G-18 seems really hard to find. I occured to me that it may be too far down on the horizon for me to point a dish at. Has anyone else run into this? I'm trying to find the research channel on KU. Any thoughts, ideas, or suggestions?
 
My 1.3 meter channel master dish is pointed in the right direction, right down on the horizon. shooting thru lots of pine trees and buildings. I'm thinking I may need to get the thing further up into the air.
 
Elevation to the 123° bird from Mobile Alabama is 38°, with 44° skew.
I don't consider that right down on the deck.

You might try the soda straw inclinometer, and see if you can get a clear view between buildings or over trees, and try again.
Because they -will- take out your reception!

- Delta Charlie had some variation on the idea, too

There is a new iphone app called dishpointer LOS.

You tilt your phone until you have it showing the correct angle then snap a picture.
The picture will show you if you have a clear line of sight.

I found it to be very educational because I didn't understand how the line of sight thing works too well. This new app really is very useful to me, being that I'm still very much a newbie in all this stuff.

A small laser level used with an inclinometer or anything that measures angles - I have used a speed square - will work when it is starting to get dark. Just look to see if the laser dot hits anything that might be in the way.

Don't forget that offset dishes (assuming that's what you have) point about 25 deg (+/- 5) higher than the appear to be pointing. In general, you can't point an offset dish at the horizon unless you've modified the mount.
 
Thanks guys. Guess I'll continue my days up and down, back and forth. I know it's there somewhere, but i'm starting to doupt. Sathawk can't find it. Neither can a spectrum analyzer. Been on this for weeks now.
 
Have you set the skew on your lnbf? (you didnt mention a motor, so I'm assuming you are using a fixed dish).
Skew has to be fairly close to get a signal on digital channels. Standing behind the dish, the skew will be 'clockwise' from the zero position. Check the aiming sites for the proper skew, for me its in the 20-30 range I think, I have a direcway dish pointed at 123 right now.
 
Try popping a circular LNB on and find 129w and 119w. Set the LNB freq to 12200... It will be right between them
-------------------------------------------------------------------------------------------------------------------------

There are a bunch of other questions that could help:

What LNB are you using?

What frequency is your LNB set up at? (muy importante)

Have you manually entered a strong transponder frequency (TP) and sample rate (SR)?

Sorry for being so pedestrian but I'm new also. I have had these problems recently.

the LNB freq is 11250 for DBS
 
they're gone
all were sold to either conglomerates like Daystar or local buyers who already have them up and running already without satellite presence
 
GOOD NEWS! I found it! That is to say some V feeds on G-18. Still can't find the Research channel on horizonal. The SR and FEC is what is listed in Lyngsat. What are you guys useing?
I'm useing a Comsat dish, looks about 15 ft. steered with a reasearch Concepts RC1500, Dues feedhors for H & V for both C & KU. I still can rotate the polarity to null out H & V. I'm trying to make a Tanburg 1221 ird work. also a Standard omni Agile MT630 for NTSC. DVB is a new beast to me.
My next challenge is to find G-18 on a fixed 1.3 meter channelmaster dish. Oh boy!
You guys are the greatest! I really appreciate the hel[p.
 
you da man

Iceberg. You are the man! SR is listed as 1 on Lyngsat. 4580 is the correct. How did you find that?
Thanks again for your help.:)
 
I usually use our own thelist ;)

But for Lyngsat, where there is more than one channel in a mux, the top shows the symbol rate (and the FEC but most receivers that is automatic)....see attached

Today I actually moved the dish, and not penitrating roof mount over about 50 feet, I could be shooting thru some trees, buildings, and obstuctions that I should be clear of now. I'm using a Norsat KU LNB 11.7-12.2 gig. LO is 10.75. NF is 0.8db. I've dithered back and forth with the polarity. I'm on top of a 3rd story building. It's got to happen soon.
Now I'm looking at Lyngsat, on G-18. The Research channel is gone! Another strong transponder, it was Peace TVat 11965, GONE. What's up with that?
