i got a lock with the Vantage HD-8000S, but only some broken audio signal

a little bit stronger at 11.30 a.m. UTC

hoi,

vantage hd 8000s with 120 cm in nijega north of the netherlands

11023 h before S88/Q85 now S88/Q95
10964 h before S88/Q97 now S88/Q97
10994 h before S88/Q97 now S88/Q95
11126 v before S89/Q97 now S89/Q96
11053 h before S89/Q97 now S89/Q96

its raining here

Prior to switch over I was getting a C/N of 10.9-11.1 dB on my SatCatcher meter now signal 7.9-8.1 db (85cm Grasse France)

Despite similar set-up to "TonyWhalley" up the road, I'm only getting the Ch5 transponder in Munich City - and then during daylight hours.

Facts...
Ch5:

• At C/N of 1.9dB, picture freezes and lock is lost.
• C/N otherwise has varied from 2.5dB up to 4.0dB during the day and made for good watching (assuming one wants to watch Ch5).
• Prior to migration, I was getting 10-10.7dB C/N on this transponder.

11.023

• This transponder does not lock, but the reported signal level is apparently above the noise floor (whatever that means for a reported "level" of 55% compared with 11.100 received level of ~40%)
• For a few hours one Sunday morning, it did lock with 2.5-3.0dB C/N

Other 2F Transponders

• Appear with "moderate" signal levels (above the apparent noise floor by 10-15%-pts), but are not locking

Thoughts...
Probably some fine tuning would get me a dB or so, and extend reception time.
When the dust settles, I'll probably invest in a 1.5m which ought to buy me a few extra dB of dynamic range (compared to the battered 1.0m in use now) in the link budget.

Dortmund, Germany, 85cm. After switchover to 2F the C/N has dropped from 13 to around 12 dB.

 

[welshman234]

SNR(signal quality) down about 10-12% on 8091 8911 at 73% (normal in evenings here) and all the others ie CH5... at 80-82% SNR as we speak. The Sky HD box curiously shows the Channel 5 bouquet and CH4 HD at 100% signal quality and strength ...........shows perhaps how crap they are as a monitoring tool

Ross a slightly pedantic point but the 80cm in Frankfurt is a Kathrein not Katherin....... A big thanks on the map very helpful.

The 110 cm in Chania South of Greece seems to prove that the oval footprint center at the Southern end runs from London to the Sea of Crete outside this zone the signals drop off dramatically.

Sorted - Im tired and Im making a few typos....

Thinking of another Kath - nice lass ;)

Well nothing is going to happen for some time now so best get an early night for that strange concept called work tomorrow

 

[Lazarus]

Ah, yes: I remember that - "Work" is a four letter word ending in "k".

hoi,

in nijega in the north of friesland in the netherlands it has start snowing now
dish 120 cm and vantage hd 8000s


transponder / dry weather / in the snow
11023 h / S88/Q95 / S88/Q94
10964 h / S88/Q97 / S88/Q96
10994 h / S88/Q96 / S88/Q95
11126 v / S89/Q97 / S89/Q96
11053 h / S89/Q96 /S89/Q95

Although I normally use a Triax TD 88 here on a multi sat set up for reception from 28.2°E, I thought it might be worthwhile trying a smaller dish.

I used a solid oval dish (60 x 50cm) with an LNB from a DIY shop. I've taken the readings using my Satplus meter which is DVB S only and it was partly cloudy but dry.

10964H 66 strength/76SNR
10994H 68 strength/72SNR
11052H 67 strength/74SNR
11126V 60 strength/79SNR

I'm located near the village of Heusse, Lower Normandy, France. That dish is probably more representative of the type a lot of ex pats use for their reception here.

The 110 cm in Chania South of Greece seems to prove that the oval footprint center at the Southern end runs from London to the Sea of Crete outside this zone the signals drop off dramatically.

The pink flag with no central black dot is no reception in Chania.

The furthest south east reception atm is the yellow pin for the 150cm in Bologna in northern Italy,a nd that ones right on the edge soi its debatable if that pin should be pink with no dot as well as theres no hope of the reception holding up when it rains...

 

[william-1]

Thanks for that info Analoguesat

Here is the possible sequence of events to follow @ 28.2 east

Astra 2F is reported to not be able to cover 10700 to 10950 so we will probably have to wait for the launch of Astra 2E that covers 10.7 to 12.75GHz as does 2G,

I still find it hard to believe that Astra 2F cannot cover these frequencies unless this was a part built Eurostar E3000 satellite meant for another location ? so may have been used to get the African service up & running quickly that it has done & by 27th November as scheduled,

Next sequence of changes at 28 east transfer of transponders from Astra 1N to Astra 2F:
11.023 H, SR 23.000 FEC 2/3 DVB-S2 *PSK "8901" and "8911" (BBC 1 HD's) already there
10.964 H SR 22.000 FEC 5/6 (CH5/5USA/5*/Channel 5+1),
10.994 H SR 22.000 FEC 5/6 (ITV 1 Granada HD/ITV 1 Central South West SD/ITV 1 Anglia West SD/ITV 1 Meridian North SD/ITV 1 Yorkshire East SD/ITV 1+1 Yorkshire SD),
11.052 H SR 22.000 FEC 5/6 (ITV 1 Central South SD/ITV 1 Central East SD/ITV 1+1 Wales SD/ITV 1+1 Westcountry SD/ITV 1+1 Tyne Tees SD),
11.126 V SR 22.000 FEC 5/6 (Channel 4 HD/4Seven SD)
Completed.

The next part of the change over is dependent on the capability of Astra 2F to cover the Ku band below 10950 for the transfer of all transponders on Astra 1N if this is not possible then we will have to wait for Astra 2E launch in the 1st Qtr of 2013.

Phase 2 4th Qtr 2012 will be the transfer of Astra 2B transponders to Astra 2F
11739 V
11876 H
11895 V
11954 H no transmissions atm
11973 V
11992 H
12012 V
12032 H
12110 H
12246 V
12304 H
12344 H
12402 V no transmissions atm
12441 V no transmissions atm
12480 V

Astra 2B will then move to 19.2 east

Phase 3 1st Qtr 2013
Astra 2E will then after a successful launch will replace Astra 1N @28.2 east
Astra 1N will then move to 19.2 east

Phase 4 1st Qtr of 2014
Astra 2G will replace Astra 2A & if allowed to the 3 satellites 2E,2F & 2G will cover the whole of the Ku band 10.7GHz to 12.75GHz @ 28.2 east.

Have a look at slide #25 & 26 here @ www.ses.com/11572422/120522_CDO_Investor_Day_FINAL

from 22nd May 2012.

The interesting thing is slide #26 is stamped 'corrected slide' - so what date was it corrected....? But taken at face value it infers that 2F was always scheduled to be a replacement for 2B African beam.

Tin foil hats to standby.
