I don't know who does their tech support, but its a relatively small company and they were responsive in the past. I just thought these problems couldn't /not/ be addressed sooner rather than later, you know?
FYI, the most problematic channel was TBS HD... I rescanned and it is indeed a weak channel on QAM 114.205 - and its' weak. The only channel I have higher than that is TNT at 117.205, and that channel is flakey too but I never watch law & order, so... Anyway, I found the 480p version of TBS and added that, and that channel is fine... the HD is a mess though. Not sure what to do after that?
I've been watching TV on other channels and not having a problem in the past day or so - but also I have changed out of the hard drive that was giving intermittent errors.
@2wheels - The inside/outside thing is a good question, but you probably want to strive to have only 1 junction between the entry point to the house and the amplifier... does that make sense? Once the connection comes into the house, it would be optimal to have a continuous run of cable to the amplifier and then continuous runs of cables to the devices? I think the only reason to put the amplifier outside is if the lines branch out from an exterior point of contact, not because you want to amplify the signal earlier rather than later. However, I'm no engineer and I could easily dream up scenarios where amplifying the signal earlier rather than later could help... but not usually.
makryger wrote:Sounds like a plan. Yes, I would install the motorola amplifier before splitting the internet and tv signal. In a perfect world, you should only split your signal at one junction. In other words, one cable comes to your house, then that cable is split all four ways at once- using a four-way splitter like this from monoprice. It's generally not good for the signal to put splitter after splitter. In fact, had I known that your signal is split that many times, I probably would have recommended trying that first. Although, as I explain below, results can vary. I'm reading one review of that monoprice splitter that says it doesn't work well for his cable modem, but does for TV... which doesn't make a whole lot of sense.
Unfortunately, while all of this makes sense theoretically, in the real world, it's very difficult to predict that adding or removing components will make a difference, unless its very obvious that the signal level or SNR is low, which is not the case for you. I'm not sure if you've bought the motorola amplifier yet, or what else you've tried, but you should know that doesn't always fix the problem. So I would recommend to you to test things about before going through an elaborate installation (like what you mention regarding getting power to the amp.) Before the amp even arrives, you could try temporarily removing the three-way splitter, and seeing if that improves your image. If it does, that'll suggest to me that an amplifier will probably be helpful. Also, when you do get the amplifier, it would be wise to test it first before a huge installation. So try to get ahold of a long extension cord to power the device (or a long thing of coax cable), and then just put it in line, and see if it works. It may turn out that it doesn't help, and you may have to return it.
makryger wrote:@2wheels, could you do me a favor before ordering the amplifier? Trying removing the three-way splitter and plugging in the cable that goes to the HTPC directly into the two-way tv/internet splitter. Then check your HTPC to see whether that has any impact on the signal. Afterwards, you can go back to the original configuration.
@rob, I am no signal expert... I just know stuff from my own experience and what I've read. But from what I understand, the internet and tv signal are really the exact same signal- they just are transmitting different information. So I'm not certain about the cable/internet split vs just splitting it all at once. I guess 2wheels will just have to try both and see which resolves things.
robthecomputerguy wrote:The signal may be the same but the special splitter is required, and internet can only be gotten through one of those ports on the special splitter. It's not a 2 way splitter, its' a signal splitter of some sort. That said, it's not necessarily wrong to amplify the signal before splitting it, it's just so unspecific to us laymen.
makryger wrote:If it was just a two way splitter... I don't see how that could make sense. if it was a three-way splitter, then one is -3.5dB, the other two are -7.0dB, so a swap between 3.5 and 7 could cause a difference.
makryger wrote:If you're getting the weak signal, that makes me think even more its a signal issue. As I mentioned before, Media Center for some reason needs a better signal than some other sources to get clearqam working. Maybe try lugging your computer to another coax outlet in your place and seeing if that makes any difference. What you may end up needing is a signal booster (motorola makes the best one).
