I'm having kind of a weird issue and I'm not sure if the problem is with the LNB's or what. I have more than one C-band dish, each fixed on a specific satellite, and each has a dual LNB. The LNB's are of two different brands. One is an older model, which just so happens to be on my smallest dish, and it performs flawlessly in all weather and has done so for several years. The other type is a newer model. I should note that these are all modern style LNB's that use voltage switching for polarity; none are of the older type with mechanical polarity switching.

The thing I have noticed with the newer ones is that sometimes when it is really cold out (below around 20 degrees F) channels will come in really flaky, in that they have a lot of interference, purple lines or mini breakups in the signal, occasional small gaps in the audio, that sort of thing. You can watch the program but it is not a pleasant experience.

Last night I stumbled across something weird though. As it happened I tuned in a channel on the other side of the LNB, in other words, same satellite but different transponder while it was in the process of recording a program off the same satellite. And when I watched the playback of the recording, I noticed that all the interference cleared up right around the time I had tuned in that second channel and didn't reappear for the rest of the night. Now that could have been sheer coincidence, but it also made me wonder - I would imagine that when one side of the LNB is in use it generates a small amount of heat, but when both sides are in use a lot more heat is generated. Could the circuitry in the LNB have a thermal issue, where it's not happy until it reaches a certain temperature, and causes interference if the temperature is too low?

I only viewed that other transponder for about five minutes but unless it was just coincidence, the mere act of using the other side of that LNB seems to have cleared the interference on the first tuner, and I have not seen this issue occur when it's not several degrees below freezing. I wish I could get some more of those older dual LNBs (the ones sold about five years ago give or take a couple, I don't remember who made them but it was NOT DMS International), they seem to work reliably no matter what but nobody seems to have them anymore. Now I'm trying to determine whether I have a defective LNB, or if this is something common to the newer ones - has anyone else seen this particular problem?

All LNBs experience thermal drift of the LO (Local Oscillator) frequency. Good quality DRO and PLL units drift less and this is one of the specifications that a factory presorts when qualifying the LNB hardware. As a DRO type LNB ages, the component values change and tuning slugs mechanically shifts. Often I run across quality LNBs with very little drift even after 20+ years.

As the TP frequencies are manually inputted in the software list, the frequency might be offset from the LNB IF to start with.

Sounds like your set-up makes it difficult to troubleshoot or even find new channels. That config would drive me crazy! Maybe time to buy a cheap DVBS2 receiver for troubleshooting?
or
Install dual boot OS or get a Goodwill cheap desktop running Windows so you can easily run software such as EBSpro or other user friendly software.

Well I do wish I had the capability, but I don't have any systems running Windows, therefore no copy of Windows to install even if I knew how to set up dual booting, which I don't. Getting a separate computer wouldn't help because I'm not going to start swapping cards between machines. EBSpro looks like interesting software, too bad they don't have a Linux version, although the fact that it's a GUI-based program means it would not work on a server with no desktop anyway.

I did a little searching and came across this article: How to do DVB-S2/S blindscan on Linux, which says "There is already blindscan capability in TBS Linux driver,but to make full use it, you need to write a 'shell-script' which consists of several simpler steps." It ends by saying, "Since not so experienced linux users will have difficulty in writing this "shell-script" by themselves, TBS will prepare such 'shell-script' and include it in the next driver release for easy use of every Linux user." But if they ever did this, I don't see it in their drivers package. I do see two programs:

- szap-s2.tar.bz2 (szap tool compatible with new DVB-S2 aware S2 API for Linux)
- scan-s2.tar.bz2 (scan tool compatible with new DVB-S2 aware S2 API for Linux)

But as best I can tell from the README (which is really confusing to me) it appears that scan-s2 will only scan frequencies from a predetermined list for whatever satellite you are attempting to scan, also it appears it has to be built and then you have to figure out exactly what options to use. Not even remotely as easy to use as the Windows program. There are also Linux programs not specific to the TBS cards, called scan and dvbscan, but they appear to have the same limitations other than that they do not need to be built, at least under Ubuntu, I think you just have to install the dvb-apps package. The thing I don't understand about all those programs is if they will only scan the frequencies in a predetermined list, which is how it appears from the limited documentation provided, what good are they? You're trying to find new channels or determine the correct frequencies, not just scan frequencies you already know about.

Anyway thanks for the response, I don't know if frequency drift is the problem but I guess it is something to consider.

Could you just manually enter the transponder and frequencies at + or - say 10 or something and see if the signal improves at all? since you don't have blind scan and you enter them manually, I would think manually entering is your best troubleshooting method at first. Maybe enter them incorrectly on purpose in both directions and see if it changes the signal.

I thought of that. There are two problems with that approach. First, it's a very intermittent problem that only occurs sometimes, so the trick would be to catch it while it's happening and not when you go to watch a recording two hours later or the next day (by which point the problem has often disappeared for the moment, possibly because the LNB finally warmed up?). The other problem is that the backend software makes this a difficult task, since you can't just change the mux frequency and have it automatically applied to all channels on that mux. Instead, after editing the mux frequency you'd need to delete the channel, delete the service, and then rescan the mux, remap the service, and find the new channel. Also, when you say up or down by 10, isn't that a pretty huge jump? If a transponder is at say 3800, just to pull a frequency out of thin air, I would think that going to 3810 or 3790 would be too much; I don't know what how close to the frequency the tuner needs to be to lock but on a typical LNB but wouldn't you want to first try increments of 1 or 2, for example 3802 or 3798?

The other thing I have wondered is I sometimes see people touting these expensive satellite meters with digital displays that would possibly provide this type of information, and those are fine if you are a satellite professional that uses such an item several times in a week. But I have wondered if it would be possible to make a poor man's version using something like a raspberry pi and a USB DVB-S2 tuner, or even by connecting a UBS tuner to an Android-based tablet or phone and running an app, assuming the tablet or phone has an active USB connection and you can find an adapter to connect to the mini USB connector on those things. I am just thinking out loud here, I have no plans to try and build such a device, not that I would have the slightest idea how in the first place. But, last week I was talking to a guy I know from way back in High School who is now a ham radio operator and he was telling me how the ham community is embracing Raspberry Pi's and in some cases tablet computers to perform functions that in the past would have required some piece of expensive and/or complicated hardware device, and usually at a very significant cost reduction. So I am just throwing that thought out there, not expecting anyone to rush off and build something, but just planting the idea and if it's already been done, I apologize but I am unaware of any such thing.

Several of us on SatelliteGuys have Pi2 / USB DVBS2 systems running various software for the past year. Quite a long SatGuys thread on the projects.

UpdateLee has provided great support for UpdateDVB on the Pi2. There is an active thread on Ricks site .

Haven't gotten around to loading Win10 on the Pi2, but I was thinking that it might open the DVBS software options and ease of operation for more hobbyists.

Did anyone have a price increase today on their equipment? I own my VIP211k's, and they have been $5.00. My bill that I received last week shows the "add-ons" as being $5.00. However, I just logged into my Dish account, and my "add-ons" are now $10.00. Did the additional receivers go up by $5.00 recently?

As I mentioned, my last bill shows $5.00 and under the notes, nothing is mentioned about a price increase.

Apparently it's not an "owned receiver" fee but rather an extension fee that's applied to 2nd and subsequent viewing. Maybe that played into their decision to force a box at every TV- garnering those fees

Possibly. In theory, $9 of the base pack has a rental fee built in. But now is this $5 a chance to get a little more? I don't know for sure. According to chat, it is a glitch and will be resolved in a timely manner, but we shall see. Part of my thinks there is a going to be a new charge, whether it is now or this fall. Here in Illinois, the law requires we are given 30 days notice of any fee changes, but I have not been given anything.

These fees are why streaming has caught on so well across the country and DISH is losing subs each quarter. Soon won't be enough subs to be profitable.

Mexico takes on South Africa to open the World Cup Final (it is called the Final... this just isn't the World Cup Final... Final). The tournament has been plagued with rife malfeasance as FIFA has been committing all sorts of fraud with the ticket sales. Hotel rooms have gone unfilled as the prices to attend a game and stay somewhere are through the roof. I swear this is impacting Mansfield, OH hotel rates which are higher than average for the Indycar race. And there is a broadening VAR presence which will ruin things as nothing worse now when scoring a goal and knowing you can't quite celebrate yet as they check to see if a player was offside by a pixel a half-hour ago.

The Group Stage used to mean something, but now 32 of the 48... yeah, 48 teams are going to the Knockout Round. Getting into the Knockout Round used to be a big deal, even for the US. But now... if you don't lose all of your group stage games, you get to move on. Oi! And this is avoiding all the political stuff!

I have never been so unexcited for a World Cup before. Every game used to matter. But FIFA be darned if they don't try to squeeze out every dime they can out of the players, refs, and fans.

Caught up to the 500... err... k in St. Louis. What a race! Andretti Motorsport were doing very well with Ericsson and Kirkwood, meanwhile Power was moving up the grid. Veekay started cautiously. He was working the tires just right, becoming more lethal later in the stint. Rasmussen was racing likewise, not nearly as insane as he has in the past. Palou was leading the race, in a shocker to all. Caio Collet was having a wonderful ride, making Ferucci potentially sweat a bit. Rain came, rain went, rain came, rain went. Generally mild sprinkles, but enough to pause racing on an oval.

Palou would kind of send Siegel into the wall. Siegel really didn't do much wrong. As he noted, you have to turn at some point. Palou had acres of room below and Siegel might have had his ticket out of Indycar stamped. Dixon was doing the fuel thing and got busted twice by yellows, not pitting before the flag came out. Then the most critical happened... Palou ran out of gas on pit lane, effectively giving Newgarden the race lead and win. Newgarden had a very early pit, so he was able to slide in, get service and go. Meanwhile, everyone else was confused and stuck behind Palou for a bit. Once people figured what was happening, Newgarden had a major advantage of several seconds. Newgarden wouldn't look back and when it went green again, he'd hold the lead for the win.

Massive credit to Juncos Hollinger who bested Penske in getting Veekay out before Malukas in a transition that was oddly bizarre. I haven't had time to check, but I'm wondering if Veekay was about to run out of fuel or cut a tire. He was charging late in a stint, got up to fifth, and then tailed back for a few laps to 10th or 11th. It looked like it was over. Went into the pits, and after the pitting sequence was over, Veekay was well inside the top ten again. It was weird. And he charged, getting up to fourth. He made a late move on Rasmussen, but Rasmussen held his position with some great driving. In fact, there was a ton of incredible racing passing, not passing all race long. Veekay would finish 4th. A podium would have been awesome, but it is a great outcome for a guy who hopefully will get a break with a big team. We saw what Veekay could do with a Honda last season with fuel save, imagine replacing Simpson on Ganassi and having speed to go with fuel saving. His 6th at Indy and 4th at St. Louis get him up to 13th in the points standings and only 5 points outside of the top 10.

Ericsson finished second, resigned to finishing behind the current best in the world guy on a short oval. Rasmussen got the final step on the podium, a nice rebound to what has been an otherwise bad year for him, and a good reward to ECR who just extended his contract.

They raced USAC cars at Daytona once. Once! People died. Aj Foyt said 'f this', and left after the first go around. AJ freaking Foyt thought it was crazy! And cars weren't nearly as fast as they are now.

I think they tried Talladega once too.

So...DirecTV advertises the Choice package with 95+ bonus channels for Satellite customers. You don't want 90+ of the 95...

Excluding PPV, premium networks, infomercial, shopping, religion, and non-English programming, there are 7 channels on satellite that are not on streaming:
NFL Network, MavTV, FE TV, Free Speech, NASA, INSP, and Pursuit. I'm pretty sure a couple of those are public interest that they have to carry to meet an FCC quota on satellite.

I hope they get called out for this advertising because that is ridiculous. One big network, NFL, will probably get added to streaming when their next agreement comes up, and the rest are likely very low viewership.

What about streaming, what do you get extra with the Choice package that isn't on Satellite:
Two stations - one of which is an internet TV - Fox Weather, and Heros & Icons (a diginet). Nothing special here to look at either.

If they cleaned up a couple of their agreements, added a few public interest stations to streaming, they could probably have their lineups match. It's close now, if you take out all the garbage on satellite that they earn money on. If they can sell infomercials on satellite, why can't they on streaming, seems like a miss. A bigger miss, including those stations in the "bonus channels just for satellite customers." Pretty sad marketing right there.

Attached is a comparison sheet of satellite vs streaming for the three main packages if anyone is interested.

MOD EDIT: See Post #3 for an up to date list of what channels are available on sat but not on streaming/internet, see Post #21 for an up to date list of what's available in the app for streaming customers, but not for sat customers.

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....
