Question about 101 signal strengths

    I just checked my signal strength for the heck of it. I haven't had any problems, but just like to check it periodically. Anyway, my 101 numbers are a little lower than they have been. We do have light rain here today in northern california, but I did notice that almost all my odd tp's are in the 80's, and even are in the 90's. The numbers aren't terrible, but lower, and just wondering what significance, if any the odd/even tp thing has. Here are my numbers:
    101
    85 92 81 97 82 97 85 97
    83 95 83 97 84 99 84 99
    86 0 84 100 83 99 87 98
    91 0 93 0 91 98 86 99

    This is what they were in july, when I moved and aimed the dish:

    101
    95 96 92 100 92 99 95 98
    95 96 94 100 95 99 92 100
    95 0 89 100 90 99 93 98
    95 0 95 0 95 99 91 100


    Thanks in advance!

    those numbers seem to indicate a developing issue with either a loose connection or a bit of corrosion. remember that half the transponders work at 13V and half at 18V. the 18 V will work with a voltage drop (say to 16V) but the same drop on the 13V puts it a bit too weak. Just check your connections to be sure they are clean, straight and dry inside

    O.k. when it stops raining, I'll do that. I'd find it almost impossible to believe any moisture got into those connectors, but you never know. If they're dry and clean, then what? Any other possibilties? I just want to know all the options so I can fine tune this when the weather breaks.

    It's possible you have a bad LNB developing as well.

    O.k. thanks. I've been meaning to order a spare just to have around anyway.

    Is it raining right now when you are taking those signal readings? Or any bit of cloud cover, even in the distance?

    All could lead to slight drops in signal strength.

    I wouldn't expect drops on just odd transponders from 101 due to cloud cover or rain.

    That was my thought as well.......I've checked it many times during rain, and have seen consistent drops on all tp's, but not just odd or even.

    do you have just one rcvr or more than one.
    more than one and readings on all units like you posted could be (Low Probability) a bad Switch. I suspect however that it is just one lose connection

    Some of the evens are down a bit as well, so I thought I would ask ;)

    3 - 4 points vs 10 points?

    I have 2 receivers.....the HR21, and an old hughes in the bedroom. Guess I should check the 101 on that receiver as well, and see if it is relatively the same numbers as the HR21. That would indicate possibly a bad lnb, correct?

    I would indeed check 101 on the hughes

    O.k. checked the 101 on the Hughes, and the 101 on the HR21 again:

    101 (Hughes)
    91 90 84 97 88 96 91 93
    88 92 87 97 89 97 83 96
    90 0 86 100 85 96 86 96
    90 0 92 0 86 96 86 96


    101 (HR21)
    88 92 83 97 85 97 86 97
    88 95 85 97 88 99 85 99
    90 0 85 100 86 98 88 97
    93 0 94 0 94 98 86 99

    Though they seem fairly consistent with each other,there still seems to be a pattern with the odd tp's..... to me anyway, but please, anyone that sees different, or confirms what I see, I'm all ears. Like I said, not having picture problems right now, but since I noticed this pattern, I'd like to figure out what it means and resolve the problem before it's worse.

    do you have a multiswitch or a swm in your system if so the issue is between the switch and the dish. no switch or swm it is the LNB

    Nope, I'm straight from the lnb, using 3 of the 4 outputs.......very straightforward. You think it's more likely the lnb now?

    LNB about 98% likely. get a spare.

    I see that 3 lnb ka KU dishes are now standard install.

    Yep. I checked Ebay earlier........waiting for reponses about the brands, as I want a WNC like I now have. I'm almost just as well off buying another complete slimline, as it's amost as much by the time you pay for the lnb and shipping. My dish has a few scratches and is starting to rust anyway......

    Really? I have seen SL5 LNBs for around $20-$30 and the complete dish setups are usually around $80-$100.

    There are a few slimlines on Ebay right now for under $60.00 with shipping included, but that's still half the cost of a lnb. I'll probably but just the lnb, because I don't want to spend more than necessary, unless I see a deal on a compete dish that I just can't pass up.
