68.5 East C band result

[nelson_b]

hi --
Encouraged by the result using a 1.2 dish in march this year -- http://www.satellites.co.uk/forums/topic/157980-685-east-test-setup/ ) post 22,--

and rising to the challenge - i decided to get the Alcoa 1.8 down onto the yard and set it up for C band and point it at 68.5 east (elevation 2.4 here) as with ku band here, the signal slowly rises and then fades back to zero .
i tried all 3 C band l.n.b.,s that i have - and an old chaparral co rotor with the plate removed --- it gave the best result - a full 1.0db better - than the others .
the signal from 68.5 E reached its best peaks around mid afternoon and i got 2 short periods of lock of about half a min - just long enough to grab a picture of the 9.0 db lock - and scan the channels from 4155 V 22500 into the receiver .(encrypted channels , -- just my luck).
still getting signal tonight but just around 6.0 db now at best.

A lot of time spent today for a small result - but it was enjoyable -- l.o.l.

regards ----

hi -
Update -- left the F15 blind scanning - (which i had done many times today) without any
success.
came back and was amazed to find that this time it had logged a further 5 transponders.

4129 V 10369 Jaya plus ---(encrypted
4093 V 2962 YTN World
4071 V 4339 Hope Channel India
4054 V 4399 Ariane Tv
4060 V 3529 CTS (south korea)

have some photo/screenshots for some of the above -- will sort out tommorrow

very pleased with these results -- did not expect this much fom my location/low elevation -----

..and now the bit where I say ..how jealous I am that you can see this portion of the arc with your alcoa ..
Sadly the only dish I have with a clearish view of 68.5 E is the TD88 ..
Congrats Nelson ..
Seriously good results.
Some pix soon perhaps ?...or is everything encrypted?

 

[nelson_b]

hi -
this setup with the alcoa is only temporary - it cant stay here long - just a few days
4 of the above t.p.s were clear but did not last long due to the fading effect --
need to go out now -- some pics later.

cheers --

 

[nelson_b]

hi -
some pics from last night -- had to grab them very quickly - before the signal faded .
still getting short periods of lock on a couple t.p.,s this morning --
hope to get some time to play again tonight --

cheers --

 

[Captain Jack]

Pretty cool!

 

[nelson_b]

hi -

tried scanning for horizontals this time -- picked up 4 t.p.s.

4117 H 3333 -- Samaa tv

4006 H 2990 Dunya News

3740 H 26590 N.H.K.

3974 H 19500 Zee Turner Mux (encrypted)

i,m sure more could be obtained , but the rise and fall of the signal makes it very hit and miss --- its becoming frustrating and time consuming - l.o.l.

non of the locked channels stay view-able for more than 1 min at best - then disappear for 5 min or more --
anyway i,v wondered for long enough in the past if it was possible to get 68.5 E - C band from here with 1.8 . so now i know that it is -- "sort of "

well done nelson very envious,i use to pick up this sat but a block of flats stopped that,nice pics shame its only temporary i am sure it would be interesting to see what else you could pick up.

 

[nelson_b]

cheers "pride"
its a shame you have lost your view of this sat --
being so much further south the fading effect would i,m sure , be much less.
i,m receiving here through a gap between buildings - and there is a small tree possibly affecting the signal --

 

[Vipersan]

fwiw I can see this bird in Ku with the TD88
but sadly not Christina.
Even in Ku the fading low elevation effect is very evident.
I can't even blame the TT ..
Christinas view is blocked by a 1930s semi ..so short of taking a JCB to the house ..this one is out of bounds to me in C.
Kudos to Nelson for giving us a taster.

Ku band is easy as long as you can see it. Yes, there are variations but I don't experience complete signal dropouts as it's quite a strong sat.

 

[nelson_b]

cheers Vipersan
its a pity about that semi being in the way - the extension panels on your "Christina" Alcoa
would help override the fading effect i think ..

i,v altered the dish to get 66 east tonight and can see signal from some transponders -
no locks yet -- but the peaks are improving as the day cools down
i,v played around with the l.n.b,s again -- but the co rotor (20k) minus its plate is still the winner with this dish on these 2 eastern sats. i expected the BSC-421 to be best ?

@ "Kveys" ---- do you receive any t.p,s from 66 east if so which is strongest for you ?

Admittedly 3845V strongest. Verticals are strong and horizontals very, very exact-skew need. Maybe most difficulty (C-band) satellite about skew. For e.g now not any of H give signal but still fine tuning work here after the dish move earlier. Strongest H = 3984H (FEC 2/3!). From pic 2 you´ll see frequencies catched here.

thanks for the info -- "Kveys"
i, going to connect up an old receiver to the co rotor - to get precise control of the probe position -- save me having to keep turning the whole thing to adjust it .

cheers --

 

[Kveys]

What about Intelsat 906 (64.2E)? At first when I started my C-band observation at last winter (eeehhee I bought mesh for christmas present for me ) I catched also 3765R/3720R. Since then only strong Tanzania/Mozambik (3642R/3654R). Can you check this also? Are there anything else than these 2 anymore really?

 

[Kveys]

Btw. 1st time ever signal from 4013H (68.5E). These 8PSK channels really s*cks. Most of freqs however catced from this sat.

 

[nelson_b]

nice one --
i could not catch that transponder --

i agree that - "These 8PSK channels really s*cks." ----

i will check - Intelsat 906 (64.2E) another night maybe tommorrow,
my i.8 Alcoa dish is a fixed mount so i,m just exploring one sat each evening at the moment

cheers ---

 

[nelson_b]

ok -
i managed to lock and scan 2 transponders on 66East - they drifted in and out of lock for around 15 mins only - i can see some signal from most transponders on this sat, H and V - but they never quite make it to lock -- just the 2 verticals

3885 V 30000 --- Sun tv network (all encrypted)

3845 V 27692 --- Tata communications (part encrypted)

the fading is slightly less with this sat - but overall its weaker for me here than 68.5 E

(screen pics dreadfull quality sorry - taken in a rush from outside monitor )

cheers.

 

[Vipersan]

Your efforts are appreciated Nelson ..
I know I have no chance of 68.5 ..but 66 and 64 ..just maybe come winter..
Always useful to know what to go for.

Scan Intelsat 20 both C- & Ku-band

<a class="" href="http://www.satellites.co.uk/forums/user/296628-nelson-b/" title=""><span>nelson_b</a> </span>"old chaparral co rotor with the plate removed --- it gave the best result - a full 1.0db better"
Interesting idea to have plate removed, will try it, has an old corotor.
Must get just get lose my present corotor, the screw is properly secured, any idea how I will get the screw lose?
