    In the "old days" (like decades ago), frequency instability due to heat was a serious limitation in the design of RF oscillators. Since the advent of phase-locked loop (PLL) frequency generation technology, this problem has FAPP been solved for most applications. This has made the utilization of SHF satellite and cell phone frequencies economically feasible in CE equipment. So while it's true that LNB's can develop heat-related problems, so can any other piece of electronic equipment, like, er-uh....the H20-600. :)

    The heat of the day cannot affect any B-band converter that is installed properly at the rear of a DIRECTV receiver.

    The heat of the day can affect an LNB that has or is developing a problem. Defective LNBs can and should be replaced.

    Class action lawsuit? :bad_nono:

    Back during my days in Law Enforcement, the DA in our county was lamenting the fact that we were back in court for another lawsuit.

    I asked him why?

    Well, I don't have air conditioning and when we get a nice HOT day (which is not all that often in Seattle, but it does happen), the heat of the day can most certainly affect a b-band converter at the back of my TV (at least as much as it could affect it outdoors). :)

    I agree, the OP is either a very uninformed and dissatisfied customer, or a troll.

    How come only the B-band frequencies are affected by heat? I know, they must be sub standard to A-band, you know, like a B movie. I say class action lawsuit. I live in Central Florida and have an HR21-700. It gets very hot here and the only time I have any problem is in very heavy rain. I've had Directv for 10 years now and heat has never been a problem.

    Hey . . . I don't resemble that remark!

    The heat that a BBC would encounter in a house that’s not air-conditioned is nothing compared to if it was improperly installed outdoors somewhere that was exposed to direct sunlight.

    Jun 29, 2007 order to diplex OTA, I had the BBCs in a sprinkler control box (that now houses the SWM-8) on the side of my house.

    It was 100+ for more than a few days. Who knows how hot it was inside the box?

    The BBCs never failed. But, I had a few ready...thinking they might.

    Is this intended as a news item?
    Could this be because the local TV station is assuming that one person's bad experience must be a result of a design flaw???

    All electronic devices run a risk of heat failure and there's always going to be defective devices out there. DIRECTV has experienced just about everything that can go wrong with electronics equipment on the HR2x and drifting B-band frequencies isn't one of the prevalent problems.

    The other part of this story that is a total crock is the idea that adding more satellites is going to make the problem go away. It was precisely because satellites were added that the new stack plan had to be instituted. Four satellite slots worth of data simply doesn't fit easily on a coaxial cable so they had to annex the frequencies that used to be set aside for broadcast TV.

    Your TV station friends need to get themselves some reality.

    It's the end of days people, it's the end of days!

    Harsh is actually defending (in his own way) DirecTv. :eek:

    Harsh has not been his usual self the last few days, he's actually been making factually correct, on-topic, non-bashing posts.

    must be the heat of the dog days of summer getting to him....

    ...or else we won him over with our aggregate charm and wit.

    The B-band converters use technology that has been around since the 1920's. All it does is move the 250-750 mHz IF to the 950-1450 mHz band. It is not flawed technology. You should learn a little RF electronics before you make comments like that.:nono2:

    B-Band Lawsuits? Lawsuits shmawsuits. Bring 'em on Baby!

    I got the best law firm in the nation to drag this lawsuit out to kingdom come: Dewey, Cheatham, and Howe. We'll be broadcasting from the moon before this is settled!

    By the way, you should sign up for our Protection Plan. Well worth the extra $5.99 per month, especially if your B-Band converter CATCHES FIRE! Ha! Ha! Ha!

    Can't wait to tell my Board about this one. Next someone will be claiming that our sat signal causes health problems. Nut jobs everywhere!

    Have actually had trouble with this in east Mesa during the day (when no one's home and the a/c stays off; indoor temps can easily get over 120 by the time anyone gets home). Rights itself with either some jiggling of the BBCs, disconnecting and reattaching the BBCs or, in a few extreme cases, a quick (ha!) reset.

    Thought at first it was related to new software installs, as the first time it happened was in the middle of a software download; when it started happening more regularly, I figured it had to be heat-related. Fortunately, I don't ever DVR anything during the day, so no biggie.

    @120 ambeint temp I'd be realy worried about the dvr.. especialy the harddrive inside..

    Must be one powerful A/C system to cool the house back down 40 degrees.

    I'd be worried about more than just the BBCs/DVR if you let the inside temp get anywhere above 86ºF!! Even if it is a dry heat! All your electronics could get fried.

    If you have any medications in the house - they'll go bad. Just about anything you buy, food, electronics, etc has warnings about storage temperatures and most say not to exceed 86ºF.

    I think it'll actually cost more $$ to cool the house back down from 120 than just turning up the A/C to say 82ºF when you leave and back down when you get home.

    At those temps the ice cream in your freezer would be melting...
