    Live Olympics?

    The Canadian coverage claims to show every event live, although some of that is streamed. Probably all their feeds on FTA birds are encrypted, but if you subscribed to Shaw or Bell, it would all be there. The kids were up at 3:30 am watching the opening ceremony.

    T90 Toroidal Dish?

    I would read the whole thread that KE4EST linked. A few of us are quite discerning and have gone to the trouble of properly aligning a T90. Two of us made some very detailed measurements, and over about the center 20-25 degrees they will outperform a 90 cm offset. A have three T90s, and they...

    Requesting help for installing a toroidal antenna

    Hamed - I'm sorry I'm late to the party, but I see you have been well taken care of. I put up three T90 dishes many years ago and still use them all the time. While I also have motorized dishes, the toroids cannot be beat for instant and multiple access. I only used normal width LNBFs on my...

    Pll Lnb’s

    The argument for PLL LNBs is their frequency stability, or in the loftiest examples, an ability to lock to an external reference. In reality this normally has little meaning for FTA. The argument against PLL LNBs is they typically have poorer phase noise specs within a given price range. This...

    Weak Transponders Only Seen In The Night

    You may be seeing the effect of interference from a transponder on an adjacent bird (like 123 or 127W) with overlapping bandwidth in the same polarization that is only turned on during the day. Smaller dishes, even 1.2 m on Ku, are more vulnerable because of their wider beamwidth, and 8PSK...

    Problem with Prime Focus 2.4M (8 Foot) and Ku Band

    I had a 1.8 m petal prime-focus for a few years. It was dreadfully flimsy, but it was a decent performer on Ku with the same dual ortho feed I now use on the 2.6 m Birdview (sorry I had those dimensions previously as 2.4 m). Even taking the 2 dB loss caused by the dual ortho, on average the 1.8...

    Problem with Prime Focus 2.4M (8 Foot) and Ku Band

    I did use an ADF-120 feed, but it was slightly modified to provide a wider range of adjustment of its f/D. I've tried a few quatro LNBs on this, but I've been happiest with an Invacom QTF-031 (universal Ku). I've made several mods to my dual ortho over the years; I documented most of these in...

    Problem with Prime Focus 2.4M (8 Foot) and Ku Band

    I have a 2.4 m solid Birdview prime-focus with a modified dual ortho feed. Once I had the pole up, the mounting and alignment only took a few hours, and I haven't touched anything since. While there are compromises in the feed, on Ku this beats my 1.8 m offset, and wipes the floor with any of my...

    What switch would go with this Dish T90.

    I have been using three T-90s for the past five years or so. They receive all of the North American Ku birds, and all DVB-S2 signals just fine, and replaced a couple of 1.2 m offset dishes on motors. I'd much rather set up a toroid than a motorized Ku dish - it takes me much less time and is far...

    What is the best DVB-S2 PCI/PCIe card for use with LINUX?

    The Prof 7301 (PCI) and Prof 8000 (PCIe) work out-of-the-box with standard distribution Linux drivers up to data rates of 67.5 Mbps. Above that you need a driver patch, which is readily available online or in various repositories such as V4L-updatelee. All Linux DVB distribution and repository...

    torodiol -t90

    RimaNTSS - that's a very professional looking setup, and a very astute use of the space you have to work with. Hope your installation is soon complete and you can enjoy the benefits!

    torodiol -t90

    RimaNTSS - Your sensitivity measurements are stunningly close to mine. Science and engineering are great. I don't recall if I've posted anything before, but I've attached a photo of my toroid garden, along with another with detail of the LNBs on one of the toroids. This was a few years ago, but...

    torodiol -t90

    I've been using three T-90s for several years now as part of my 15ish dish farm. Everyone seems to have extreme reactions to them. In my case I took down two motorized 1.2 m GeoSATpro offsets after installing the T90s because they offered nothing of value. Admittedly I still have a motorized 1.8...

    PBS Channels Signal terrible in AMC21

    Not to beat a dead horse, but I was curious if my conjecture that PBS tends to tweak their uplink just before the top of the hour in between feeds was true. Today, starting at 0100 EST, I ran a program on the 12180V 30000 transponder that logs any periods of non-zero Bit Error Rates (BER)...

    PBS Channels Signal terrible in AMC21

    Signal quality is not a particularly meaningful statistic unless one only compares values from the SAME receiver model, and then for only the SAME modulation parameters. Thus drawing any conclusions regarding a move from DVB to DVB-S2 based only on SQ numbers will be fraught with peril. What you...

    dvbworld pcie 2006

    I'm not aware of a fully integrated app on Linux like DVB Dream. Normally people use either (1) command line tools to perform the tuning and flow the transport streams to something like VLC or Mplayer, or (2) use a media suite like MythTV or another that I can't recall off the top of my head. I...

    Another Bird View Comes Back To Life!!!

    I'm not quibbling about whether there is a potential difference between the antenna and ground plane. And with the relatively low frequency of an AM transmitter, it will definitely affect measurement devices with high impedances and measurement leads. Depending on the particulars one can light...

    Another Bird View Comes Back To Life!!!

    I'm just not getting it. If the measurements were properly made in a Faraday cage, the only incoming source of RF leakage would be the control cables that crossed the boundary. Given the control pulses probably were below the kHz region and the RF was around a MHz, it should be quite...

    Another Bird View Comes Back To Life!!!

    You can't measure that way. Your meter leads are acting as an antenna and/or the high input impedance of the meter is highly vulnerable to RF. I can sympathize to some extent with you, as 30 years ago I had to design a number of custom digital control and analog audio circuits that had to...

    Ku Frequency Issue With Prodelin 1.8m Dish

    The feedhorn is not going to cause a frequency shift. Could the polarizations be swapped? Perhaps if you could post a few examples from a particular bird on both H & V, that might help us. Is there any chance the feedhorn was intended for circular polarization?

    You will lose a lot of gain with 17 degrees offset from center on a prime focus dish. Unless you dish is very accurate and your LNBs are matched to the f/D of the dish, you will also lose a lot of sensitivity on Ku-band. This may be ok for DVB-S signals, but DVB-S2 signals are much more...

    dvbworld pcie 2006

    While the 2006 does not have the most sensitive DVB-S2 tuner, it is probably not the reason you're having trouble. The same goes for the driver, as long as you're running the latest version. In most cases like this, the limitation is in the dish, LNB or adjustment. Again I don't have a 2006...

    It sounds as though your drivers are working fine with DiSEqC because it works for some of the apps. The main problem seems to be with your DVB World setup. It's likely you will get better help for that on the DVB Dream forums than here. When using DVB Dream, do you select the PC card through...

    Which version of DVB Dream are you using? Did you download the latest drivers for your card? I believe you need to use the BDA drivers with DVB Dream to get DiSEqC to work at all on this card. Unfortunately I only have older DVB World units, so there may be a limit to how much I can help you...
