Hi Folks,

This is Eugene in Seatac, WA.

Hey, I have a question to ask.
Just curious.....

FIRST OF, I enjoying watching ABC feeds on C-band,
which is on Galaxy 16, C-band.
FINALLY got ABC feed signal in months!!!! : - ))))

The question I have in mind is, just about every day
at around noon Pacific time, ABC feeds is seem to be
breaking away or kind of lost signal.
So, since this been happening everyday at around noon
pacific time. Then at around 1 PM Pacific time or so,
ABC got cleared.

So, I've been thining and wondering, could this be
a "SUN SPOT" like we've seen when we used to see
analog signal and the sun spot shines on the solar power
on the satellite. ?????

I figured it might be sun spot, because right when it happen,
I also notice that the sun is at around 90 degrees west, same
as my BUD pointing at Galaxy 16, at 97 degree west.

I know it's NOT the wind, which usually does shake my BUD
to lose signal. But this time, as I'm typing, TODAY, NO wind
at this noon hour.

So, do we still get sun spot effect even though we're seeing digital FTA????

Thanks,
Eugene

It can't be a Sun spot, and it's not yet the time of year for the sun to be low enough in elevation to get "behind" the satellite at whatever time that would happen at your location when it finally is that time of the year.

11:25 AM PST:
ABC East is showing soap opera and is breaking up, and the sun
is coming right at 97 degree west, because that's where my BUD
is aiming at.
ABC West is showing color bar tone, NO break-up at this present time.

Whenever ABC West or Mountain time zone shows shows soap opera,.
there's a break-up from 12 noon PST to after 1 PM PST.
NO WIND at this time.

But it seems to be doing this daily.
Even the "Little Ledge" on last weekend, Saturday and Sunday.

NO break up after the sun gone by 97 degree west.
NO break-up on the rest of the afternoon and evening.
JUST from 11 AM PST to after 1 PM PST.

However, IF one of ABC feeds, whether if it Mountain
or West, shows color bar tone, it sometimes clears up the break-up.
NOT always.

So, that's my experience seeing ABC feeds on
Galaxy 16, C-band at 97 degree West, daily.

Hmmmm.

It's 11:30 AM PST right now as I'm typing, and
still see breaks up on ABC East, while ABC West
is showing color bar tone with NO break-up.

Nothing to do with sunspots or the semi annual solar outage as it is the wrong time of year for the sun to track behind the Clark Belt as Primestar31 commented.

I am having problem following the description of what satellite you are watching and where the dish is aimed where when ABC channel goes away...

ABC feeds are on 95w and 99w. Don't know of any ABC feeds on 97w.

If you are referring to viewing the ABC feds on 95w or 99w, and the channel disappears when the sun is at 90w or 97w, then I would assume that the feedhorn FD is not set properly and it has strong off axis lobes.

I have some of the ABC feeds breaking up, but they are on 99W.

The ABC feeds are all on the same transponder and use a high FEC ratio, so the problem is likely related to signal quality and error correction. A lower signal quality near the signal threshold may result in adequate FEC to provide reception of static color bars (no movement), but any programming with motion would not have adequate signal quality to decode.

What is the Signal Quality reading comparison readings when no problem vs breaking up?

Did you try adjusting the horizontal polarity skew to optimize?

What size reflector?

Titaium,

Sorry, excuse me for my mistake. Galaxy 16 is on 99 West.
ABC feds on Horizontal, channel 2069 to 2074, Horizontal, C-bamd.
AND as I'm typing NOW, which is 2:06 PM PST, ABC West
is breaking away showing soap opera.

I know this will clear up later in the afternoon.
The question is, WHY this happening everyday???

Thanks.

10 foot mesh dish antenna with Co-Rotor II feedhorn, and
with a NEW servo motor. And Norsat 8225R C-band LNB.

Horizontal skew is always on "0".

Remember, Titanium??? We talked about this before when
I was having problem with my servo motor wiring connections
and etc, last spring. : ))))

And you're right that when you posted about that ABC's break up
and is using a high FEC ratio, maybe that's the problem I was having
from October of 2017 til January with the new servo motor, that I
couldn't get ABC feeds after all that time.
I also mentioned it on the other forum, before.

So, with ABC's high FEC ratio, I agree, but should have resolve.

I bet TV are required to have some kind of filter or something
that prevent break-ups. ???

Did you try adjusting the horizontal polarity skew to optimize? "0" may not be the absolute best angle for this transponder.

Not aware of any sun filter... LOL

Signal Quality is 99 % reading without break-up.
However, when there's a break-up, the signal quality
is still shows 99 % on the GEO SAT PRO HDVR-3500 receiver.

No, I have NOT try using the skew on the analog receiver
which I slaved the GEIO SAT PRO to.

I'm seeing a signal in the mid 90's. It is more of a freeze than a break up that I see and it is only on some of the ABC feeds. Others are fine.

Oh, yeah, that's right, "Freezes" instead of break-up.
But it still will do it again during the day, whether it's sunny
or cloudy, like it is now, today in Seattle. It rain a little, today,

But with the ABC's high FEC ratio that Titanium said,
I want to share what my 26 years old nephew, Jordan told me.

My smart 26 years old nephew said with the old servo motor,
the small DC port in the center of the servo motor in the circle
which contact the feedhorn probe worn out because I've been
on ABC feeds for a long time, and with that FEC ratio, it
killed that little DC port on the servo motor.
That what he told me. He's a genius because he already
knew why when he saw other channels on Galaxy 16 that
aren't high FEC ratio. Their're quality signal shows 6 %,
like MeTV and others.

He's understand about high powers and lows.

This was back in January when he installed the NEW
servo motor.
He thinks the more I tune on ABC feeds with their high FEC ratio,
the more it will kill my servo motor's DC port.

: - ))))

Sorry, but your nephew may be smart in some things... understanding servo technology is not one of them... LOL

Watching high FEC signals has XERO relationship to servo motor failure.

The dish aiming, the feed FD, the FL placement and the skew must be optimized to receive ABC on a 10 foot dish. Any interference or reduction in signal will introduce errors that cannot be overcome by the forward error correction.

Freezes on ABC channels during inclement weather or noise from the sun indicates that your dish or feed is not optimized and likely needs minor adjustments as described in previous posts.

The OLD servo motor I'm referring to was 15 years old, when I found out
in October, 2017, NO SIGNAL on ABC feeds. Compared with the NEW servo
motor in January, 2018.

Yes, servo motors will fail. 15 years is a good long life for a servo!

When your motor failed, it couldn't rotate the probe to change between polarities. Nothing to do with the FEC, everything to do with polarity.

I went to install a dish for an elderly man once and when I got there, he told me he knew right where to put it. I ask how he knew that. He said his grandson was outside last night with a pair of binoculars and could see the satellites. I told him his grandson must have one powerful pair of binoculars because those satellites are 23,300 miles away. It would be like looking at his pickup truck at that distance. :)

Hey, Just want to inform you that TODAY, Saturday August 25th,
For the FIRST TIME in weeks, ABC feeds isn't using their high FEC ratio
that causes freezes. I guess it's because it's Little Ledge World Series Day, ALL Day Saturday.
So, in case you missed this Saturday, I'm reporting you that NO Freezes
on ABC feeds.
It's 1 PM PST, here at my end in Seattle.
Okay???
I'm just monitoring my favorite satellite feed,
doesn't mean I like the little ledge baseball, thing. : - )))
So, NO high FEC ratio, TODAY.
NO Wind, either.
That's my report.

Ed from following on the other forum, first I am glad you are getting your signal today wheather or not they changed the FEC. Truth has been told and I will repeat it again. You need to fine tune your dish AND feed!
