I have several DSR-922's.  I have essentially NO experience with 4DTV, but I would like to hang on to one of these receivers.  Is there any test I could perform to make sure I hang on to one unit which is known to be a good one (non-defective)?  I will be sending the remainder of these receivers to Rick Caylor, so they're already spoken for.

Thank you.  I apologize if this question has already been answered in another thread.

I have no experience with them either, but if it were me, I would try to measure the voltage of the lithium battery holding up the memory, without any AC power...ie the battery is under "load". Although lithium batteries tend to hold their voltage steady until it's time to fail, then they fall like a rock suddenly...
keep the one with the highest voltage. Part with any that don't have any backup battery voltage.
Then I would try to figure out how to manually move my existing dish with it, to make sure it moved OK.

Before I open these units up to find the battery, if a long-time unplugged from 110 AC unit still has the correct time on the clock, could this confirm good battery?

It is the special ID number which is different for each unit which is important. Not the clock. Look for the label on the back side of the unit and then connect up a video display and check for a match. No need to open the unit to  see this. then set up a dish and connect it and look for a DCII lock (small green  light) to show up on the unit display pannel.

(this unit has screen flicker must be bad video)

Any suggestion what LNB type, satellite & transponder to point these to for DCII lock test, boblop?

Getting near dark here soon. I have to water 24 chickens and then hug each one and put them all into bed. Just had high winds and rain pass through with tornados only 30 miles away touching down to  ground. Ok here so far. I have no idea how one would find 24 chickens if high wind got under their wings.

You could do a quick video test on the one unit via C Spans last and only working ntsc channel. I think you may need good ID numbers to get the DC II channels to work though. After becoming a chicken king I have had little time for free tv. I do expect free hot wings and eggs later this year.

The good news is a 922 or 920 can be setup for any type of lnb or lnbfs that you may have.

So would you be talking about C-SPAN on AMC 11 at 3740 V (unknown SR)?  If so I could point a dish there and then hook up the DSR-922.  Then would I just have to figure out what satellite (i.e. "W4" or whatever) and scroll thru its channels to watch for any sign that the unit recognizes that channel?

EDIT:

Or, as you said, "look for a DCII lock (small green  light) to show up on the unit display pannel?"

Use C3 for the Sat. name and it will give you the right polar settings. Set the 922 to Ch 7 and start your search (option 6-4-4 on remote). Happy search!

P.S. It is not a DCII so it will not green light.

C-SPAN on AMC 11 is at 3840V.  It is analog, so it will not show a DCII lock light.
However it may be helpful to tune it in first.  It is on transponder 7.  You should use C3-7.
Once you have it, you will know you are on AMC 11. Then channel up and see if you can lock any DCII channels.  Those should be after C3-23 or 24 depending on what maps are in your receivers.

Progress report:  I tried with both receivers to get C3-7.  Even though both receivers appear to be working in every other way (the video glitches in the General Instrument unit have gone away), I can't get C-SPAN.  With my TBS5925, I used QVC (3925V14323) to make sure I was peaked on 131W/AMC11, then tried the experiment with the DSR-922's.  I eliminated the DiSEqC switch, so the coax is plugged directly into the C-Band LNBF which switches polarity by voltage, and from there to the C/H F-connector in the back of the receiver.

So the on-screen menus work fine as seemingly does everything else on both the General Instrument and the Motorola units, I'm pretty sure I have the dish well-peaked on 131W, and using C3-7 for the channel, with direct connection to the C-Band terminal on this combo C/Ku LNBF I don't get a thing with the DSR-922, but I can switch over and get QFC loud and strong on TBS5925.

Do I just have two bad receivers, or (more likely) am I doing something wrong?

Did you set the LNB Type?
Options, 6, 4, 2

I did play with various options and one of the "nearby" screens showed a signal of 52 which would rise to about 60 as I moved the dish toward the west and lower into the 40's as I motored to the east.  But still just "snow" on the screen for that C-SPAN channel.  Does that signal reading mean that I had things hooked up okay?

I've never used a combo C/Ku LNBF with my 922.  
But be sure you select "C-Band and Ku-Band LNBFs" as LNB Type.
If you chose LNB, the 922 will output a constant 20 volts on both H and V channels and you will only get one polarity with your LNBF.

Your signal seems rather low.  My Options 5 screen shows Signal 80 on C3-7.

I was able this afternoon to get C-SPAN with both receivers, and I do get the DC light on some channels 100 and above.  Is there any channel other than C-SPAN (C3-7) that I should be able to tune / get video on?  I assume from the information just provided that both units have good maps.  The system info screen shows "ZK" mode.  Does this change automatically when a different type of channel is selected?  Thanks for all the newbie help.

If you go to the digital channels on C3 above 100, you should get a screen that says not authorized with the name of the scrambled channel.  If you get that, you should be able to get the free digital channels:  Free Speech tv G7 91w,  and Daystar S3 103w.  It will depend on if the receiver has these channels mapped.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
