & ch 401 no longer appear on the guide. If these channels appear on your guide they are probably coming off from 110W.

    I bet they'll get moved next week. They needed to stagger the move to prevent a "mad rush" :)

    Sacramento locals may be moving tonight. According to the on-air guide, here are the off-air times:

    8630 (ABC/KXTV) - 12:05-1:05
    8631 (CBS/KOVR) - midnight-1 AM
    8632 (NBC/KCRA) - 11:35-1:35 AM
    8633 (FOX/KTXL) - midnight-1 AM
    8634 (WB/KQCA) - midnight-1 AM
    8635 (UPN/KMAX) - midnight-1 AM
    8636 (PBS/KVIE) - 11-1 AM
    8638 (Univision/KUVS) - 11:15-1:30 AM

    However, only spot 7 is still illuminated, and is serving the SF Locals. KVIE has a TERRIBLE signal tonight. Hmmmm..... new feed?

    Thanks Bryan - I had forgotten all about Santa Barbara. That's a weird one too with KSBY (NBC) to the far north, KCOY (CBS) to the northeast, and KEYT (ABC) in Santa Barbara proper. They make extensive use of translators throughout the region since it is almost impossible to receive KCOY or KSBY from downtown SBA.

    Has there been any progress on the "significantly viewed" issue? KEYT is virtually the sole source of local TV news for Ventura county but would not be available to them via DBS under current rules since they are technically in the LA DMA. They would have to rely on the KEY news rebroadcast on KADY.
