Türksat 5B (42E)

Can you see 45 East AzerSpace/Int 38 , beacon 11703.00 RHC, or 46 East beacon 10950.10 LHC to get a reference Simon
Also on 45 East 12747.00 RHC

Will take a look this afternoon and report back.

John, I know there's great potential for getting this wrong or opposite. Firstly, I pointed the dish at 1W without the slab inserted and set the LNB correct for H & V [H=18volts, V=13volts]. Then with the slab inserted I went to Azerspace 1 & 2 beacons and this is what I found: @46E 10950.1 is RHC. @45.1E 11703.00 and 12747.00 are LHC.

Hmmm, set me thinking now - the ones you say are LHC are actually documented as RHC only in 'frequencyplansatellites.altervista.org and that's the same as what i find. I'll look into it further, thanks for doing the checks.

Does the angle of the plate affect which circular polarisation each probe receives? My C-band LNB received the opposite of what I expected but I never tried the plate in the opposite orientation.

 

[SimonE]

Don't worry guys! I have found the original paperwork . See jpg . There's only one slot for the slab and I was set up 90degs out. I will recheck by twisting the LNB versus the slot. So you are right John apologies. SimonE

Rechecked and now in sync here with the rest of the world! 5B beacons are 11452.7LHC and 11704.45 RHC.

Excellent - iv'e cancelled my visit to the doctors for a brain scan lol.

Possibly narrow marker action taking place from 5B - 11224.5 V - high and low levels taking place.
High and low level markers taking place - 11264.65 V.
Another marker at 11450.6 V but not sure about it .

Thanks John! I can see some peaks (without constellation via CS) in ext. Ku band range.

here are the two spectra characteristic of beacons
obtained with a TBS6983
at home the beacon of 11704 is rather on 11699
but it can come from my LNB which is not too precise

11345.00 V very strong - signals popping up randomly at different frequencies - mainly V at the moment.

10743.00 H marker now seen

First carrier in ext. Ku-band: 13442

@dx qwer

Well done with finding the carrier, I think it is probably the first one reported on this forum.
Glee fest for the wavy line men, Chinese extended Ku LNB's getting strapped on as I type...

@dx qwer
I had a sneaky feeling that since i didn't see any more normal Ku test action from Saturday onwards that they might be doing activities elsewhere but every time i checked Upper Ext Ku there was nothing showing. - Great catch .

 

[dx qwer]

@John,
flat spectrum since perhaps a half hour... probably later again?

 

[John]

10743 H marker up now at 6.35pm UK time

 

[John]

Early morning activity on both normal Ku and upper Ext Ku at the same time.

Thanks John for this information.
We can see a very beautiful constellation ( beacon ? )
