Using BSC621-2 C/Ku LNBF

[vj9999]

I think TSReader only shows errors it cannot recover from.

Rod might give you the right answer over on satforums.

You can see on a spectrum analyzer that the signal is there. Here is a snapshot of horizontal on G3C.

Hi VJ
I'm curious what spectrum analyzer gave that trace, and did it come from a 4' dish? I've always wanted to get a real spectrum analyzer, but except for speed, I'm really happy with the traces I get using the unmodified Broadlogic card, using Hans' blscan program plus my display program. Ie I get the following:



comparing that to your trace, I was having a little problem recognizing peaks from one trace to the other, but I think that is because your trace started below 3700, on the other hand, I'm not sure what it's picking up down there???

But anyway, what spectrum analyzer did you use, and what size dish did it come from???

[vj9999]

My trace came from BLSA (http://www.moonglow.net/tvro/blsa.html) .

It did come from a 120cm offset dish. I'm not suprised that you don't recognize some peaks since they are most likely strong signals from surrounding sats. Exactly why 120cm is just for hobby and not the ideal solution for c-band

OK, THANKS.

Hi,

The LNBF holder on the 120 cm dish, does it have to be alter in any way to support the LNBF? What exactly do they mean by locatio.....location? I live in south Florida, what kind of location would that be?

Jose

[rainman]

south Florida should be great location for fta.

[pr1947]

Now that I know a have a decent location, where do I get the LNBF form since Sadoun does not sells them?

Please be aware that a 4 foot dish and Cband is a very compromised system.
You will only be able to pick up the very strong Cband signals.

Please go to www.lyngsat.com, and pick out some of what you think you would like to receive on Cband, and I (and others here) can tell you if it will come in or not on a 4foot dish.

Unless you like Christian broadcasting, there isn't much more than that with small Cband dish.

One of these days I'll map out what I'm getting on Cband and post here...

[Jose47]

Thanks for the advice. I do not have much a choice. Big dish is out of the question. I'm looking at it this way whatever one C-band signal is better than no signal at all.

Jose

[pmb1010]

OK with that said, you can get a 120cm dish, HH120 motor, C/Ku band lnbf, and the LNBHOLDER3, and a Lifetime Classic and have at it.

It will get you some Ku and C band digital signals. Stuff that's strong on C band is Canada weather channel, some WB stations, a few church channels.

It will be expensive - expect to spend about $600 on this setup.

I guess the bottom line is what do you expect to get out of your system?

[pr1947]

Let me see if I understand what you mean by a few Ku and C band digital signals. Are you saying I will loose some of the Ku channels I'm get now because of this system? I have a motorize Cm Ku dish with a Fortec 0.3 LNBF and my Ku reception is great. I do not want to mess up what I'm getting right now. The idea about adding C band to my system ( I know a have to get a Cm dish) is to have other frequencies to tweak with. This is my hobby and enjoy doing it. Once again, I appreciate all of the inputs I get from you guys.

Jose

[pmb1010]

I cant say for sure if I lost some Ku band signals.
I know the Ku reception on the combo is lower than my Invacom on the smaller dish.

I'm getting everything that I used to get, as far as I know. I did try for some football feeds over the weekend, and the signal was at the low limit and I did not get it. I cannot say if the 30" and the invacom would have gotten the signal...

So even though the dish is much bigger, I think this combo LNBF is a compromise.
If I had the chance to "do it over", and I had the room (which I dont), I'd put in 6' C band dish with C band only LNBF, and a separate 90cm motor Ku dish.

[pr1947]

That is also my problem. I just do not have the space. Then again I have to give it a try and see what happen with the BSC621-2 and 120cm Dish. I was planning on upgrading my system anyways. All I stand to loose is $50.00 worth of LNBF. Once I get it up and running I will let you guys know.

Just some findings. I finally got mine dialed in on 40.5 for circular C Band reception. I am using a 8.5' mesh dish. I found the lnbf does need to be skewed even for circular reception and when skewed for peak signal on a strong tp I am receiving both L and R signals. I also peaked within the scalar ring once dialed in on the target sat. I do not know how this would work on a steerable dish. Mine was a fixed project for 40.5 only.

Signal strengths are across the board with some being in the 90's and some at threshhold for me (25). I have not tried yet but am guessing that switching the plate would change this. I also imagine that I could peak skew with the plate installed and dial in just one or the other (L or R).

Ran a blind scan and came back with 99 channels in the clear. Once I have comlpeted the install I will run a complete scan and manually sift through the channels for any listed as encrypted that are actually clear.

So far very happy with performance of this lnbf BUT I am only using for circular C Band reception. Not as a combo unit.

cool thanks Sadoun great addition.

[pmb1010]

I finally bought an old C band receiver from Ebay (General Instruments i610 receiver). [Bill, now I have a remote!!!]

Using the 621 Combo LNB and the 120cm dish, and have been scanning for open analog C band signals.
I have been having some good and mediocre results to report on C band analog. Some stations come in big time, a few feeds here and there from Fox, ABC (good morning america came in GREAT), Buena Vista feeds (tony Danza show was on).

When I had the borrowed receiver I have (no remote), it was stuck on Ku band. I did get the test card with it, but with this new(er) receiver it came in quite nicely.

Would I use this as a "production" setup - no way. The signals are not strong enough. I cannot see G10R where all the movie stuff is, but from what I've read - it's tough to get those even with an appropriately sized dish. For the hobbiest, it can be fun looking for the odd signal here and there.

Follow up question for Fortec users - there is an "antenna in" port on the back of the receiver, for antenna or cable input.
Right now I have the loop out port going to my C band receiver, and it's hooked to a 2nd tv so I can set the Ultra on V or H as needed, and watch C band on 2nd tv.

I'd like to eliminate that 2nd Tv, and reroute the signal from the cband receiver, into the Ultra so it flows via S-video to my regular TV. But I cant figure out how to switch the Ultra feed to anything other than the satellite input. If i turn the Ultra off, I lose capability to change V or H that goes out to the c band receiver.
Anybody know the answer to that one?

[rainman]

pmb1010 if you like c band wild feeds check IA6 they have alot of feeds off and on. as for hooking it all to one TV I use a AV selector so i can see all my receivers on one TV.

[elgemcdlf]

Check Sadoun's slaving diagrams for a 4DTV receiver and reverse the mentality since you are controlling the lnbf from the DVB receiver and not the 4DTV receiver. I know your receiver is not 4DTV but the concept is the same.

[pmb1010]

elgemcdlf,

you missed my point.
I have the setup working. WHat I wanted to do, was pass the video signal thru the ultra so I can switch back & forth so I can see both the Ultra setup screen, and the C band reciever's screen. Really need to see both at the same time to make things easy to operate...

Actually, I solved the problem by routing the C band via RG-6 video cable to the tuner on my monitor (and CH3 input) and use S-video on the fortec to the monitor.

Still a pain, as I now have 3 remotes to juggle to change things around.
WHat I now ended up doing was put a small 3" tv on the Ultra's Video out RCA jack, now I can adjust V/H and dish position and watch the C band on the bigger monitor screen.

Do not think I missed it. If you reverse slave as per the diagrams you can use the TV/SAT button on the remote allowing you to quickly switch back and forth. On your C Band receiver the button may be called source.

[pmb1010]

I guess I'm just not seeing what you guys are trying to tell me.

Some one needs to draw me the picture, using the Ultra as the master.
And, the Ultra has S-video going to the TV monitor. I'd like to retain that connection, as the Ultra also outputs AC-3 to a decoder I am using.

[rainman]

how many ports do your tv have.

I know this is extra hardware, but I have one of those RS 4 input A/V switches. I have C-band, Fortec Ultra, DCII , and Fortec Lifetime going into the 4 inputs, and can switch between them via one keystroke. You can choose any key on any remote to switch you to the input you want.

It works pretty well, except that I chose the wrong key for my fortecs. Ie I chose the "Exit" key, which means if I'm in the antenna tuning section, and want to go back to C-band to do something, then to get back to Fortec, I have to hit Exit, which takes me out of the antenna section. So I need to choose another key, perhaps volume or something, that won't take me out of a menu.

[elgemcdlf]

Ok Split your lines coming in from the lnbf. You need to bring both lines in and bypass the internal DiSeqC. Now one leg of each split goes to the 2 inputs on the analog receiver. The other 2 go into a DiSeqC switch and on to the DVB receiver. Now the output of the analog receiver goes to the Antenea in on the DVB receiver. Need to run DC Pass on one leg of the splitters and that leg should be for the DVB receiver.. Now if I did this right you should be able to watch TV utilizing the SVideo out to the TV from the DVB receiver and when you hit the ANT/SAT button your analog receiver should be showing on the screen. Hit the button again and the DVB receiver is showing.

You might dig around a bit. Perhaps your analog receiver is capable of handling lnbf's
