NASA TV using SA D9223 ?

[solarhawk]

Hi All,

I was wondering if anybody has ever tried getting NASA TV on 119 using
a D9223? I can get regular FTA on other sats in non-powervu mode using
this receiver, but can't get anything on the 119 sat. I'm wondering if my
LNB setup is messed up or is something about the format that doesn't
let my receiver pick it up. I have no problems with ProgDVB and a card.
I'm using an Invacom quad LNB. Is there something in the stream that tags
this as non-FTA? I had hoped to park this Scientific Atlanta on NASA TV but
I'm perplexed as to why it doesn't receive.

Thanks!

Are you connected to the circular side of the Invacom Quad?

Another possibility (probability actually) is that the 9223 will not work with a circular DBS LNBF.

You have to be able to enter a L.O. setting of 11250 for the DBS side of the Invacom. Being a commercial receiver, it may only be able to accept settings for a standard LNB (L.O. 10750), since that is what is generally used in broadcast operations.

NASA TV on D9223

Hi Tron,

Thanks for the reply. Looking at the specs for the receiver, it should be
able to tune to that. I have 950-2050 MHZ as the tuner range and also
0 to 15 Ghz as the LO frequency. I had set up the same way you described
using 11250. I was able to get a lock, but the BER was pretty bad. It
shouldn't be, of course. Is there any way to tell if a receiver will use circular
polarization? I figured if the LO is set, should be OK, but maybe not. Also,
I realized I have a 4-way switch mounted on the dish. ProgDVB can handle
this, but the D9223 can't. Could this be messing it up? Anyway, thanks for
the reply and I'll keep you posted.

You have to put it into FTA mode instead of PowerVu mode which is default.

See my instructions below. They should work on a D9223.

Instructions
On www.lyngsat.com find the Free to Air DVB channel you want to watch.

Push Menu button

Push #2 Button

Push #9 Button

You are now in the installer menu

Select the band you want C or KU I chose KU Single Downlink Freq

Enter the Downlink Freq

Enter FEC Rate

Enter Symbol Rate

Enter Polarity

Set Input Select to RF

Push User Button to go to Page 2

Make sure that the C and Ku Band LO (local oscillator) freq matches that of your LNB (you will have to find the paperwork for your LNB)

Push User Button Twice

Now look to see if to the right of the Bit Error Rate says lock or no lock

If it says No Lock adjust the symbol rate in small steps using the chan up and down buttons until it says lock

Push Yes button to store

Now push View button and wait

If the program does not appear check all of your settings and make sure it is locked and signal strength is above 50

Push view

I there is still nothing push view-menu-user-next-yes

Then push user until it says Tune mode: Non PowerVu

Push Yes to Store

Push View and wait

Your Program should appear

Hope they work it should.

Yes, the switch could definitely be the culprit. This is a DiSEqC switch? If so, I doubt the 9223 (or any other commercial receiver) can control it. If you have a DiSEqC-compatible consumer receiver, try slaving the 9223 off of the consumer reciever. Make sure to turn LNB power 'OFF' on the PowerVU when you are slaving it from another receiver. The consumer receiver will select polarity and control the DiSEqC switch.

 

[Wholeshoe]

It could be the switch but I am pretty sure that for some programs out there you have to have it in FTA mode instead of powervu. I know RPTi used to be that way.

NASA TV and SA D9223

Tron/Wholeshoe,

Sorry, I've been out of town and am getting caught up on my posts. I
did have the receiver in FTA mode, but thanks for the instructions. At
least it confirmed I did it right. I forgot to mention that I can get a lock
on the transponder for NASA TV but the BER is pretty bad. That's why
I was wondering if it was a switch problem. In a nutshell...

1) For Linear polarization transponders, the receiver gets FTA channels
such as those on IA5, IA6, G10 etc. The BER is OK and it locks.

2) For circular polarization sats, it locks but the BER is considerably worse
and there is no picture.

When I get a chance, I'll mess with that and see if I can do what you guys suggested. I might take the switch out of line and feed one of the circular
outputs of the Invacom directly to the receiver.

Thanks!

 

[Tron]

That might do it! Let us know if it works...

 

[Wholeshoe]

It sounds like your on the right path. Congrats on having it already in the FTA mode. You can't find much info about that in the manual and I picked it up off an email list.

The newer PowerVu's such as the D9850 tell how to do it in the manual.

The D9850 looks SWEET, but they're very costly...

 

[Wholeshoe]

I use them all the time in commercial applications. Actually for home applications it isn't that great of receiver. It is meant to be tuned to a single channel and left there for years at a time. It has no remote, no disceq.

It is really for a whole different market much like the D9223. But they do work at home when you need them to.

I have a borrowed D9225 that I play with from time to time. I also have a DSR-??? digicipher receiver that has no video output. I need to take the time to pop it open and try to diagnose the problem.

I set up a few D9850s today as a matter a fact. I work for a company that builds headends for cable, DSL, and FTTH companies. I am always happy to "play" with commercial receivers if you ever have any questions on what you can get with one.

Those 9850's was SA's worst decision they have ever made...Pile'o'crap unit....Check out the Tandberg TT1260's...

Would care to elaborate on why you feel this way? Is there some particular problem with the 9850s?

SA decided to leave the "user friendly" invironment to compete with there peers on single rack unit design limiting controls and OSD's for their users. The IRD does not fit in an Adhoc behavore. The network port was their idea of giving back control to the "driver" but really only benifits long term static program distribution. Very sad, but that was their DVB choice...I would guess they will continue their direction to leave the Sat market soon after the Cisco takeover and stick to Consumer STB's...

Thanks Wholeshoe, I know who to ask when I get back to testing my commercial gear. I still have to put my Motorola 4800 through its paces on DCII
