    I had an installer come out (private contractor) last friday and installed a SWM system. The new apartment i moved into already had the slimline 3lnb dish setup on it so all the installer had to do what fish coax thru my addic to a 4 output swm splitter. Using two outputs on it one to my HR20-700 in my living room the other to my HR21-700 in my bedroom.

    The lines he used ...........for the bedroom he fished a new coax down inside the wall to a wall plate he installed. The 2nd for the living room's hr20-700 he used an existing comcast coax that was already fished down the wall. He just disonnected that run from the comcast splitter in the addic and put it onto one of the outputs on the SWM splitter.

    The first nite the install was done the signal strengths on my hr20-700 were in the 80's some in the upper 70's (and they flucuate alot) and the installer couldnt figure it out so he was going to come back the next day to try and fix it. The bedroom hr21-700 all signals come in 95-100 and hold steady.

    That nite it was driving me nuts so i thought i could figure it out myself. I did some research online and read the closer u have your Power Inserter to the dish the better. He put the PI on the run to the living room which is like 1/4 longer than the one he ran into the bedroom so i moved the PI into the bedroom and boom issue fixed. HR20-700 signals jumped up to the mid 90's and held strong for 2 days.

    Then last nite i was checking the signals on my hr20 and found it reverted back to the strengths they were after the installer left friday nite. I thought at first it was the existing comcast cable run he used but then i attached brand new rg6 coax from the splitter into my hr20 and at first the signals came in.....in the upper 90's but as i sat there and watch 5 minutes later the signals degraded and were back in the upper 70's and 80's.

    I'm thinking these possiblities. If anyone has anymore feedback i'd appreciate it. 1: HR20-700 tuners are bad. 2: SWM splitter is bad 3: Power inserter isnt the greatest or might be defective (it's the model PI-21).

    So today i'm going to do a few tests. I'm going to put the hr21-700 that's in the bedroom and receiving great signals onto the run in the living room and see what i get on that receiver. If the signals are good i guess the dvr in the living room's tuners are going bad. If signals are bad on my 2nd receiver then i'm going to move onto the next step.

    I got a new power inserter from solid signal and it's due to arrive today i'm going to put that on and see if that fixes the issue.

    Lastly to see if it's a splitter issue i'm going to take the run in the addic from the satellite and run it directly to my hr20-700 (of course with the power inserter attached).

    I've tried calling the installer several times today but i guess with the holiday on hand people arent working so for now i'm going to try and fix this issue myself.

    I don't see where you're asking a question, but it does seem like the first step might be to swap receiver locations and see if the problem stays with the location, or the receiver.

    My swm16 died the first night it was installed. It was replaced the next day and is working without any issues. The tech said that he only knew of one other swm16 that failed and had to be replaced.

    Well i'm just asking if this could be a bad splitter or bad PI? If not what other possiblities are there b/c the run from the sat dish is fine i hooked it in drectly to a dvr and all 95-100. Just wondering of anymore posssiblities besides a bad splitter, bad dvr tuners, bad power insterter that i'm not thinking of.

    Well i brought the bedroom dvr (hr21-700) that is getting good signals into the living room where the hr20-700 signals are bad. The signals now in the living room are 95-100 connected to the hr21-700. Hmm looks like maybe the tuner on my hr20-700 is going bad (well at least the SWM one---well it's labeled FTM).

    I have an esata external drive attached to my hr20 is there any possibility that could be causing the signal strength issue? Anyone else with an hr20-700 experience issue with it working with SWM?

    EDIT: OK odd i just put the hr20 in the bedroom and hr21 in the living room and now the hr20 is getting great signals from the bedroom location. Ugh looks like i just need to switch receiver locations. That sux too b/c my hr20 has an externam 1tb hard drive on it

    OK, give it some time with the receivers swapped and see if anything changes.

    It's starting to look like it's only a cable connection problem.

    Yah i'm going to give it an hour. B/c last nite i ran new coax's to the hr20 to see if the wiring he did was bad. At first my new coax worked good but after about 10-15 minutes the signal degraded so yes i'm going to let it go and watch.

    The power inserter is in the bedroom now with the hr20 could that have something to do with it? Does the PI location have anything to do with maybe the receiver that is "attached" to it might get better signals?? I know i think that's a stretch but just trying to rule out all possibilities.

    It's pretty sad i paid a contractor to do this work (200 bucks) and here i am the one that is most likely going to find and possibly fix the issue. If switching receiver locations is the fix guess i'm gonna have to get a 1tb external hard drive for my hr21 too

    "Seems unlikely".
    The 21 volt PI doesn't work as well as the 29 volt, due to the lower voltage, but by this I mean that the voltage drop over long coax can be a problem.
    I've used for years a 29 volt PI with 100' of coax without any problems.

    While we can't do the work through the internet, we can try to help you through the problems.

    It's funny after the guy left friday nite he had the 4 output splitter wired up all wrong and i had to redo it (after some internet research). He didnt even have the line coming from the power insterter that goes to the splitter into the right output that connects the power to the lnb (in my case on my splitter output 1). He had the PI line going into output 4.

    UPDATE: After about 30minutes of switching receiver locations now it looks like the hr20's signals in the bedroom are starting to degrade. While the bedroom dvr i moved into the living room are still very high.

    Looks like i'm going to be calling DTV and swapping out my HR20-700 :( It has to be the HR20-700 b/c the Hr21-700 gets 95-100 signal strengths in both locations. Right??

    Hmm maybe i should just get an HR34. I mean crap the only reason i have a bedroom dvr is for the extra 2 tuners i never even watch tv in bed.

    OH sorry i just emptied it.

    Well if i'm going to get a new receiver i might as well go for the HR34. I think i'm going to get one from solid signal instead of getting a refurbished box from directv. Then send back my hr20-700 to dtv
