RTV and Tuff TV

[Thun]

Hi,

My RTV and Tuff TV on AMC 9 on Ku is out. Can someone confirm they are still broadcasting?

:okay:

Scratch that it just came back on... Did that solar stream that's heading to earth knock it out?

[Terryl]

Anything’s possible when a CME is directed toward us from the Sun.

Look here
http://www.swpc.noaa.gov/rt_plots/pro_3d.html if the green line goes above the dotted line it's time for the lead lined underwear.

The red line could affect the satellites signal to us.

Pulling my hair out trying to get these 2 channels when I realised that tp info has changed. Tuff Tv and Rtv now scan in:

11732 V 4439

[secheltpaul]

getting it out here with tp 11735 H s/r 4440 fec 3/4
last night they were on and off a few times with a technical difficulties back soon message.

[Costactc]

That's odd. No signal on the horizontal, quite strong on the vertical.

[secheltpaul]

I just tried the your tp and nothing out here Costa.
I see you are a football fan.

[Costactc]

True and faithful to the Broncos since 1978 Paul, the brunette just adds a bit of spice.

[secheltpaul]

that's for sure.

[Costactc]

Scanned Amc 9 last night with my coolsat 6000 ande it scanned in normally at 11735 H 4440. Really odd that it would scan in on my pansat with different tp numbers even though the sr was about the same.

[Terryl]

Could be that a Xtal oscillator in the Pansat has drifted out of spec, any other TP's on a different bird doing the same thing?

And it’s funny that the S/R is different then what it's supposed to be, that should never change.

[Costactc]

I'm not aware of any other tp on any other sat Terry, The symbol rate was only off by one digit so it wouldn't make a difference.

[Terryl]

I'm not aware of any other tp on any other sat Terry, The symbol rate was only off by one digit so it wouldn't make a difference.

The Symbol Rate is the information packets encoded in the data stream, if they don’t match what is being sent some or all the information will be lost.

This combined with the FEC (Forward Error Correction) with give you your “Q” indication on your receiver, the harder the FEC has to work to correct your lost information (S/R) the lower the “Q” reading is.

This is also known as BER (Bit Error Rate) and is expressed as 10 to the minus 7th power* (bad data, total loss of signal) “Q” = 20% or less, or 10 to the minus 14th power (great signal, no loss of data) “Q” = 99%.

(*sorry couldn't express negative exponents on the page)

Example:

S/R of 4440 = 4,440 Msym/s (Mega symbols per second) FEC = 3/4 (3 original data bits and 1 extra set for error correction) results in 4 transmitted bits of data per symbol, the extra bits are the FEC correction bits, the higher the FEC and S/R the more channel bandwidth you need to transmit your information.


So in short the mismatched symbol rate could mean something was working over time to get you a picture on that TP with that receiver, what was your "Q" like?

[Costactc]

You packing a wealth of knowledge Terry. I still get signal quality on most tp even if the symbol rate is off a few digits.

[Terryl]

Sometimes my brain goes into over drive when I have too much coffee......How is the "Q" on that channel with that receiver?

It could be the receivers AFC* is working overtime to get a good signal.

(*AFC = Automatic Frequency Control)

[Costactc]

Go figure, just did a blind scan on the pansat3500 and it scanned in normal:

11735 H 4439

[Terryl]

??????????????? Had to warm up a bit ???????????

[FARJOHN]

Just checked my Fortec Clasic on TUFF and RTV Good at -------

FRIQ 11735 Vpid 38
SIM RATE 4444 A PID 39
POL H P PID 38

[all-world1]

Just a question....what size dish are you guys using to get AMC9?

[secheltpaul]

i am using a 30'' dish for RTV/TUFF

[easily confused]

I'm using a 39" with an sg2100 motor

[FARJOHN]

I'm using a 39" with an sg2100 motor and ivercom lnb getting 22 sats great

[all-world1]

i am using a 30'' dish for RTV/TUFF

That's great...I didn't know you could get amc9 with anything under 36"

[mydish]

That's great...I didn't know you could get amc9 with anything under 36"

Up to a few months ago, you probably couldn't have. They recently boosted their signal, as it tended to fade out at night.

[Terryl]

AMC-9 has a weird foot print, if you live in one area of Florida you can use a 16" dish, some parts of Georgia you need an 18" dish , 80% of the US and along the US-Canadian border you can get it on a 24" dish, Saskatoon Canada you would need a 28” to 30”.

Here is an active foot print map, you can zoom in on your area and click on it, a marker will come up with an estimated dish size for that area.

They turned up the juice on this one a wile ago. Before it was really hard to get here.
30’’ works great. Good strong signal. Live near Vancouver and still works in all the winter rain we get.
Using a standard LNB

i had a 36'' on it before they turn up power and it was hard to get.
now the 30'' has no problem.

From what I see on KU Puerto Rico is not on the footprint, on C Band I am covered.................thanks.

What size dish do you have for "C" band? If it's big enough you could try it on AMC-9 as there could be some spill over on that Ku beam.

If you have a Ku LNB on that dish.

5.5' feet dish is the biggest dish I have.

[Terryl]

Yah that wont do it, at least a 10 to 12 footer to try for the back scatter, know anyone that has one to try?
