my first C-Band set up, need tips (Intelsat 9)

[vixens]

I have a the following hardware I would like to set up for Intelsat 9 @55 Degrees (location Belize, Central America):

* Sadoun 6 foot prime focus, solid
* A BCS 621 KU/C-Band Lnb

* A Lexium DBS7000 C/Ku Sat receiver



I have never done a C band set up, only KU FTA with off set dishes.
Can anyone give me some guidelines ?

Q: is it linear ?
Q: the sat dish's manual does not indicate a focal point (the distance between center and focal point) Any idea ?
Q: is it measured from center to the tip of the feedhorn ?
Q: Search for signal: better with the signal meter or via the signal indicator on the receiver ?
Q: the receiver does not have Intelsat 9 preset; I added it (the name) manually but naturally there are now no transponders which i guess can be added once the signal is locked. Any advise on that ?

Q: receiver/sat set-up:
LNB type ?: standard, Universal, User
22K?: on or off
Polarity: H/V (I assume)

Thanks in advance,
Wolfgang

Q: is it linear ?
A According to what lyngsat says, both are linear.
Q: the sat dish's manual does not indicate a focal point (the distance between center and focal point) Any idea ?
A. It can be calculated.

But I bet, the arms are at the correct length. Minor feed tweaking should be all that's left to do. Even the calculated is not perfect.
Q: is it measured from center to the tip of the feedhorn ?
A. from the bottom dead center of the dish, the focal point is usually a 1/4 inch inside the feed throat.
Q: Search for signal: better with the signal meter or via the signal indicator on the receiver ?
A. Either work fairly well, although a meter is more convenient. No taking a TV and receiver out to the dish.
Q: the receiver does not have Intelsat 9 preset; I added it (the name) manually but naturally there are now no transponders which i guess can be added once the signal is locked. Any advise on that ?
A. You must also enter an active transponder in the receiver, or meter, to lock on to, to get a Quality reading. THEN you can scan in other operational transponders.
Q: receiver/sat set-up: LNB type ?: standard, Universal, User 22K?: on or off Polarity: H/V (I assume)
A. BSC621 (NOT the BSC621-2) needs receiver programmed, for C Band reception. TYPE:Standard, L.O. 5150, 22Khz off.
For Ku: TYPE: Standard, L.O. 10750, 22Khz ON.
BSC621-2 uses DISEQC switch for band. 1 for C Band, 2 for Ku. Also change Ku LNB TYPE to Universal. L.O. should be 9750/10600 and AUTO 22Khz. (L.O and 22Khz may be set automatically with Universal selected)
(The above assumes the jumper is used as shown in it's instructions)

Great, this is more that I was hoping for . . .thanks !

Q: the lnb/feedhorn is a BSC621-2 C/Ku
Q: ref. A. You must also enter an active transponder in the receiver, or meter, to lock on to, to get a Quality reading. THEN you can scan in other operational transponders.

I played a few hours to get familiar with the receiver . . . I am not sure how to add transponders.
What would be a strong transponder I should add for an initial search ?


Thanks, Wolfgang

A straight c band lnbf will give you better performance on c band than a dual band lnbf

Kinda confused yet as to which satellite you're looking for

or

Transponders:
I-9 @ 58W - 3840 Horiz, SR 27690 or 4040 Horiz, SR 26590
I-805 @ 55.5W - 3695 Vert, SR 8888 or 3768 H 4427
BTW: I am also not sure how to add transponders into that receiver, no experience with that model. Also, I agree with Truckracer, a single band LNBF will perform better. The dual band types are a bit of a trade-off performance wise. Many have tuned them up on the primary band of interest and 'take what ya get' on the other band.
