Q drops to zero on mini bud @99°

[jogon64]

Hi, this is my first post though I have been reading and learning a lot here for a few months now. I set up a 1 m. mini bud with a bsc421 + scalar ring and had my first C band experience. I´ve had a bit more experience with ku as I am currently watching 30,79,97,101,116, and have at times tuned in to 58,93,123,125. I´m currently aiming at 99 trying to watch the networks mux from puerto rico,. I usually get a Q between 45 and 59 it does vary during the day, but it takes a dip to zero every now and then and my picture freezes. This keeps happening all the time ever since I started testing c band. I aimed my dish todat at 58 and 116 withe the same outcome. Could it be the lnb? It´s the only one I have now. Is 1 m too small? Lyngsat says I need 0.8 m. I´m testing with the same results on Pansat 2500, Pansat 2700 and Coolsat 5000. Any advice would be welcome as I don´t know if I´m doing something wrong. Thanks! (This is the best site for learning!)

I assume that your 1m dish is offset feed?

Are you using a conical scalar ring?

Lyngsat is sometimes optimistic.

 

[jogon64]

My dish is offset and yes I´m using a conical ring.

sometimes?

yeah take those maps with a huge grain of salt. I've seen some of those maps saying I can get C-Band on a 30" dish when I can barely pull it in on the 6 footer

 

[Mr Tony]

Is 1 m too small?

yes.

1.2 is usually the minimum for stability but a 6 footer (if you can do that) would be the best

I don't know if he's done better than anyone else with a 1m Primestar (I lost interest), but a while back, Linuxman made a good effort.
I know him, and he would have tuned 'till his fingers bleed, to get the best possible out of his setup.
See at least the link to his list of receivable signals:

For a pretty good example of what a 1.2m will do, ya might check out PopCorn's thread.
He did about everything I can think of to make it work:

I didn't double check, but I'm sure both reported their reception success on 99° west, for networks.

My internet was down this morning but I finally read those links suggested by anole, they really did help. Thanks Ice too for your help. Truth is a mini bud is really just for testing, you can´t get serious reliable cband on it. For now the 1m is all I have. I´might be able to get a 1.5m offset that someone told me about, I´ll have to look into that next week, not sure my wife would be happy with the idea though. I do already have six 30" ...... I was just thinking... if I did get the 1.5m how many ku lnbs could I mount on it? Say i aimed it at 99° how far E and W could I go on some custom multiple bracket? I wonder if that would sound convincing to the wife? Any thoughts? Thanks!

thoughts? yes:

This thread is pretty long, so just scan through it looking for tables and pictures:
Linuxman and entire arc on 6' Prodelin:

Mike of Global-CM, has a similar 6' dish which claims a wider span of birds.
See his site and look for a post by him here on the forum, for more info on his Skyvision creation.
Think it's the same dish Fred used, and only a little larger than the one you propose.
