Another Update:

I managed to lock the Mehran TV frequency on 4104 V, SR1600 with an signal level of 6.4 dB. I think this will be the last one I can get with the Precision 2.0m dish as there are no others reasonably close to a lock that I can try for.

After a good bit of time allocated to messing around on 38.0 East I managed a total of 11 frequencies locked with pictures. I have attached below a couple of channel screen grabs from the Mehran TV, the latest one locked.

.
An excellent set of results M.B. - From what is a very difficult satellite to catch anything from here in the uk . and i,m well aware of how much time you will have spent getting those results too :cool:

As i think we discussed,, each transponder seems to require its own unique dish position and - or l.n.b. / scalar adjustments to get the best from... And on top of this the transponder signal strengths seems not to be constant either - but varies day to day / week to week . The last one that i struggled so hard to lock a few nights ago (in clear weather) now seems to stay locked all day and runs without freezing (in cloud and rain), .... whereas others i locked without issue a week ago wont lock, or will only lock briefly in the evenings.

So i would not rule out other transponders being possible to lock in the future .. Its just very time consuming l.o.l.

@John & @nelson_b

Thanks, I think I may have spent more time tweaking the dish setup and scanning 38.0 East than for any other satellite. The Precision 2.0m dish is due to be relocated back onto the mobile platform on the patio in the next day or so for a quick sniff at a few Westerly satellites in C-Band so I will lose visibility of 38.0 East.

I have attached below what will probably be the final scan result table for 38.0 East from this current period of testing.

Thanks for your scan - chart ...
I,m going to stay with this sat a little longer, and when the weather and time allows it - i want to try a Zinwell l.n.b on some of these tricky transponders, and see how it compares to the BSC 421 that i,v been using.

Agree with you here Nelson - a right quirky little bird is this one

...I,m going to stay with this sat a little longer...

Before the dish gets relocated back to the mobile platform I had another chew at the bone but only ended up swallowing a bit of gristle. I was trying to get 3770V which needs 7.9dB for a lock, unfortunately I could only manage 7.4dB stable with occasional flickers up to 7.5dB - 7.6dB.

The main issue with 3770V is that when the dish is aligned accurately on 38.0 East the frequency is getting swamped out with bleed over from 40.0 East. At that alignment I am getting about 3.1dB signal level for 3770V. By moving the dish about 3/4 of a degree West it finally escapes the bleed over from 40.0 East and the 3770V signal rises to 7.4dB.

The re-alignment West by 3/4 of a degree for the Precision 2.0m dish is the optimum. Anything less and the 3770V signal is reduced by bleed over from 40.0 East, anything more and the dish is getting to far off the satellite.

So close ... The challenges with this sat are quite addictive .. l.o.l.

I,m not affected by the bleed over from 40 E to the same degree as yourself .... but i also have to move a little West for some transponders to get the best from them ...

I have mostly a free day today - and the weather is quite calm and dry .. so i think i will have a go here with the Zinwell l.n.b. this afternoon / evening , just to satisfy my curiosity.

Yes, the wider beamwidth of my 2.0m dish is the deal breaker for almost all of the frequencies on 38.0 East below 4000 MHz. The only frequency I can lock below 4000 MHz is Kohenoor News on 3952 V which has no close proximity frequency on 40.0 East.

Curiosity satisfied .. :cool:
The Zinwell didn't reveal any more channels l.o.l. ... but if i fiddled around enough it would equal in general the BSC 421 that i,v been using .
I also tried an ESX 241 which again could be made to give good results but was very tricky/sensitive to adjust
TitaniumCIW-Pll was generally 0.5 db down overall no matter how much i fiddled with it
The best results were with the old Gardinier 20k gardinier.jpg no new transponders but a slight increase in strength on most that i tried it on gardinier result Khyber ch.jpg

Nice one !

Have you been able to get any of the frequencies below 4000 MHz apart from Kohenoor News with the 1.8m dish? Depending on the beamwidth angle of your dish you might be able to grab 3770V if you move off the satellite slightly to the West?

I keep trying MB. Might have another scan..

... conditions seemed to be more favorable last night and this morning for 38°E and up here in North Nott's the 2.2 managed to grab 7 Tp's with 10 programs between them - still a bit of a juggling exercise though to slightly nudge out strong destructive signal influences from next door at 40°E. The elusive '92 News' @ 4023 V was grabbed but did not lock.

Nice one John ...
I,v been a bit busy the past few days to check any signal strengths here ... its a funny old satellite and individual t.p.,s vary regardless of the time of day or weather conditions etc.

Nice one.

What are the frequencies for the DTV channels and CH-3, I am not sure if I locked them?

'CH-3' is 4082 V.
The 'DTV 1,2 &3' are all on I THINK - 4135 V. I scrubbed the original scan Dave , i'll try and re-capture.

I had locked and renamed CH-3 to ATV Pakistan but I did not manage a lock on 4135V, best I had was 8.2db and it needed 9.4db. I have put the Ku-Band feed back on the dish now so missed the opportunity last night to try to lock 4135V :(

Same here .. I,v always been 1.0 to 1.5 d.b. below lock on 4135V .. still set up for C band here - will keep an eye on Paksat for a little while longer .

Had a little time to spare this afternoon so went out and optimized the l.n.b./ scalar for 4135V and although i had flashes up to 8.7 db it hovered around 8.2/8.3 mostly

But checking through the unlocked t.p list ... a surprise ... locked 3825 V 4800 - this has always been 1.0 db or more below previously.

The EXP Channels at 3825 V 4800 were very short lived ...
But i noticed 4135 V was gaining strength here in the evening .. so left a monitor on .. fell asleep watching some t.v on Netflix ... when i woke just after midnight it was locked - so gabbed the camera for a pic or two .... it is still locking intermittently this morning . The challenges with this Sat are very addictive - l.o.l.

Typical, I switch the feed over to Ku-Band and there is a glut fest of increased signal levels that you boys are mopping up. I am gonna return to this satellite at some point with a dish worthy of the challenge, my wimpy 2.0m bin lid just aint up to the task for sucking decent juice from this bird.
