Does anybody know or heard of what DVB-HDU is? Another thing, Iceberg, I don't mind generally but it would definitely help if the *original* thread had at least as helpful title than the one just closed. Thanks for the pointer though.

Cool! What is DVB-HDU?

Myles, Do you have any idea what satellite and band they are using? I mean the RTN promotion... Oh, yeah and how much is the receiver? Thanks!

I asked this question before but didn't get a definite anwer... Is it possible to control a receiver from a PC? If so, the PC (slaved to the receiver) could just send a command (via serial?) to the receiver to switch to a particular sat/polarity...

'SATELITE SYSTEM UP AND RUNNING FOR PENNYS ON THE DOLLAR' Anyone interested? Worldwide shipping... :yes

You're welcome. Good luck!

If I remember correctly, there are 4 uncommitted bits that diseqc X.1 can use. Mode 1,2, and 3 allows you to pick a pair bits that your receiver will use to switch the inputs (1- bits 1 and 2, 2- 2,3, 3-3,4, if I'm not mistaken). In theory it is possible to build 64-head configuration using 5...

This is simply not true. Without LNB (but with arms) the dish registers at about 14 kg, which is less than 31 lbs. Standard Az/El mout is about 5 kg (11 lbs) more, and there are custom solutions that could reduce the mount's weight.

OK, thanks spider, I guess that wheel is attached to a worm screw or something like it... Another question, did C-band performance changed at all when you cut the scaller to attach those Ku LNBs?

Well, this question is not directly related to this thread. I'm talking about this photo. I assume you use adjusted angles when you position your dish, right?

:shocked Wow!!!! :shocked What a setup, man! You are my hero! Do you mind me asking what are you using the elvevation servo for? I'd also be interested if you post some comparison between you feedhord-mounted Ku LNB vs. the Invacom. Great job! :yes

Do you mind me asking what is the difference?

I have 5 Ku LNBs (1 linear and 4 circular) on a stationary DirecWay 24x36 eliptical dish. I could post a picture but Iceberg himself will put me in jail if I do. :cool:

That's exactly what I meant to say... I'm definitely not a trained expert in high-frequency radio wave design but my basic understanding is that performance of such devices is extremely dependent on their shape, which, in turn, depends on the wave length. This makes designing something...

... or get a spare old-style scaler-free LNB-- you know, the one with the starndard flange tha is meant to be screwed onto the feedhorn. Personally though, I don't believe in this concept. It may or may not work for prime-focus BUDs, where this contraption is located in the shade of the...

Thanks for your reply, Cascade! No I'm not going to capture stream-- I can easily do that with my PCI card. What I (ideally) need is to be able to tell the receiver what to scan and then download the results. Now, I've heard of the gtools that can supposedly do the latter (BTW, I have yet to...

Ahem... :rolleyes:

caddata, Sorry, I was so pissed off to find my error I didn't notice your success report. Congratulations! When you design a multifeed it actually makes a lot of sense to play with the off-center LNB placement once you think you've put it in theoretically perfect spot. You can learn a lot...

Yes, caddata you are right my calculations were wrong-- the area is NOT negligible. However, I doubt you should treat treat it as totally lost reflection area. Its contribution may be reduced thanks to suboptimal scalar but hardly by 100%-- this is unfortunatelly only my speculation.

Dish gain is proportional to its surface area. The difference difference between 36" and 33" is about one sixth of a percent. Is it worth it to be concerned about? Speaking about dual feed, oh yeah, it will be very practical. I'm also contemplating my next C/Ku project (I've got a spare CM...

With all due respect diseqc can be used in series. In theory even regular 2.0 swicthes can. The only problem is the receiver's software that has to be be smart enough to assign different adresses to the 2 switches on power-up and later on address them individually. So far I have yet to see or...

Ahem... It's probably not my business but just as a suggestion. Why don't you ask Stefan to sell you an extra one he had because of the seller's mistake. He's not using either anyway. :rolleyes: caddata, Are you taking into account the fact that the dish is actually elliptical itself? I...

Hi everyone! Does anybody know if it's possible to control a receiver from a computer. What I basically think about is allowing some script to scan certain sats then download the results and then process is somehow (for instance, have my SS1 tune to each usable channel and take a snapshot of...

What the heck is this? Originally found here. Sorry for the ALL CAPS-- that was the original description. NEW, CREATED FOR INSTALLATION ON CHAPARREL STYLE C-BAND FEEDHORNS BACK IN THE DAY, ONCE MOUNTED ON THE EXISTING FEEDHORN WITH THE SUPPLIED STAINLESS STEEL CLAMP THIS ADAPTER IS...
