Hi everyone,

I'm newly arrived in NZ from across the ditch!! I've had quite a few years experience with digital TV back home in Oz (using MCE and Mediaportal) - but as you probably know it's all pretty much digital via antenna over there (DVB-T)  so I'm still trying to get to grips with all the satellite/DVB-S stuff i'm going to need to do over here (I've move to Nelson where UHF digital isn't available).

So...

I'm planning on having a similar setup to that outlined by mcraenz here (it's a great guide btw).

My questions, mcraenz uses a TechnoTrend S1500 card as one of his DVB-S because it supports a CAM interface for inserting a Pay-TV decryption card - is that right? If so, would this TwinhanDTV Sat-CI (1034 Mantis) DVB-S card from Aussie manufacturers DNTV do the same job? The wite-up says it requires a C-Band or Ku-Band  Satellite dish - are these the ones used in NZ?

Sorry for the newb questions, but it's all a little confusing for a first timer.

Cheers
Rich

Yeah I looked at that card; should do the job. What are you hoping on receiving though? Not sky I hope? Not possible on a DVB-S card there is no CAM available :-(

fyi. I got my Technotrend 1500S from here:

thanks mcraenz... if I give it a try I'll let you know.

Just some q's about your MP guide,

1. What analogue channels are you receiving thru your TechnoTrend. Aren't all the regular analogue channels available via FreeView (as digital)?

2. I assume you have the Freeview card in the TechnoTrend CAM slot for decrypting the Optus C1 IRDETO encrypted channels (SBS, Central 7, etc). Is this right? If so, can you purchase one of these cards from FreeView without buying an entire STB?

3. Will I be able to get the regular terrestrial channels via my DVB-S card without the need of a second HVCPlus box like you have?

4. If I add an extra LNB, will a regular 65cm Sky dish be good enought to receive Optus D1 and C1 (I'm not interested in B3)?

Thanks for your help.

cheers
Rich

There is no encryption of any of the NZ FreeView services on D1, they are all FTA, no CAM or card needed. To access the Optus Aurora services on C1 you will require an Irdeto card from Optus, to obtain this you will be required to prove that you live in a remote area of Australia that has no terrestial coverage. This link explains the service.

The card you have linked to would appear to do what you want, ie NZ FreeView and Optus Aurora, purhaps you have relations in the bush that can provide a card for you.

And yes you can use a standard Sky dish with a dual LNB arrangement to access the C1 Aurora service. Sky actually provide a suitable LNB as matter of course in all new installations that provides access to both D1 and C1, however not for the illegal purpose of viewing Aurora servces.

Regarding using 2 LNBs on one card you will requires a diseqc switch. Also you need to make sure that the card and the card driver and the PVR software (with this specific card) all support DISEQC switching. This can be an issue!

If you're going to use Mediaportal make sure you do your home work specific to this card. If you do choose MP I might be able to help you more in this area. :-)

You would not nessecarily need a Disqec switch, a simple 22kHz switch is all that is required (as the sky dual throat LNb requires). No Disqec at all just 22kHz tone.

Hang on a sec, are you saying I should be able to receive C1 with the standard Sky dual LNB, without having another dish or extra LNB added?  (receive as opposed to view Wink)

Yep sure can however the only C1 beam that can be seen on NZ is 12407MHz Vertical, Symbolrate 30000, FEC 3/4 where you will find the only unencrypted stream is Vpid 80, Apid 81 which is the Optus Aurora tuning info channel, which you will be bored with after 20-30seconds.

The dual throat Sky LNB's contain a 22kHz switch, to change it to see C1, simply apply a 22kHz tone to the LNB feed and it will change over.

I cannot remember which channel it is on a sky box, but on a Sky box you can see the above service to allow Sky techs to check the alignment of the dish is ok for C1. The ability to see C1 is only as a backup to D1 at 160E, when B1 had its woopsy a18months ago Sky got paranoid so rolled out dual thoat LNB's as part of plan B if B1 or D1 died.

Naturally you can add the above parameters to a FTA STB or DVB-S card and see this C1 stream.

ok, thanks for that reply.

Am i correct you can only use one LNB at a time, therefore meaning I'll have to eliminate all Sky boxes off the dish to test it? No results, but i'm probably doing something wrong :)

To get 22kHz to the LNB you will require to be on the DC pass port of any splitter as the non dc pass ports normally have a cutoff around 20MHz, so the 22kHz often wont get through, but every situation may or maynot be different, but being on the DC path should work. You dont need to remove sky boxs, but any box not tuned to a visible C1 transponder will loose signal.

ah, that'll be it. I rigged it so only my Sky box on that loop can change polarity, the PC is passive. Would be nice to know what that C1 test channel is...

Also, if I change LNB, will i need to make sure that my Sky box isn't locking it into hpol?  Or since I'm on another LNB, it won't matter.

Will have another go tonight.

You wouldn't happen to know where to "apply a 22kHz tone" in WinTV? Is it the LNB Switch? (as per ltlman's post in the HVR3000 thread)

Dont know exactly what card you have but looking at the manual for the WinTV-Nexus-S card, the only one I can find, it would seem that the tone will be applied when the second LO setting is engaged which how universal LOs work (ie the tone changes the LO rather than the pickup throat as in a dual thrat LNB as we have here).

Universal LNBs with two LOs are the norm in Europe as they use a larger potion of the Ku band thus need to use to LOs, this switchover of LOs is achieved with the 22kHz.

So if you set LOF1 and LOF2 to 11300MHz, and the switching frequency to 12000MHz (ie so all scanned transponders would appear to be above the switching freq thus it will think its engaging the 2nd LO, where infact its switching the thrat over).

ok, thanks for that




I guess i'd just change that 0 to 12000000 based on what you said? (at the stage this screen was taken, I hadn't added C1)

I choose 12000MHz simply as all the transponders on C1 are well above that and the one you want is 12407, so when you select 12407 it will see it as above 12000 so select LO2, well this is how I guess its logic will work, I suggest a bit of playing around to trick it into action is needed.

Best of luck, report back.

Cyril
