    Getting a crash course on D*...the good, and the bad :nono2:.

    I was sitting here watching "Law Abiding Citizen", a movie I had been wanting to see, and it was just getting good with 20-30 minutes left. I heard what I thought was thunder, but you learn to ignore that here in south Florida as you hear thunder in some shape or form most of the time (a big clap just hit as I typed that).

    Anyway, there went the sat signal and now I'm staring at the bouncing logo :eek2:.

    I guess I need to learn to use the DVR to its full potential and get my H24's online with the HR24 to watch some recorded stuff until the rain passes.

    Live an learn :D...

    *edit* - rain passed and the movie just came back on...rolling credits!

    If you were watching an HD channel, switch to SD until the clouds and rain lightens.

    Because the SD signals sent by the Ku band aren't affected as much as the Ka band (HD). You might have gotten lucky by switching to the SD channel.

    You might want to post your signal levels here, too, even if it is a brand new install. Low levels are often the cause of rain fade. Folks here will help you with that.

    And welcome aboard. Hopefully you find more good than bad with DirecTV. I sure have. :)

    SE Florida here, Boca Raton to be specific - I have not had a rain fade event yet this summer - check your signal levels....

    I used to live in Springs but I'm in Weston now. I do get up to Glades Rd. on occasion.

    I think I was checking my signals correctly but maybe not. D* was reporting the signal to be in the 90% range, first time I checked it was like 97% and then the other day it was 93%.

    Not sure what it was during the rain but the rain was coming down good!

    Well, for sure the western communities see more rain fade from the big Everglades boomers. I live less than a mile from the ocean. Your 103c and 99c numbers would be of biggest interest...

    Starz will be replaying this movie many times. Just do a guide search, highlight the movie, press the Info button, choose "View Upcoming", pick a date/time when rain chances are low (middle of the night?), record the movie, then watch it at a later time.

    What I did this past week, to ensure Eureka and Haven would record. I knew storms were approaching so I set my DVR to also record the SD version of both shows in-case the HD was knocked out. Fortunately the storms passed before either aired. So the HD version was fine. Too bad the DVR can't "sense" when HD signals are fading and switch to the SD feed automatically.

    Not sure what all that means but it really was a downpour, a short one at that. My old (still have it) cable service is DirecPath which is vanilla D* for MDU's. From time to time, we would get rain fade from it. So, I'm kinda used to it but it can still be a PITA.

    FWIW, it has been raining heavily here for most of the night. I got stuck re-wirng my home run panel ('cause I'm like that) and have been re-booting the H/HR receivers. Suffice to say, the D* signal has been solid despite the rain :righton:!

    With the signals you posted above it should take a pretty heavy cloud to kill your signal. Just remember that it won't be the cloud right above you, it will most likely be a cloud southwest of you in the line of sight to the sats.

    Given the fact that he is (1) a new install and (2) has no readings for 110W and 119W on his report, its very probably he does not have access to the old Ku SD MPEG2 feeds on those birds, in which case, switching to SD does him no good.

    I was noticing LOS about every time it would rain, which is unusual. Sure enough, ka band signals were in the 60s, under clear skies.

    Finally had a tech out to re-aim. Now all is well. All 5 sats have consistent readings in the 90s.

    I had a perfect opportunity last night to test out the concept of "rain fade"...which I personally think is not a valid term.

    About 9pm last night, some very severe and dense lightning/thunder clouds rolled into the area for about an hour. NO RAIN...not a drop. I got a 771 searching.... message for about 4 minutes on all HD receivers. Then the signal returned just fine.

    At 10:00pm, it monsooned....I mean poured big time (found out this morning we got 2 inches of rain in an hour). Not once did I lose my signal, not even for a second. So much for "rain fade".

    The remainder of the evening...as more clouds and rain passed through...no signal loss - only that one 4 minute drop during the initial roll-in of heavy, dense clouds. I recorded programming all night long to test this. My signal levels are all in the 90's..mostly mid to high 90's.

    I have now seen this same scenario play out 3 times....so from my vantage point - it should be called "Dense Cloud Fade" or "Severe Thunderstorm Fade". Rain is not a primary contributor, nor guaranteed to lose the signal.

    I agree with you on your observations of the 771 searching for signals message, hdtvfan0001. It seems that prior a severe thunderstorm is when I lose signal. Although I usually don't regain signal, especially on HD channels, until the heavy rain stops.
