I just bought a C-Band receiver - good deal?

Larry,

For analog feeds, you are looking for the Grey bar that shows "NTSC". NTSC is analog while "DVB" is a digital dvb signal that your normal FTA receivers can get

THANKS! Will check it out.

 

[iafirebuff]

OK, on SBS 6 I see listed several NTSC Ku feeds. I see what you mean THANKS! I got busy with another project and have not swapped out lnbs yet. I have a universal on my motorized at the moment. Another thought, my 30w dish has a universal on it too, and I am using a Diseqc switch, so if I remember, you can't ue universals with Diseqc switchs, correct?

 

[iafirebuff]

Just looking at the instructions - I go from the Fortec to the IF input on the analog? It says it supplies power to the lnb. Will this do anything to the Fortec or the motor (adverse)? TIA!

 

[Mr Tony]

go from the loop out of the fortec to the if in on the analog

it wont touch anything on the motor because the older C/KU units used ribbon cable to run the polorotor (the motor on a C-band dish)

 

[iafirebuff]

Got it! THANKS! It looks like I can just run the 75ohm coax out to an open rf input on my tv, and leave the fortec hooked up the way it is already. I might have to go swap that lnb out tonight

DiSEqC switch will work with a universal, just can't use an external 22k switch since the LNBF already has a 22k switch to go from low band to high

 

[iafirebuff]

I meant to say a standard - I thought you could not use a standard lnb with a diseqc switch.

Standard works fine with a diseqc switches. I don't have any universals, but I have standards and have diseqc's, 22k's, & multiswitches mixed throughout without a problem.

 

[iafirebuff]

THats good to know! I can't remember what now, but I thought you could not use universal and standards together....maybe it was when I was combining a Dish LNB with a Standard using a 22k switch. Boy, I must be getting old.

 

[Mr Tony]

Universals can't work with a 22k switch...they can work with multiswitches (3x4, 3x8, etc) and diseqcs

Standards can work with all of them (22k, multiswitches, diseqcs)

 

[Mr Tony]

you can mix universal LNB's and standards....just the rule of thumb I use is
Universal LNB's and anything with a 22k switch do not work together

Standard LNB's can play with any switches out there

My daughter just called me from home and informed me my new c-band receiver showed up! So, now to swap out the univ lnb for a standard and hook up the new receiver! I assume I just run a jumper from my Fortec to the lnb input on the analog receiver? Anything else I need to know? I am anxious to try this out!

Depends on the capabilities of the C Band receiver . Some of the newer ones had the capability of 13 / 18 volt polarity switching . If it does , you can use it as the master & the DVB-S receiver as the slave .

Which ever is master , it will be the one that controls polarity .

make sure your fortec is on a H pol if you are slaving off it

What channel is that , I never found much on analog Ku except wild feeds , from time to time ?

Let me think about this . If you are all wrong , please forgive me . And correct me .

If you have the DVB-S receiver connected to the universal Ku LNBF , then what comes out of the DVB-S receiver loop through " F " connector is IF frequancy signal ?

If memory serves , the LOF 1 of a Universal LNBF is 950,000 ? What is the band width of LOF 1 ? What is the band with oof the Analog receiver ? 950,000 to 2,000,000 , more or less ?

If he can set the LOF of the analog receiver , is there a posability it would work , with maybe the TP's / Channels being numbered wrong ?

And , if needed , he could set the DVB-S receiver to a high TP to catch the LOF 2 band width ?

Buy a sat rated spliyyer that passed DC on one port and blocks DC on the other ports . Hook the LNBF coax to the in , the out that passed DC to the Forted and the analog to the other out .

just a test card that says "Echostar" and lists a number for reserving transponder space

sort of. The issue is the LNB LO on a Universal is 10600 whereas a standard is 10750. Most older recievers go by a IF frequency, which is between 950 to approx 1600...So you add the IF frequency to the LNB LO and that is the frequencies we all know

So here is where the problem lies....there is a 150mhz differwence between Universal & Standard LNB's. So channel 1, which is 11720 is 970 IF frequency on a standard LNB...now take 970 and add to 10600 and you get...11570. So to get channel 1 with a Universal would be on channel 8.(each channel is 20k steps so just add 7 1/2 to each channel...)..so that's fine..until you get to 18..which on a standard is 12080 ffrequency...add 150 and you are above 12200 and most analog boxes can't go past 12200 (I know my Toshiba & HTS units can't)

So it WILL work with a Universal LNB but only up to channel 17

Could you use the Fortec to kick the universal LNBF into the upper range ? Would that help ?

I have a little analog Chinese receiver that I think goes from 950 to 2000 something . Do not know about what he bought ?
